Idlers
= Idler rollers are provided with double labyrinth sealing
= Idler rollers are dust proof, water proof and weather proof
= Idler rollers are drop-in type and rolls can be removed without dismantling the brackets from the conveyor
structure
= All rolls of similar belt width are interchangeable
= High quality rollers are capable of carrying heavy load
= Idler bases are designed to provide a minimum gap between rollers, giving added protection to the conveyor belt
= The inverted angle base frame has a self cleaning action by virtue of its sloping upper surface which eliminates
the possibility of rolls jamming

Idlers
For nearly five decades TRF Ltd. has been manufacturing
conveyor idlers for all sectors of the industry. Based on its vast
experience, the Company offers a complete range of conveyor
idler sets for a wide variety of belt conveyors designed to
provide economic and efficient operations. Coal, coke, lignite,
iron ore, cement, fertiliser, slag, etc are amongst the many
materials which are effectively handled by appropriately sized
idlers. TRF Idlers are available for belt widths upto 2400mm.
They can however, be designed for higher belt widths. TRF
idlers range from cover carrying, return, self-aligning carrying
and return, impact, transition, picking and feeding, self-
cleaning return, V-type return, garland type carrying and
return functions. Both, sealed-for-life idlers with deep groove
ball bearings and regreasable type idlers with one-shot one-
point lubrication system with taper roller bearings are
available in the TRF range.
These idlers are equipped with deep groove ball bearings
covering 20 mm to 45 mm diameter. The idlers are lubricated
for life. Regreasing arrangement of individual rollers is
provided to customers on request.
These idlers are provided with 20 mm and 30 mm diameter
taper roller bearing. The design ensures complete re-
lubrication of all six bearings from one accessible grease
fitting. The pressure relief fitting at the other end ensures that
the idlers are completely lubricated.
The idlers are designed as per
IS-8598/ISO-1537/IPSS-2-03-004-85 specifications.
These are made from deep drawing quality steel. Housings
are welded to both ends of the tube simultaneously by an
automatic welding machine forming a mono-block design to
ensure rigidity, lower rotating weight and minimum out-of-
roundness.
Special ERW tubes as per IS-9295 with close tolerances are
used. Idlers with seamless steel tubes can also be
manufactured on demand. Tubes are recessed at both ends
simultaneously by a special purpose machine to guarantee

concentricity.
Idlers are provided with specially designed, laboratory-tested,
multi-labyrinth, non-contacting type seals which keep dust,
moisture and dirt away from the bearing. A waterproof
weather cap at the roller end prevents water entering
alongside the shaft. A specially designed back-seal prevents
grease from entering the roller.
The idlers are provided with shaft made from bright bar
conforming to IS-9550. Shaft conforming to EN-8 or C-35 or
C-45 chemical composition. The shafts are ground on a
centreless grinding machine to provide finish of a very high
degree throughout the length.
The assembly of life-sealed type idler rollers, is supported on
fabricated brackets on an inverted angle base board forming
a truss-like construction which provides extra rigidity. The
idlers with one shot lubrication are supported on cast-
malleable steel/fabricated brackets and are mounted on

channel base board.
All idler rollers are lubricated with hi-lithium based grease
during assembly and no subsequent lubrication is required.
All isler components are tested at various stages of
manufacture. Idler rollers are fully tested for free running, dust
and water penetration, dynamic friction factor and high speed
at TRF laboratory which is equipped with modern testing
facilities.
TRF can supply rollers to suit existing installations
maintaining TRF standard internal construction. The roll dia,
roll length, shaft length and shaft ends are tailor made to suit
the customer’s requirement.

Idlers
For nearly five decades TRF Ltd. has been manufacturing
conveyor idlers for all sectors of the industry. Based on its vast
experience, the Company offers a complete range of conveyor
idler sets for a wide variety of belt conveyors designed to
provide economic and efficient operations. Coal, coke, lignite,
iron ore, cement, fertiliser, slag, etc are amongst the many
materials which are effectively handled by appropriately sized
idlers. TRF Idlers are available for belt widths upto 2400mm.
They can however, be designed for higher belt widths. TRF
idlers range from cover carrying, return, self-aligning carrying
and return, impact, transition, picking and feeding, self-
cleaning return, V-type return, garland type carrying and
return functions. Both, sealed-for-life idlers with deep groove
ball bearings and regreasable type idlers with one-shot one-
point lubrication system with taper roller bearings are
available in the TRF range.
These idlers are equipped with deep groove ball bearings
covering 20 mm to 45 mm diameter. The idlers are lubricated
for life. Regreasing arrangement of individual rollers is
provided to customers on request.
These idlers are provided with 20 mm and 30 mm diameter
taper roller bearing. The design ensures complete re-
lubrication of all six bearings from one accessible grease
fitting. The pressure relief fitting at the other end ensures that
the idlers are completely lubricated.
The idlers are designed as per
IS-8598/ISO-1537/IPSS-2-03-004-85 specifications.
These are made from deep drawing quality steel. Housings
are welded to both ends of the tube simultaneously by an
automatic welding machine forming a mono-block design to
ensure rigidity, lower rotating weight and minimum out-of-
roundness.
Special ERW tubes as per IS-9295 with close tolerances are
used. Idlers with seamless steel tubes can also be
manufactured on demand. Tubes are recessed at both ends
simultaneously by a special purpose machine to guarantee

concentricity.
Idlers are provided with specially designed, laboratory-tested,
multi-labyrinth, non-contacting type seals which keep dust,
moisture and dirt away from the bearing. A waterproof
weather cap at the roller end prevents water entering
alongside the shaft. A specially designed back-seal prevents
grease from entering the roller.
The idlers are provided with shaft made from bright bar
conforming to IS-9550. Shaft conforming to EN-8 or C-35 or
C-45 chemical composition. The shafts are ground on a
centreless grinding machine to provide finish of a very high
degree throughout the length.
The assembly of life-sealed type idler rollers, is supported on
fabricated brackets on an inverted angle base board forming
a truss-like construction which provides extra rigidity. The
idlers with one shot lubrication are supported on cast-
malleable steel/fabricated brackets and are mounted on
Sealing

Idlers
For nearly five decades TRF Ltd. has been manufacturing
conveyor idlers for all sectors of the industry. Based on its vast
experience, the Company offers a complete range of conveyor
idler sets for a wide variety of belt conveyors designed to
provide economic and efficient operations. Coal, coke, lignite,
iron ore, cement, fertiliser, slag, etc are amongst the many
materials which are effectively handled by appropriately sized
idlers. TRF Idlers are available for belt widths upto 2400mm.
They can however, be designed for higher belt widths. TRF
idlers range from cover carrying, return, self-aligning carrying
and return, impact, transition, picking and feeding, self-
cleaning return, V-type return, garland type carrying and
return functions. Both, sealed-for-life idlers with deep groove
ball bearings and regreasable type idlers with one-shot one-
point lubrication system with taper roller bearings are
available in the TRF range.
These idlers are equipped with deep groove ball bearings
covering 20 mm to 45 mm diameter. The idlers are lubricated
for life. Regreasing arrangement of individual rollers is
provided to customers on request.
These idlers are provided with 20 mm and 30 mm diameter
taper roller bearing. The design ensures complete re-
lubrication of all six bearings from one accessible grease
fitting. The pressure relief fitting at the other end ensures that
the idlers are completely lubricated.
The idlers are designed as per
IS-8598/ISO-1537/IPSS-2-03-004-85 specifications.
These are made from deep drawing quality steel. Housings
are welded to both ends of the tube simultaneously by an
automatic welding machine forming a mono-block design to
ensure rigidity, lower rotating weight and minimum out-of-
roundness.
Special ERW tubes as per IS-9295 with close tolerances are
used. Idlers with seamless steel tubes can also be
manufactured on demand. Tubes are recessed at both ends
simultaneously by a special purpose machine to guarantee

concentricity.
Idlers are provided with specially designed, laboratory-tested,
multi-labyrinth, non-contacting type seals which keep dust,
moisture and dirt away from the bearing. A waterproof
weather cap at the roller end prevents water entering
alongside the shaft. A specially designed back-seal prevents
grease from entering the roller.
The idlers are provided with shaft made from bright bar
conforming to IS-9550. Shaft conforming to EN-8 or C-35 or
C-45 chemical composition. The shafts are ground on a
centreless grinding machine to provide finish of a very high
degree throughout the length.
The assembly of life-sealed type idler rollers, is supported on
fabricated brackets on an inverted angle base board forming
a truss-like construction which provides extra rigidity. The
idlers with one shot lubrication are supported on cast-
malleable steel/fabricated brackets and are mounted on

channel base board.
All idler rollers are lubricated with hi-lithium based grease
during assembly and no subsequent lubrication is required.
All isler components are tested at various stages of
manufacture. Idler rollers are fully tested for free running, dust
and water penetration, dynamic friction factor and high speed
at TRF laboratory which is equipped with modern testing
facilities.
TRF can supply rollers to suit existing installations
maintaining TRF standard internal construction. The roll dia,
roll length, shaft length and shaft ends are tailor made to suit
the customer’s requirement.

All idler rollers are lubricated with hi-lithium based grease
during assembly and no subsequent lubrication is required.
All isler components are tested at various stages of
manufacture. Idler rollers are fully tested for free running, dust
and water penetration, dynamic friction factor and high speed
at TRF laboratory which is equipped with modern testing
facilities.
TRF can supply rollers to suit existing installations
maintaining TRF standard internal construction. The roll dia,
roll length, shaft length and shaft ends are tailor made to suit
the customer’s requirement.
