Clamp coupling

Clamp couplings avoid damage tothe shaft and absorb misalignment.

Avoid impacting force whenfitting drive components togearbox shafts. Internaldamage to the gear trainmay occur.

An outrigger bearing supportsthe shaft thus minimising thebending load and protectingthe shaft from failure.

Customer modified gearboxes have an invalidated warranty.

We always recommend anymodifications that the customermay require in terms of gearboxshaft length, diameters or keywayconfigurations be made by us priorto assembly. Alterations undertakenby the customer on a finished boxmay lead to internal gear damageand subsequent premature failureof the gearbox.

Gear, pulley or sprocketmounted at the outerextremity of the input shaft

may induce bending andeventual failure of the shaft.

Mounting the gear, pulley orsprocket as near as possible to thegearbox body helps reduce

leverage on the shaft, althoughshaft fatigue may still result.

Shell Nerita Grease HV - Synthetic High Speed Bearing GreaseA very high performance grease specially designed for the lubrication of heavily

loaded, high-speed bearings. It consists of a blend of lithium soap, Shell XHVIsynthetic base oil and carefully selected additives recommended for use whereconventional greases are inadequate in anti-wear and extreme-pressureproperies or in their oxidation resistance. Suitable over a wide temperaturerange from -30C to a peak of +130C, it gives extended bearing and grease life.

Performance Features Outstanding mechanical stability Excellent wear protection Long operational life Heavy load capability Lead and nitrite free Good oil separation Wide operating temperature Range

Grease Technical DataShell Alvania Grease HDX2

GEARBOXES


Shell Alvania Grease HDX2 - High Performance Grease Containing Solid LubricantA very high performance grease the lubrication of industrial bearings

subjected to the most arduous conditions. It is based on a high viscosity indexmineral oil and a lithium/calcium thickener and contains extreme-pressure,anti-oxidation, anti-wear, anti-corrosion and adhesion additives. It alsocontains molybdenum disulphide to enhance its EP properties. The essentialqualities of Shell Alvania Grease HDX2 are its mechanical stability, waterresistance, adhesion and exceptional performance in shock loaded conditions.It is recommended for the lubrication of shock loaded heavy duty bearingsworking in damp hostile conditions.

Gearbox Grease Filling

GEARBOXES

112 516-867-5665 516-867-5656

Operating ambient temperature range = 0C to 70C The grease in most applications will run at 80C but if speed and load are increased,

the temperature of the gearbox will rise and may cause damage to the unit. Handmotion will not cause a problem because no thermal build up will arise until youmotor power the unit.

Gearboxes can be packed with wide-range temperature grease operating between -55C to +155C.

Rubber seals (nitrile) oil seals: maximum operating temperature = +100C Carbon steel bearings: maximum operating temperature = +150C

(if fitted with high temperature grease) Stainless steel bearings: maximum operating temperature = +288C

(if fitted with high temperature grease) Standard bearings: maximum operating temperature = +80C (including hand motion) Gearboxes are greased for life. Refilling is only required when boxes are disassembled

for refurbishment. Overfilling will cause excessive heat build up and potential failure. We are able to modify standard gearboxes to customers specific requirements. Damage caused by customer modifications will invalidate the gearbox guarantee. We recommend that shafts are connected by flexible couplings. Our gearboxes are designed as speed reducing units, not as multipliers. If used in a

speed increasing capacity, service life is not guaranteed. Customers will always need to test the units themselves in their particular application

to ensure it is adequate for the job and has the desired results for them.

DO NOT FILL !

GREASED FOR LIFE

Greasing is onlyrequired if the

gearbox is to beused in special

applications or if itis being refurbished
