Bearings for Material Handling System: Adjustable Combined Bearings AWD074-78

Bearings for Material Handling System
Bearings for Material Handling System Track roller bearings can withdraw heavy load rating and shock load rating by their thick outer race. They are ready-to-fit units and are intended for all types of cam drives, tracks, conveyors, material handling systems and so on.
According to customer's application, the OD surface can be designed to be flat , crowned and other special ones. Cam rollers with crowned runner surfaces should always be used where angular misalignments with respect to the track expected and edge stresses kept to a minimum.
Track roller bearings are based on ball bearings, needle roller bearings as well as cylindrical roller bearings. Because of the wide variety of designs they are suitable for the most diverse operating conditions.
Tolerances:
WD track roller bearings are produced according to Normal tolerance P0 standard, except for the tolerance of the crowned runner surface diameter.The values for tolerances tally with ISO 492.
Clearance?
C2, C0, C3, C4, C5 radial internal clearance are available and also special radial internal clearance is available as customer's application providing the clearance limits are as specified in ISO 5753.
Load rating?
Dynamic load rating conform to ISO281/1 and static load rating conform to ISO76.
Lubrication ?
The track roller bearings, filled with lithium grease, have a good anti-rust capability and can work among the temperature range from-30?to+120?. Generally speaking, they are greased for life and are maintenance-free under normal working condition. However, if they are subjected to moisture or solid contaminants, or if they keep runing for a long periods under temperatures above 70?, they should be relubricated with same grease by the oil hole in the inner race or other lubrication method. High and low temperature grease are also available according to customer's request.
The WD track roller bearings consist of:
? Combined bearings
? Cam followers
? Mast rollers and chain pulleys
? Cam roller bearings
? Supporting rollers
? Other non-standard rollers

WD Combined Bearings are particularly suitable for truck lift columns and all other shifting and convying systems requiring profiles.They can afford load from both axial and radial direction at the same time.With the optimzed structure, the mount space can be saved, and the usage is also simple that just to weld the pivot in the mount plate, it is not necessary to dismantle the whole set. The radial bearings are particularly suitable for automation and shift systems, which do not require heavy axial loads, and they come from the combined bearings and maintain the same features of construction.
