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 bearings for material handling system consist of roller bearings for forklift portal, chain guided roller bearings for forklift and standard combined bearings.With thick outer race, these bearings could afford heavy contact load.the contact working area of forklift portal bearings and standard combined bearings has been optimized to ensure a more reasonable load distribution when there is contact stress.WD bearing group could also manufacture the special or non-standard bearings and customizing bearings according to the customers' demands.
