Load rating:

Dynamic load rating conform to ISO281/1 and static load rating conform to ISO76.


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 running for a long periods under temperatures above 70's, they should be relubricated with same grease by the oil hole in the inner race or other lubrication method.
