A two-directional thrust tapered roller bearing with a liner and a manufacturing method
By introducing adjustment and lubrication components into the double-direction thrust tapered roller bearing, the problems of unadjustable free clearance rings and inconvenient lubricant addition have been solved. This has enabled the bearing to achieve stability and rapid lubrication under extreme loads, extending its service life and improving the stability of equipment operation.

AI Technical Summary
Existing double-direction thrust tapered roller bearings cannot automatically adjust the free clearance ring when subjected to excessive loads, which affects the bearing's service life and makes lubricant addition inconvenient, thus affecting the stability of equipment operation.
The design incorporates a double-direction thrust tapered roller bearing with an inner bushing. It employs an adjustment assembly to adaptively adjust the free clearance ring and a lubrication replenishment assembly for rapid lubrication addition. This assembly includes a slider, spring, and rack and pinion structure to achieve adaptive adjustment of the free clearance ring and rapid lubrication replenishment.
This achieves improved bearing structure stability and extended service life under extreme loads, while the rapid addition of lubricating oil reduces friction and heat, improving the stability and convenience of equipment operation.
