Structure and Compatibility Characteristics
Compact Thrust Structure: Cage-type needle roller design with small axial height, suitable for axial positioning parts with limited space, capable of withstanding unidirectional heavy axial forces, and also has impact resistance.

High-Precision Needle Roller Assembly: The needle rollers are precision ground and sorted, with high dimensional consistency and uniform contact, reducing local stress concentration, suitable for frequent start-stop and variable load conditions.

Reinforced Load-Bearing Design: Large contact area between the needle rollers and the thrust surface, low unit pressure, suitable for the axial positioning and load transfer requirements of engines, gearboxes, and rotary mechanisms.

Compatible Machine Models and Application Scenarios

Excavators: 320D, 336D, etc., slewing motor thrust end caps, travel reducer end caps, suitable for axial positioning and impact load conditions.

Loaders: 950M, 966M, etc., gearbox output shaft thrust end caps, boom cylinder supports, suitable for axial load transmission during frequent movements.

Bulldozers: D6T, D7E, etc., final drive end caps, steering mechanisms, suitable for axial positioning requirements during heavy-duty traction.
