Applications and Applications

Compatible Equipment: CAT PR-750B grader, used at the final drive output end and drive axle hub end to bear high radial loads, limit hub radial runout, and ensure transmission accuracy and stability. Application Scenarios: Suitable for low-speed, heavy-load, dusty, and vibrating operating conditions, such as drive axle power transmission and final drive gear shaft support during grader operation, preventing shaft vibration and wear and extending component life.

Compatible with: Compatible with bearing housings, seals, and lock nuts. Accurate positioning and reliable sealing after installation, without interference.

Installation and Maintenance Points:
Installation: Clean the mounting surface and journal, and cold-press installation using a special tool; after installation, check the radial clearance (0.020-0.035mm) to ensure no jamming.

Maintenance: Check bearing temperature and abnormal noise every 250 hours, and regularly replenish lithium-based grease to prevent dust and moisture ingress.

Replacement: Use a puller tool for disassembly, avoiding hammering; install the new part in the original position, ensuring the clearance meets requirements, and replace the seals simultaneously.
