Matching Relationship: 1-2 pieces per track pin, used with 093-5123 slippers, track pads and track pins

Compatibility and Application

Compatible Parts: Connection between track pin and track pad/track link, installed on the outside of the track pin, supporting the rotation of the track pin and reducing friction loss.

Application Scenarios: Suitable for small-scale earthmoving, municipal engineering, and other applications. Compatible with the 650GT track assembly, ensuring smooth track operation and reducing malfunctions.

Core Functions: Bears radial loads, reduces friction between track pins and track shoes, cushions impacts, extends track system lifespan, and improves walking efficiency and stability.

Installation and Maintenance Points:

Installation: Clean bearings, track pins, and mounting holes, checking for deformation, cracks, and rust. Apply lithium-based grease and press into place using a special tool, ensuring no jamming and smooth track pin rotation.

Maintenance: Check bearing lubrication and wear every 50-100 hours, replenishing grease as needed. Replace bearings immediately if needle roller wear, cage damage, or excessive clearance is found.

Replacement: During replacement, simultaneously inspect track pins, track shoes, and other components, prioritizing original parts. Ensure size and material compatibility. After installation, test track operation for any abnormalities.
