The Cat 4T-6767 is the core pusharm bearing at the hinge between the pusharm and the frame of Caterpillar bulldozers. It is compatible with mainstream models such as D6H/D6R/D5R and features a spherical or tapered roller bearing structure that can withstand heavy loads and impacts, ensuring precise and smooth pusharm swing. The following are its structured core parameters and application highlights:
Project Details
Chinese Name: Caterpillar 4T-6767 Blade Push Arm Bearing
English Name: Cat 4T-6767 Blade Push Arm Bearing
Compatible Models: D6H, D6H II, D6R (II/III), D5R, D5R2, and other bulldozers
Material: Chromium bearing steel (e.g., GCr15), hardened/carburized, hardness HRC58-62, wear-resistant and fatigue-resistant
Structure Type: Spherical/tapered roller bearing, capable of withstanding radial + bidirectional axial loads, suitable for push arm swing and tilting actions
Core Dimensions (Official Reference): Inner diameter 63.5mm (2.5 inches), outer diameter 120.65mm (4.75 inches), width 38.1mm (1.5 inches)
Function: Core rotating component at the hinge, transmitting load, absorbing impact, reducing friction and wear, and ensuring bulldozing operation control accuracy
Installation and Maintenance Before installation, clean the coaxial cable and lubricate it regularly with lithium-based grease to prevent debris from entering. Replace the cable immediately if jamming or increased clearance occurs.
