CAT 564-6963 is a Caterpillar push arm spherical plain bearing specifically designed for graders, loaders, and other equipment. It is suitable for the hinge joint between the push arm and the chassis/working device, primarily designed to absorb shock and angular displacement. Key information is as follows:
Core Parameters
Item Details
Type: Self-lubricating spherical plain bearing (with PTFE composite liner), capable of withstanding radial + bidirectional angular displacement, suitable for heavy-duty hinged applications
Inner Diameter: Approx. 3.5 inches (88.9 mm), matching CAT push arm pins of corresponding specifications
Outer Diameter: Approx. 5.0 inches (127 mm), matching push arm mounting holes
Width: Approx. 2.5 inches (63.5 mm), ensuring load-bearing area and structural strength
Material: Outer ring is high-strength alloy steel, inner ring composite layer contains PTFE + bronze mesh, self-lubricating and maintenance-free, shock-resistant and wear-resistant
Lubrication Self-lubricating design, suitable for oil-free field operations, also compatible with grease lubrication.
Structure: Spherical contact, allowing ±5°~±8° angular displacement, compensating for installation errors and working condition deformation.
Applications: Suitable for articulated parts such as pushrods, linkages, and steering mechanisms of Cat 140M/160M series graders and 966/972 series loaders, absorbing impact loads and angular displacements during operation to ensure smooth operation.
Used at the connection point between the working device and the frame, withstanding frequent swaying and heavy loads, suitable for infrastructure and road construction, extending the service life of pushrods and pins.
Performance Characteristics: Self-lubricating composite liner with low friction coefficient, reducing pin wear, long maintenance-free cycle, and reducing equipment downtime.
Spherical structure absorbs multi-angle displacement, compensating for installation errors and working condition deformation, avoiding stress concentration, and improving structural reliability.
High-strength alloy steel outer ring + wear-resistant liner, impact-resistant and corrosion-resistant, suitable for harsh outdoor working conditions, service life is about 40% longer than ordinary sliding bearings.
