CAT 134-2733 Bearing-Aligning

CAT 134-2733 is a Caterpillar genuine self-aligning spherical plain bearing, suitable for articulations and connecting rods in tracked tractors and tooling, used to withstand heavy loads and angular misalignment, and adapted for impact and vibration conditions. The following are key information.

Core Technical Parameters

Item Details
Part Model CAT 134-2733 (Single Spherical Sliding Bearing)

Material: Bearing steel, inner spherical surface hardened, wear-resistant and impact-resistant, surface anti-rust coating

Key Dimensions: Inner diameter 76.2mm, outer diameter 158.75mm, inner ring length 88.9mm, spherical contact angle adapted for angular deviation compensation

Compatible Models: Tracked tractors D6M, D6N; Tooling fixtures 834G, 836G, used in connecting rods, hinge points, etc.

Performance Characteristics: Self-aligning capability, compensating for installation deviations and working angular displacement; strong load-bearing capacity, suitable for heavy loads and impact conditions; stable coefficient of friction, wear-resistant, suitable for low-speed oscillation/rotation scenarios

Structure and Core Functions: Self-aligning compensation: The inner and outer spherical surfaces fit together, allowing a certain angle (usually ±2°-±5°) of angular deviation, compensating for installation errors and component deformation, avoiding localized wear caused by edge contact.

Heavy-duty bearing: The large spherical contact area allows it to withstand large radial loads and bidirectional axial loads, making it suitable for the frequent start-stop and heavy-load operation conditions of construction machinery, ensuring stable component operation.

Stable friction and wear resistance: The bearing steel material and hardening treatment reduce friction and wear, extending service life. It is also suitable for low-speed oscillation or rotation scenarios, maintaining stable transmission efficiency.

Suitable scenarios and installation/maintenance points:

Suitable scenarios: Primarily used in tracked tractors, tooling linkages, suspension mechanisms, etc., bearing heavy loads and compensating for angular displacement, ensuring flexible component movement and accurate positioning.

Installation specifications: The mounting surface should be clean and free of burrs and rust to ensure good spherical contact. Avoid impurities affecting the self-aligning function and accelerating wear.

Use a dedicated press to press smoothly in; do not strike the spherical surface to prevent deformation or surface damage. After installation, apply the appropriate grease for the operating conditions to ensure initial lubrication.

Use with dustproof seals to prevent dust and moisture intrusion, protecting the spherical contact surface.

Maintenance Recommendations:

Check bearing clearance, abnormal noise, and lubrication condition every 500-1000 working hours. Replenish or replace grease as needed to prevent dry friction.

Replace bearings immediately if spherical wear, excessive clearance, or surface peeling is found to prevent cascading failures. Store spare parts in sealed containers to prevent moisture and corrosion.
