CAT 422-9526 BEARING-SLV-GD

CAT 422-9526 is a Caterpillar genuine YM series steel-backed copper-lead alloy sleeve bearing (shoulder sleeve), suitable for the connecting rod/boom hinge points of backhoe loaders such as the 422E/F2 and mini excavators. It is used to bear radial loads and reduce hinge friction. The following is precise original part information:

Core Technical Parameters
Item Details
Part Model: CAT 422-9526 (4229526) YM sleeve bearing, single weight approximately 0.85 kg (1.87 lb), suitable for low-speed oscillation and medium-to-heavy-load hinge support conditions in construction machinery

Core Material: Steel backing + CuPb24Sn4 copper-lead alloy anti-friction layer, steel backing thickness 3.0 mm, copper-lead alloy layer thickness 0.7-0.9 mm, tin-plated surface, suitable for vibration and impact conditions, wear-resistant and anti-galling

Key Dimensions: Inner diameter 50.8 mm (2.00 in), outer diameter 57.15 mm 2.25 in diameter, 50.8 mm (2.00 in) wide, with axial positioning groove, suitable for hinged installation with a pin diameter of 50.8 mm, integral oil-free self-lubricating structure.

Structural Features: Integral bimetallic structure, oil-free self-lubricating, suitable for frequent oscillation conditions; positioning groove prevents rotation, ensuring stable hinge operation and reducing wear between the pin and mounting hole.

Compatible Models: Compatible with CAT 422E/422F/422F2 backhoe loaders, 302.7D CR/303ECR mini excavators (boom/stick hinge point), 416E/420E loader linkage hinge point, etc.

Accessories: Compatible with pins with a diameter of 50.8 mm; matching installation tools: CAT 1U-7360 bearing puller, 2S-8359… When installing the sleeve, simultaneously check the roundness and coaxiality of the pin.

Core Functions and Installation Points
**Articulated Support Friction Reduction:** Used in articulated parts such as booms, sticks, and connecting rods to withstand radial loads. Suitable for low-to-medium speed, medium-to-heavy load, and frequent oscillation conditions in construction machinery, ensuring smooth operation.

Installation Specifications
Clean the mounting holes and bushing surfaces, removing oil and burrs. Check the compatibility of the mounting hole tolerance (H7) and bushing outer diameter tolerance (r6).

Cold-fitting press-in: Use a special sleeve to press evenly. Avoid forceful hammering to prevent deformation. Ensure the positioning groove is embedded in the mounting hole positioning structure.

After installation, check the radial clearance (0.04-0.09 mm) to ensure smooth and unobstructed operation.

Maintenance Recommendations
Check wear and clearance every 800 working hours. If the clearance exceeds 0.18 mm or there is surface peeling or scoring, immediately replace with an original factory bushing.

Use only genuine CAT 422-9526 parts to avoid premature hinge failure and pin damage caused by size/material mismatch.
