CAT 364-5266 BEARING-SLV-GD

CAT 364-5266 (3645266) is a Caterpillar genuine YM general-purpose straight sleeve bearing, suitable for medium to light loads and low to medium speed oscillating/rotating applications with articulated/pin supports. The following is precise original part information for Cat®…: Core Parameters and Compatibility Information

Item Details
Part Model: CAT 364-5266 Genuine YM straight general-purpose sleeve bearing, weighing approximately 0.38 kg (0.84 lb), suitable for medium to light load articulated positions with a pin diameter of 50 mm, used to reduce friction between the pin and the mounting hole, supporting medium to light loads.

Core Materials: Steel back + bronze alloy + graphite lubrication insert. The steel back ensures structural strength, the bronze layer provides thermal conductivity, and the graphite layer is self-lubricating. Suitable for medium to light loads and low speed oscillating applications, wear-resistant and impact-resistant, suitable for outdoor dusty environments.

Key Dimensions: Inner diameter approximately 50.00 mm 1.969 in diameter, outer diameter approx. 55.00 mm (2.165 in), total length approx. 45.00 mm (1.772 in), straight flangeless structure, smooth inner bore, interference fit press-fit mounting hole.

Structural Features: Straight cylindrical integral structure, precision machined inner and outer circles, surface roughness Ra≤0.8μm, interference fit mounting, suitable for continuous oscillating/rotating conditions, ensuring fitting accuracy and reducing maintenance frequency.

Compatible Models: Compatible with CAT 320D/320E excavators, 950H/950K loaders, 120M/140M grader booms, sticks, or connecting rod hinge pins, for medium to light load, low utilization conditions.

Accessories: Compatible with CAT 4C-9520 mounting punch, 5P-3510 bearing puller, mounting hole tolerance H7, interference fit 0.02-0.05 mm. mm, cold-pressed into place to avoid heating deformation

Core Functions and Installation Points

Friction Reduction and Load Bearing: Supports the pin and reduces friction, minimizes component wear, and ensures flexible movement; evenly distributes light to medium loads, preventing localized stress concentration that could lead to deformation and damage; suitable for light to medium loads and low to medium speeds.

Installation Specifications
Clean the mounting hole and bearing surface, and check the bearing for cracks and rust damage.

Use a special punch to cold-press the pin into the mounting hole, ensuring the end face is flush with the mounting hole plane and not tilted.

After installation, check the clearance between the pin and bearing (0.01-0.03 mm). Ensure smooth rotation without jamming or abnormal noise. Tighten the relevant fasteners according to the model manual (usually 10-15 N·m).

Maintenance Recommendations
Check bearing wear, clearance, and surface condition every 500-700 working hours. If the clearance is >0.10 mm, or if there is surface peeling or cracks, replace immediately with an original part.

Use only genuine CAT 364-5266 parts to avoid material/size mismatch that could lead to increased wear on the pins and mounting holes, jamming, or component failure.
