CAT 360-2327 BEARING-SLV-GD

CAT 360-2327 is a Caterpillar genuine YM straight sleeve bearing, used for the rotational support of articulated joints, connecting rods, or pins in construction machinery. It is suitable for low-to-medium speed, medium-load rotating parts in graders, backhoe loaders, and other models. The following is precise original part information for Cat®…: Core Parameters and Compatibility Information

Item Details
Part Model: CAT 360-2327 (3602327) Genuine YM Straight Sleeve Bearing, weighing approximately 0.32 kg (0.71 lb), suitable for articulated/connecting rod support positions with a pin diameter of 50 mm, used for load bearing and friction reduction in rotational motion.

Core Materials: Steel back + bronze alloy + PTFE filler layer. The steel back ensures structural strength, the bronze layer bears heat and conducts heat, and the PTFE layer reduces the coefficient of friction. Suitable for outdoor dusty and vibrating conditions, wear-resistant, impact-resistant, and with excellent thermal conductivity.

Key Dimensions: Inner diameter approximately 50.00 mm 1.969 in diameter, outer diameter approximately 55.00 mm (2.165 in), total length approximately 38.10 mm (1.500 in), straight flangeless structure, smooth inner bore, interference fit press-fit mounting hole, compatible with 50 mm pins, mounting hole diameter 55 mm.

Structural Features: Straight cylindrical integral structure, precision machined inner and outer circles, surface roughness Ra≤0.8μm, interference fit installation without loosening, suitable for continuous rotation/oscillation conditions, wears synchronously with the pin, ensuring fitting accuracy.

Compatible Models: Compatible with CAT 140K/160K graders, 420F2/430F2 backhoe loaders, 908M/909M mini loaders for articulation pins, connecting rod pins, or working device connecting pins; commonly used with 380-7558 YM shafts, 585-1503 YM sleeve bearings, etc.

Accessories: Compatible with CAT 4C-9520 mounting punch, 5P-3510 bearing puller, mounting hole tolerance H7, interference fit 0.03-0.06 mm, cold press into place to avoid heating deformation.

Core Functions and Installation Points

Load Bearing and Friction Reduction: Supports the pin and reduces friction between it and the mounting hole, reducing component wear and ensuring flexible movement; evenly distributes the load to prevent localized stress concentration leading to deformation and damage.

Installation Specifications
Clean the mounting hole, bearing surface, and O-ring groove. Check for cracks in the bearing and aging damage to the O-ring.

Cold press the pin into the mounting hole using a special punch, ensuring the end face is flush with the mounting hole plane without tilting.

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

Maintenance Recommendations: Inspect bearing wear, clearance, and surface condition every 600-800 operating hours. Replace with genuine parts immediately if clearance > 0.10 mm, surface peeling, or cracks are found.

Use only genuine CAT 360-2327 parts to avoid material/size mismatches that could lead to accelerated wear of the pins and mounting holes, jamming, or component failure.
