CAT 585-1503 BEARING-SLV-GD

CAT 585-1503 is a Caterpillar genuine YM sleeve bearing (straight sleeve), suitable for articulation joints, connecting rods, or pin rotation support positions in construction machinery. It is used to reduce friction, bear load, and ensure component positioning. The following is precise original part information:

Core Parameters and Compatibility Information

Item Details
Part Model: CAT 585-1503 (5851503) Genuine YM Straight Sleeve Bearing, weighing approximately 0.28 kg (0.62 lb). Suitable for articulation pins, connecting rod pins, or working device connection pin support positions in graders, backhoe loaders, etc., used for load support and friction reduction in rotating/oscillating parts.

Core Materials: Steel backing + bronze alloy + PTFE filler layer. The steel backing ensures structural strength, the bronze layer provides load-bearing capacity and thermal conductivity, and the PTFE filler layer reduces the coefficient of friction. Suitable for low-to-medium speed and medium-to-high load conditions. Excellent wear resistance, impact resistance, and thermal conductivity, suitable for outdoor dusty and vibrating conditions.

Key Dimensions Inner diameter approximately 45.00 mm (1.772 in), outer diameter approximately 50.00 mm (1.969 in), total length approximately 25.40 mm (1.000 in), straight flangeless structure, smooth inner hole without oil groove (partially suitable for pre-lubricated or oil bath lubrication conditions), interference fit press-fit mounting hole, suitable for pin diameter 45 mm, mounting hole diameter 50 mm, length 25.4 mm

Structural Features: Straight cylindrical integral structure, inner and outer circles are precision machined, surface roughness Ra≤0.8μm, interference fit installation, no risk of loosening, suitable for continuous rotation, oscillation or reciprocating motion conditions, wears synchronously with the pin, ensuring long-term fit accuracy.

Compatible Models: Compatible with CAT 140K/160K grader articulation pins, 420F2/430F2 excavator loader boom linkage pins, 908M/909M mini loader bucket pins, etc., often used with… Used in conjunction with 380-7558 YM shafts, 585-0415 YM sleeve bearings, etc., for multi-axis linkage articulated and connecting rod mechanisms.

Matching components: Compatible with CAT 4C-9520 mounting punch and 5P-3510 bearing puller. Installation requires matching mounting hole tolerance (H7), interference fit 0.03-0.06 mm, clean, burr-free surfaces, cold-pressed into place to avoid heating deformation.

Core Functions and Installation Points:

Load Support and Friction Reduction: Supports the pin and reduces friction between it and the mounting hole, reducing component wear, ensuring flexible movement, and evenly distributing load to prevent deformation or damage caused by localized stress concentration.

Installation Specifications:
Clean the mounting hole and bearing surface, removing oil, carbon deposits, and burrs. Check the interference fit.

Use a special punch to cold-press the bearing into the mounting hole, 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) to ensure smooth, unobstructed movement and no abnormal noise.

Maintenance Recommendations: Check bearing wear, clearance, and surface condition every 800-1000 working hours. Replace with genuine parts immediately if excessive clearance (>0.10 mm), surface peeling, or cracks are found.

Use only genuine CAT 585-1503 parts to avoid accelerated wear, jamming, or component failure caused by material/size mismatch.
