CAT 472-8019 BEARING-SLV-GD

CAT 472-8019 (4728019) YM is a Caterpillar genuine general-purpose sleeve bearing used for bushing positioning and rotational support in chassis, transmissions, or hydraulic systems. It is suitable for low-to-medium speed and light-to-medium load applications. The following is precise original part information:

Core Parameters and Compatibility Information

Item Details
Part Model: CAT 472-8019 YM Genuine Sleeve Bearing, weighing approximately 0.42 kg (0.926 lb), suitable for low-to-medium speed and light-to-medium load bushing positioning and rotational support applications. It reduces friction between the shaft and bore, and is compatible with shaft end structures with a pin diameter of approximately 50 mm (Cat®…).

Core Material: High-quality carbon steel base material with a hardened surface treatment to improve wear resistance and fatigue strength. Suitable for dusty and humid environments, preventing rust-induced jamming or wear. Structural strength and durability meet general operating requirements (Cat®…).

Key Dimensions: Inner diameter approximately 50.00 mm 1.969 in diameter, outer diameter approx. 60.00 mm (2.362 in), total length approx. 45.00 mm (1.772 in), inner diameter tolerance H7, interference fit with shaft, interference amount 0.01-0.03 mm, suitable for mounting structures with standard shaft diameter of 50 mm.

Structural Features: Cylindrical flangeless design, smooth inner hole, burr-free edges, effectively reducing friction between shaft and hole, ensuring shaft rotational accuracy. Compact structure, easy installation, suitable for low-to-medium speed and light-to-medium load conditions.

Compatible Models: Suitable for chassis suspension, gearbox output shaft, or hydraulic cylinders of CAT D6R/D6T bulldozers, 950M/966M loaders, and 140M graders, used for bushing positioning and rotational support, suitable for low-to-medium speed and light-to-medium load conditions.

Accessories: Compatible with CAT 5P-3510 Bearing puller, 4C-9520 mounting punch, used with CAT 6D-4189/356-5975 bearing retainer. Installation requires a tight fit with the shaft end for precise positioning.

Core Functions and Installation Points:

Friction Reduction Support: Reduces relative friction between the shaft and the hole, minimizing component wear, ensuring shaft rotational accuracy, suitable for low-to-medium speed, light-to-medium load rotation/oscillation conditions, and extending component lifespan.

Installation Specifications:
Clean the mounting hole, sleeve bearing, and shaft surface, checking for deformation, cracks, rust, or other damage to the bearing.

Use cold pressing to press the bearing into the mounting hole, ensuring coaxiality with the shaft. After pressing, check that the bearing rotates freely without jamming or abnormal noise.

Tighten the relevant fasteners to the torque specified in the machine manual (typically 10-15 N·m). After installation, ensure no axial movement or clearance, guaranteeing stable operation.

Maintenance Recommendations: Inspect bearings for wear, corrosion, and loosening every 500-700 working hours. Replace with genuine parts immediately if wear exceeds 0.2 mm or if corrosion or deformation is observed.

Use only CAT 472-8019 YM genuine sleeve bearings to avoid increased friction, accelerated shaft and bore wear, or component failure due to incompatible dimensions/materials.
