CAT 467-7102 BEARING

CAT 467-7102 is a Caterpillar genuine heavy-duty straight sleeve bearing, suitable for low-speed, heavy-load oscillating parts such as loaders, excavators’ booms, sticks, and cylinder pins. The following is pure raw data and does not include replacement parts information.

Core Technical Parameters (Raw Data)

Item Details
Basic Attributes
Model 467-7102, Type: Heavy-duty straight sleeve bearing, Material: Steel back + high-strength brass alloy (CuZn25Al5), Single weight: 1.56 kg, Applicable working conditions: low-speed heavy-load oscillation, impact load, Working temperature: -25℃ to +150℃, Rated bearing pressure: ≥240 MPa, Friction coefficient: ≤0.09 (oil lubrication), Matching pin diameter: φ50.8 mm, Used for boom pins, stick cylinder pins, rocker arm joints, and other rotating supports.

Key Dimensions (Metric / Imperial)
Inner diameter: 50.80 mm (2.000 in, tolerance +0.02/-0 mm), Outer diameter: 63.50 mm (2.500 in, tolerance +0.03/-0 mm), Length: 101.60 mm (4.000 in, tolerance ±0.1 mm), Wall thickness: 6.35 mm (0.250 in, tolerance ±0.02 mm), end face perpendicularity ≤0.02 mm, inner hole roughness Ra≤0.8 μm, suitable shaft diameter φ50.80-50.83 mm, installation interference 0.03-0.05 mm

Performance Parameters: Steel backing hardness HB 180-220, brass layer hardness HB 90-110, fatigue life ≥1.2×10⁶ cycles (200 MPa load), wear resistance ≥5000 hours (oil lubrication condition), installation pressure ≤120 kN, compatible with Cat HD EP 2 grease

Structure and Compatibility Characteristics: Composite material structure: The steel backing provides high-strength rigid support, and the brass alloy layer has excellent wear resistance and self-lubricating properties, which can reduce pin wear under low speed, heavy load, and impact conditions, and is suitable for joint parts without continuous lubrication.

Precise Size Fit: The oil-free/oil-groove design accommodates φ50.8 mm pins and φ63.5 mm mounting holes. An interference fit ensures secure installation without loosening. It precisely matches the original pins and mounting holes, requiring no additional machining.

Operating Conditions: Suitable for harsh operating conditions including open air, dust, and impact. The brass layer can accommodate small amounts of impurities, reducing the risk of jamming and extending component lifespan.

Installation and Maintenance Points (Original Data)

Installation: Clean the mounting holes, pins, and bearing surfaces (free from oil, rust, and burrs). Use cold-press installation (pressure ≤120 kN). After installation, the bearing end face should be flush with the mounting surface, without skewing. The pin should rotate freely without jamming. The clearance between the bearing and the mounting hole should be ≤0.01 mm.

Maintenance: Check lubrication every 500 hours and add Cat HD EP 2 grease. Regularly inspect bearing wear; replace when the inner diameter wear exceeds 0.15 mm. For long-term storage, apply rust-preventive oil and seal to prevent moisture.
