CAT 361-1695 BEARING-SLV-GD

CAT 361-1695 is a Caterpillar genuine YM series 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 361-1695, Type YM series heavy-duty straight sleeve bearing, Material steel back + CuSn10Pb10 sintered bronze alloy, Single weight 0.78 kg, Applicable working conditions low-speed heavy-load oscillation, impact load, dusty conditions, Working temperature -30℃ to +140℃, Rated bearing pressure ≥220 MPa, Friction coefficient ≤0.08 (oil lubrication), Applicable pin diameter φ41.28 mm, Used for boom pins, stick cylinder pins, rocker arm joints, and other rotating supports.

Key Dimensions (Metric / Imperial)
Inner diameter 41.28 mm (1.625 in, tolerance +0.02/-0 mm), Outer diameter 50.80 mm (2.000 in, tolerance +0.03/-0 mm), Overall length 50.80 mm (2.000 in, tolerance… ±0.1 mm), wall thickness 4.76 mm (0.1875 in, tolerance ±0.02 mm), no oil holes/grooves, compatible mounting hole diameter φ50.80-50.83 mm, interference fit 0.03-0.05 mm

Performance Parameters: Steel backing tensile strength ≥500 MPa, bronze layer hardness HB 80-100, fatigue life ≥1.0×10⁶ cycles (180 MPa load), wear rate ≤0.01 mm/1000 hours (oil lubrication), installation pressure ≤100 kN, compatible with Cat HD EP 2 grease

Structure and Compatibility Characteristics: Composite structure: The steel backing provides rigid support, and the bronze alloy layer has self-lubricating and wear-resistant properties, suitable for low-speed, heavy-load joints without continuous lubrication, reducing wear on pins and bearings.

Precise Fit: The oil-free/oil-groove design accommodates φ41.28 mm pins and φ50.80 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 environments, dust, and impacts. The bronze 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 ≤100 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 400 hours and add Cat HD EP 2 grease. Regularly inspect bearing wear; replace when the inner diameter wear exceeds 0.12 mm. For long-term storage, apply rust-preventive oil and seal to prevent moisture.
