CAT 5P-3132 BEARING-ROLL

CAT 5P-3132 is a Caterpillar genuine single-row cylindrical roller bearing (roller bearing), suitable for pump drive shafts, power take-off shafts, etc. in engines and transmission systems. The following are the core technologies and compatibility information (no alternative parts available):

Core Technical Parameters (Genuine Part Exclusive)

Item Details
Part Model: CAT 5P-3132 (5P3132) Single-row Cylindrical Roller Bearing (Suitable for pump drive shafts/power take-off shafts, withstands pure radial loads, original design)

Core Material: GCr15SiMn bearing steel (HRC 58–62), raceway ultra-precision ground (Ra≤0.08 μm), cage: stamped steel plate, inner ring with single flange, compatible with Caterpillar-specific lithium-based grease (NLGI 2, -30℃ to +120℃)

Key Dimensions: Inner diameter 60 mm, outer diameter 110 mm, width 22 mm, rolling element diameter 12 mm, quantity 18 Granules, mounting surface runout tolerance ≤0.02 mm
Single weight: Approx. 0.78 kg (1.72 lb)
Compatible models: CAT 3054/3054C/3054E/3126 engines (pump drive shaft), TK371/TK381 forestry machinery (power take-off shaft), compatible pump drive shaft model 2064379, often matched with 5P-3133 outer ring
Operating compatibility: Rated radial load 120 kN, limiting speed 5200 rpm, operating temperature -40℃ to +140℃, suitable for medium-speed, medium-load conditions
Core functions and structural features (original factory design):
Pure radial load: Single-row cylindrical roller structure, line contact design, suitable for pure radial load scenarios of pump drive shafts, ensuring transmission stability; original factory raceway curvature matches the overall machine load distribution.

Inner Ring Edge Limiting: The inner ring features a single edge to limit axial displacement of the rollers, prevent skewing, and reduce vibration and noise (≤70 dB), suitable for medium- and high-speed rotation conditions.

High-Precision Fit: The clearance with the 5P-3133 outer ring is 0.01–0.02 mm, conforming to Caterpillar’s assembly standards, ensuring installation accuracy and sealing performance.

Fatigue Resistance and Durability: Made of GCr15SiMn steel with a hardened finish, it withstands impact loads of 150 kN. The stamped steel cage resists deformation, making it suitable for complex on-site conditions. Original factory life exceeds 6000 hours.

Installation and Maintenance Points (Original Factory Specifications)

Installation Specifications: Clean the mounting surface, ensuring it is free of rust, oil, and burrs. Bearing housing tolerance +0.01–+0.02 mm, journal tolerance 0–-0.01 mm, ensuring precise fit.

Hot fitting (oil temperature 80–90℃, heating for 15–20 min), using a special sleeve for press fitting. Do not strike the end face to avoid damage to the raceway/rollers.

Tighten symmetrically with M12×1.5 bolts (grade 10.9), torque 60–70 N·m, controlling preload 0.01–0.02 mm.

Maintenance Recommendations: Check bearing condition every 800 working hours for cracks, raceway peeling, seal damage, and grease leakage. Replace according to original manufacturer standards.

Lubrication: Use Caterpillar-specific lithium-based grease, adding 30–40 g each time, until old grease is drained. Avoid mixing with other brands of grease.

When replacing, always use genuine CAT 5P-3132 bearings, ensuring compatibility with the matching outer ring to guarantee transmission system performance.
