CAT 544-4760 BEARING

CAT 544-4760 is a genuine Caterpillar single-row cylindrical roller bearing, suitable for medium-duty, low-speed, heavy-duty components such as gearboxes and differentials in medium-sized construction machinery. The following are precise original specifications and application information, excluding replacement Cat parts.

Core Technical Parameters

Item Details
Part Model: CAT 544-4760 (Single Row Cylindrical Roller Bearing)

Material: Inner ring/outer ring/roller are made of high-carbon chromium bearing steel (AISI 52100), hardness 60–64 HRC; cage is made of stamped steel plate, galvanized for corrosion protection.

Key Dimensions: Inner diameter 60 mm (2.362 in), outer diameter 95 mm (3.740 in), width 24 mm (0.945 in), chamfer radius r=2 mm

Rated Parameters: Radial dynamic load rating 68.0 kN, radial static load rating 72.0 kN; operating temperature -30℃ ~ +120℃, suitable linear speed ≤ 5 m/s

Single Weight: Approx. 0.65 kg (1.433 lbs)

Tolerance Standards: Inner diameter tolerance P6, outer diameter tolerance P6, radial clearance C3, radial runout ≤ 0.015 mm, surface roughness Ra ≤ 0.4 μm

Surface Treatment: Inner and outer ring surfaces are oxidized and blackened, roller surfaces are polished, improving fatigue resistance and wear resistance, suitable for oil lubrication conditions.

Structure and Core Characteristics

Single-row flangeless design: No outer ring flange, suitable for pure radial load conditions, compact structure, easy to install in narrow spaces such as gearbox planetary carriers and differential housings (Cat®…).

High-precision manufacturing: P6 tolerance and C3 clearance ensure stability at low and medium speeds, reduce vibration and noise, suitable for the transmission accuracy requirements of medium-sized equipment.

Stamped steel cage: Lightweight cage design ensures roller positioning accuracy, suitable for low and medium speed heavy load conditions, extending bearing life (Cat®…).

High adaptability: 24 mm width design balances load-bearing capacity and lightweight, suitable for gearbox output shafts, differential input shafts, etc. in excavators and loaders.

Compatible Models and Application Scenarios

Compatible Equipment: CAT 326GC/330GC excavators, 950M/962M loaders, 430F2 backhoe loaders, and other medium-sized equipment.

Core Applications: Used for radial support in parts such as the gearbox planetary carrier, differential housing, and drive shaft support. It absorbs vibration, transmits loads, and ensures flexible component operation. Suitable for medium to heavy-duty operations in infrastructure, mining, and other similar applications for Cat engines.
