CAT 583-3195 Double Row Spherical Roller Bearing

CAT 583-3195 is a Caterpillar genuine single-row deep groove ball bearing (GD bearing, suitable for G-series bulldozers/loaders, etc.), used in gearbox input shafts, hydraulic pump drive ends, etc. The following is raw data and does not include replacement parts information (Cat® Parts).

Core Technical Parameters (Raw Data)

Item Details
Basic Attributes Model 583-3195, Type Single Row Deep Groove Ball Bearing, Material Chromium-Molybdenum Alloy Steel (Inner Ring / Outer Ring / Balls), Cage is Stamped Steel Plate, Seal Type Non-Contact Rubber Seal (Double-Sided), Weight 0.98 kg, Operating Temperature -40℃ to +120℃, Lubrication Method Grease Lubrication (Recommended Cat DEO-ULS 2), Applicable Speed ​​≤5000 rpm

Key Dimensions Inner Diameter 75 mm (2.953 in), Outer Diameter 130 mm (5.118 in), Width 25 mm (0.984 in), Chamfer Size r1.5 mm, Radial Clearance C3 Group (0.012-0.028 mm), Inner Diameter Tolerance +0.015/-0 mm, Outer Diameter Tolerance 0/-0.015 mm, Width Tolerance ±0.15 mm, Ball Diameter 12.7 mm mm, 18 steel balls

Suitable Models and Parts: Compatible with the front end of the gearbox input shaft of Cat D8G/D8R bulldozers, the hydraulic pump drive shaft of 980G loaders, and the fan pulley shaft of C15 engines. One piece is used at each location. It primarily bears radial loads and secondarily bears slight bidirectional axial loads, limiting radial runout and axial movement of components.

Performance Parameters: Radial rated dynamic load Cr=60.8 kN, radial rated static load C0r=38.5 kN, axial rated dynamic load Ca=14.2 kN, axial rated static load C0a=10.5 kN, limiting speed (grease lubrication) 4500 rpm, limiting speed (oil lubrication) 5600 rpm, hardness HRC 58-62 (inner and outer rings/steel balls), cage hardness HB 180-220

Structural and Performance Advantages: Chromium-molybdenum alloy steel material: high hardness and wear resistance, suitable for heavy-duty and vibration conditions in engineering machinery, with a long fatigue life.

Double-sided sealing design: Effectively prevents dust and moisture from entering the bearing, reducing grease leakage and extending maintenance intervals.

C3 clearance configuration: Adapts to thermal expansion under high-temperature conditions, preventing bearing seizure and ensuring smooth operation.

Stamped steel cage: High strength and lightweight, suitable for high-speed operation, reducing the impact of centrifugal force, and minimizing noise and vibration.

Installation and maintenance points (raw data)

Installation: Clean the journal and bearing housing bore. Install the inner ring using the hot fitting method (oil temperature 80-100℃) and the outer ring using the cold fitting method. Ensure the bearing end face fits snugly against the shaft shoulder/seat shoulder (clearance ≤0.05 mm). After installation, rotate by hand without jamming; radial runout ≤0.03 mm.

Maintenance: Check bearing temperature (≤80℃), noise (≤75 dB), and grease condition every 3000 hours. Replenish grease every 6000 hours (1/3-1/2 of the bearing cavity volume). Replace immediately if abnormal noise, overheating, or seal damage occurs. Troubleshooting: For abnormal bearing noise, check the condition of the grease and steel balls; for overheating, check the clearance and installation accuracy; for damaged seals, replace the bearing and check the protective environment; for severe wear (radial clearance > 0.05 mm), replace immediately.
