The CAT 4F-9413 (4F9413) is a Caterpillar original single-row cylindrical roller bearing with a cage, suitable for high-speed, medium-load rotating components such as gearboxes and transfer cases. The following is precise information (without additional description):
Core Parameters and Information
Item Details
Part Model: CAT 4F-9413 Single-Row Cylindrical Roller Bearing
Part Type: Single-row cylindrical roller bearing with cage, bearing only radial loads, suitable for high-speed, medium-load conditions
Material: High-carbon chromium bearing steel (GCr15), roller hardness HRC 60-64, inner/outer ring hardness HRC 58-62, cage is made of high-quality low-carbon steel sheet by stamping
Key Dimensions: Inner diameter 30.00 mm (1.1811 in), outer diameter 55.00 mm (2.1654 in), width 19.00 mm (0.7480 in), roller diameter 6.00 mm, 12 pieces, radial clearance C3 group (0.012-0.028 mm)
Structural Features: Open structure, no sealing ring, inner ring with flange, outer ring without flange, suitable for oil lubrication, cage guide rollers to reduce friction and wear.
Compatible Structures: Gearbox intermediate shaft bearing, transfer case output shaft bearing, hydraulic pump drive shaft bearing, steering gear shaft bearing
Applicable Operating Conditions: Suitable for -40℃ to 120℃, suitable for shaft speed ≤6000 rpm, radial load ≤22 kN, suitable for continuous rotation conditions.
Compatible Machines and Assemblies:
Engine: CAT C7.1, C9.3 (accessory drive shaft bearing, water pump bearing)
Loader: CAT 950M, 962M (gearbox second shaft bearing, boom hydraulic pump bearing)
Excavator: CAT 320GC, 323GC (swing motor bearing, boom cylinder control valve bearing)
Road Roller: CAT CS66B, CS76B (Vibration Pump Drive Shaft Bearing, Steering Pump Bearing)
Compatible Assemblies: CAT 4F-9413 Gearbox Intermediate Shaft Assembly, 306-2145 Hydraulic Pump Assembly, 246-5211 Engine Fan Assembly
Installation and Fitting Points
Shaft Diameter: 30.00+0.015/-0.000 mm. The bearing inner ring should have an interference fit with the shaft diameter (interference 0.008-0.015 mm) to prevent relative rotation.
Mounting Hole Diameter: 55.00+0.018/-0.000 mm. The bearing outer ring should have a clearance fit with the mounting hole (clearance 0.008-0.018 mm) for easy installation and heat dissipation.
Use a dedicated bearing installation tool (inner ring press sleeve) to press the bearing in smoothly. Do not directly hammer the outer ring or rollers to avoid damaging the cage and rollers.
Before installation, clean the shaft, mounting holes, and bearings, ensuring there are no burrs, oil stains, or rust. Inspect the bearings for any jamming, abnormal noises, or missing rollers.
After installation, the bearing end face should be flush with the mounting hole end face, with no axial movement, smooth rotation, and unobstructed lubrication.
