Core Parameters and Information
Item Details
Part Model: CAT 006-0846 (006846) Bearing
Part Type: Single-row tapered roller bearing, separable structure (inner ring + roller assembly can be separated from outer ring), withstands radial + unidirectional axial combined loads
Material: Inner ring / Outer ring / Rollers: Chromium bearing steel (GCr15), Cage: Stamped steel plate, hardness HRC60-64
Key Dimensions: Inner diameter 42 mm, outer diameter 76 mm, width 39 mm, cone angle 14°, number of rollers 10, roller diameter 14 mm
Structural Features: Outer ring with retaining groove, can be equipped with retaining ring; inner ring with cage and roller assembly for easy assembly and maintenance
Surface Treatment: Rollers and raceways are ultra-precision ground, surface roughness… Ra≤0.4μm, outer ring blackened for rust prevention
Matching: Inner ring interference fit with shaft (k5), outer ring transition fit with bearing housing (J7)
Rated Load: Radial rated dynamic load 62 kN, radial rated static load 75 kN, axial rated dynamic load 25 kN, axial rated static load 42 kN
Limiting Speed: Grease lubrication 4500 r/min, oil lubrication 5800 r/min
Operating Temperature: -40℃ ～ +120℃
Weight: 0.72 kg
Compatible Models and Assemblies:
Agricultural Machinery: Challenger MTC735, MTC745, MTC755, MTC765 (transmission system, wheel axle bearings)
Construction Machinery: CAT mini loaders, skid steer loaders (drive axle, gearbox output shaft bearings)
Matching Parts: 006-0846 Bearings, retaining rings, lock nuts, bearing housings, seals, grease fitting nozzles
Installation and Fitting Points:
Clean the journal and bearing housing bore, removing burrs and oil. Journal roughness Ra≤0.8μm, bearing housing bore roughness Ra≤1.6μm.
Inner ring installation: heat (oil temperature 80-100℃). Press the outer ring smoothly into the bearing housing using a press; do not strike the bearing end face.
Install the retaining ring to secure the outer ring and prevent axial movement. Tighten the lock nut to the specified torque.
Post-installation inspection: Bearing end face runout ≤0.05 mm, radial clearance 0.012-0.025 mm, no jamming or abnormal noise.
Add lithium-based grease to ensure adequate bearing lubrication.
