Structural Features Double-row symmetrical roller bearings, stamped steel cage, double-sided contact seal (2RS), pre-filled lithium-based grease, radial clearance C3. Fit: Interference fit with shaft (0.012-0.020mm), clearance fit with bearing housing (0-0.015mm). Operating temperature: -30℃ to +120℃. Lubrication requirements: Pre-lubricated seal type, maintenance-free for life (check seal condition every 2000 hours under harsh conditions). Rated load: Dynamic rated load Cr: 180.0kN, Static rated load Cor: 180.0kN, Limiting speed (grease lubrication): 3200rpm. Compatible models and assemblies: Loaders: CAT 980M, 982M (drive axle differential support). Excavators: CAT 374F, 390F (slewing bearing reduction gearbox input shaft). Graders: CAT… 16M3, 18M3 (Drive Axle Main Reducer)
Matching Parts: 536-7892 Bearing, Bearing Housing (536-7893), Elastic Retaining Ring (8T-4125), Sealing Gasket (123-4567)
Installation and Fitting Points:
Clean the journal and bearing housing bore, ensuring no burrs or rust. Journal roughness Ra≤0.8μm, bearing housing bore roughness Ra≤1.6μm.
Cold press fitting, pressure ≤40kN. Apply force evenly to the inner ring end face using a special tool. Do not strike the outer ring or sealing ring.
After installation, check radial clearance: 0.025-0.035mm, end face runout ≤0.02mm, and rotation without jamming or abnormal noise.
After installation, confirm that the bearing outer ring fits snugly against the bearing housing bore, and there is no gap between the shaft shoulder and the inner ring end face.
