Achieve Frictionless Rotation, Prevent Component Lockup. Worn bearing causes abnormal noise, shaft shaking and belt damage. This double-sealed bearing supports high-speed stable operation, reducing friction loss and avoiding drive system stuck failure for Volvo engineering machinery.
High-carbon Chrome Bearing Steel Overall quenching treatment, anti-fatigue and anti-peeling under long high-speed rotation.
Super-finished Raceway Ultra-smooth rolling surface, low friction torque and quiet running performance.
Extreme Pressure Synthetic Grease Stable lubrication under high temperature, effectively slow down metal wear.
Dual-lip Rubber Seals Lock internal grease, isolate dust and water to extend service life greatly.

Bearing quality directly decides drive system stability. Inferior lubrication and poor sealing easily lead to sudden locking shutdown. Machinery spare parts dealers and maintenance workshops recommend stocking genuine 996518 bearings. Match with drive belts, shaft collars and oil seals to complete accessory overhaul parts set.
Obvious whining and grinding noise inside engine compartment, sound changes with rotating speed
Pulley shakes abnormally by hand pushing, excessive radial clearance and loose assembly
Bearing outer ring discoloration by high heat, grease leakage and surrounding dirt accumulation
All models for compatibility reference only. High precision sealed bearing ensures smooth frictionless rotation, effectively avoids accessory locking and belt damage, guarantees steady running of construction machinery.
