PRODUCT DESCRIPTION
High-Grade Bearing Steel & Precision Manufacturing
This 370309Y bearing for FAST gearbox is produced with high chromium bearing steel, processed by precision grinding and strict heat treatment. It maintains stable hardness and structural strength under high speed and heavy load working conditions. The smooth raceway reduces rolling friction effectively, supporting steady power transfer for FAST gearbox. It is standard FAST transmission part for truck gearbox overhaul and component replacement.
Reduce Gearbox Noise & Prevent Premature Failure
Worn or inferior gearbox bearings will cause abnormal noise, stuck shifting and even gearbox breakdown on heavy trucks. Our 370309Y bearing features consistent clearance control and excellent fatigue resistance. It absorbs alternating radial loads during long-haul driving, avoiding excessive vibration inside FAST Gearbox Assy. This part fixes common transmission faults and protects other expensive gearbox components from secondary damage.
