32022 200722E 32022R Chrome Steel 110*170*38mm Single Row Cone and Cup Tapered Roller Bearings

Built with GCr15/SAE 52100 high-carbon chrome steel—the gold standard for industrial bearings—these units undergo precision heat treatment to achieve HRC 58-62 hardness. This engineering delivers three key advantages for demanding environments:
Abrasion Resistance: Outperforms low-carbon steel by 250-260% in dusty settings (e.g., construction sites, metal forging shops), resisting wear from particulate matter.
Impact Toughness: Handles sudden load spikes (e.g., dropping heavy metal parts onto conveyors) without cracking, critical for heavy-manufacturing use.
Corrosion Resilience: When paired with optional treatments (hot-dip zinc plating, anti-corrosion oil), it withstands humidity in textile mills, industrial laundries, or outdoor irrigation systems.
Ideal for 7-30kW electric motor shafts and heavy gearboxes, they reduce long-term replacement costs by extending service life to 16,500-18,500 operating hours.
