32230 7530E 32230JR Chrome Steel 150*270*77mm Single Row Cone and Cup Tapered Roller Bearings

32230 7530E 32230JR Chrome Steel 150*270*77mm Single Row Cone and Cup Tapered Roller Bearings

Engineered to strict international standards (ISO 355, DIN 720) with P6-level precision, these single row cone-and-cup bearings align seamlessly with heavy-duty shaft and housing dimensions:
150mm ID (tolerance: -0.030/0.000mm): Fits medium-to-large shafts in 40-60kW electric motors, heavy-duty industrial tool spindles (e.g., large drilling machines, vertical milling equipment), and commercial/agricultural vehicle components (e.g., heavy-duty fan shafts, industrial pump shafts, or transmission auxiliaries in farm tractors or small excavators).
270mm OD + 77mm width: Integrates smoothly into heavy-duty machinery housings, large industrial pumps, bulk-material conveyors, and medium-duty gearboxes—ideal for applications where space is constrained but load demands are substantial (e.g., small-scale manufacturing lines for heavy parts, agricultural harvesting equipment, or workshop heavy machinery).
CNC machining and laser calibration keep critical dimensions within ±0.005mm, eliminating fit gaps that cause 82-92% efficiency loss in misaligned heavy-duty systems. Whether replacing a 32230 in an industrial milling machine or a 32230JR in a KOYO-equipped agricultural harvester, no modifications to existing setups are required.
