30310 7310E 30310JR Chrome Steel 50*110*29mm Single Row Cone and Cup Tapered Roller Bearings
Engineered to international standards (ISO 355, DIN 720) with P6-level precision, these single row cone-and-cup bearings align with standard mid-size shaft and housing dimensions. The 50mm inner diameter (tolerance: -0.018/0.000mm) fits common shafts in industrial compressors, heavy power tools, and automotive drivetrain components, while the 110mm outer diameter and 29mm width ensure seamless integration into conveyors, small industrial pumps, and machinery housings . CNC machining and laser calibration keep critical dimensions within ±0.005mm, eliminating fit gaps during installation and avoiding misalignment-induced friction that wastes 35-45% of equipment efficiency.
