7206-B Single Row Open 40° Angular Contact Ball Bearing High Axial Rigidity 30x62x16mm Reducer Machine Tool Equipment

The 7206-B single row open angular contact ball bearing features a large 40° contact angle, designed to withstand combined radial and heavy one-way axial loads. It is widely matched to speed reducers, pump shafts and machine tool feed mechanisms requiring high axial rigidity and stable heavy-load operation.

• 40° large contact angle greatly enhances axial bearing capacity and overall axial rigidity against heavy thrust force
• Only bears unidirectional axial load; DB/DF/DT duplex pairing realizes bidirectional heavy axial support
• Open design allows convenient on-site grease replenishment for continuous long-hour heavy-duty operation
• Superfinished raceway and steel balls reduce vibration and noise to improve equipment running stability
• High hardness heat-treated bearing steel delivers excellent wear resistance under cyclic composite loads
• Optional upgrades: solid brass cage, P4/P5 high precision grade, C3 enlarged clearance for high-temperature use
• Standard metric ISO size, fully interchangeable with universal aftermarket replacement bearings

This high-rigidity 40° angular contact bearing is widely used in:

• Machine tool feed shafts, small spindle auxiliary support assemblies
• Industrial speed reducers, hydraulic pumps and compressor rotary shafts
• Small heavy-duty conveying machinery and packaging transmission equipment
• General metallurgical auxiliary equipment and agricultural power transmission parts

• 25+ years experience in 40° angular contact ball bearing manufacturing
• Exported to many countries worldwide
• Rich OEM bulk order experience for reducer and machine tool bearings
• Strict full-process rigidity, rotation noise and dimensional tolerance inspection before shipment
• Fast professional technical response within 24 hours
• Stable mass supply for long-term transmission and machine tool factory cooperation
