7214BM Single Row 40° Angular Contact Ball Bearing Solid Machined Brass Cage 70x125x24mm Machine Tool Equipment

The 7214BM single row angular contact ball bearing is designed for machine tool and heavy transmission equipment, featuring 40° large contact angle and solid brass cage to bear combined radial and heavy unidirectional axial load.

It is widely used in speed reducers, main shafts and drive motors where high axial rigidity and stable high-speed operation are required.

• 40° large contact angle structure greatly improves axial bearing capacity and overall axial rigidity
• Solid machined brass cage resists high temperature and deformation, stable performance under continuous high speed
• Can only bear unidirectional axial force, matched in DB/DF/DT duplex arrangement for bidirectional thrust load
• Superfinished raceway and steel balls reduce vibration and running noise for precision equipment operation
• High hardness heat-treated steel delivers outstanding wear resistance under heavy cyclic composite load
• Custom precision grades (P0/P5/P4) and clearance options can be produced for different working conditions

This bearing is widely used in:

• CNC machine tool spindle support and feed shaft rotary assemblies
• Industrial heavy speed reducers and medium-large drive motors
• Pump, fan and compressor high-speed rotary supporting parts
• General metallurgical machinery and packaging heavy transmission equipment

• 25+ years experience in angular contact ball bearing manufacturing
• Exported to many countries worldwide
• Rich experience in OEM & bulk custom bearing projects
• Strict full-process rigidity and rotation performance inspection before shipment
• Fast professional technical response within 24 hours
• Stable mass supply for long-term machine tool and machinery factory cooperation

• Raw material composition and hardness inspection
• Precision superfinishing grinding for angular raceway and steel balls
• Standard quenching & tempering heat treatment control
• Axial rigidity test and clearance grouping classification inspection
• Full dimensional final inspection before delivery
