22220CA/W33 Spherical Roller Bearing, Self-aligning, Heavy Load, Long Service Life Roller Bearings For Mining Machinery

Model 22220CA/W33 spherical roller bearing is double-row self-aligning roller bearing with brass CA cage and W33 lubrication structure. It can bear large radial load and moderate bidirectional axial load at the same time.

• Excellent Self-aligning Performance

  Allow shaft deflection & mounting misalignment up to 1.5°, avoid bearing stuck and premature damage.

• Super Heavy Load Bearing Capacity

  Double symmetrical spherical rollers evenly distribute pressure, suitable for continuous heavy-duty working condition.

• Convenient Lubrication & Longer Lifespan

  Built-in W33 circumferential oil groove + 3 oil injection holes, uniform grease/oil filling, reduce friction loss and wear.

• High Strength Brass CA Cage

  Machined brass cage owns strong rigidity, anti-deformation under high speed and heavy impact load.

• Wear-resistant GCr15 Steel Material

  Whole bearing ring and rollers adopt quenched chrome steel, high hardness, anti-corrosion and anti-fatigue.
