SKF SKF Explorer Series Ball Bearing, 90mm Inside Diameter, 160mm Outside Diameter - 7218 BECBJ


This ball bearing is designed to support axial and radial loads in rotating equipment within automation and mechanical systems. It is a single-row angular contact type with a parallel bore and an open-end configuration, intended for applications requiring directional load handling and routine maintenance access.

Features & Benefits


• 40° contact angle improves axial load accommodation and stiffness
• 116 kN dynamic load rating extends service life under cyclic loads
• 104 kN static load rating resists deformation under high static forces
• 5,000 r/min limiting speed suits high-speed rotating assemblies

**Applications**


• Suitable for spindle supports in CNC machinery
• Ideal for high-speed motors in automation lines
• Used with gearboxes requiring axial load support
• Can be used for precision rotary encoders and servomotors

What material is used for the rolling elements and why does it matter?


The balls are steel, offering high hardness and wear resistance for sustained contact performance under load.

How does the bore design affect installation?


The parallel bore permits straightforward mounting on cylindrical shafts and compatibility with standard journal fits.

What maintenance considerations arise from the open-end design?


The open end allows easier inspection and re-lubrication access but requires appropriate Seals if contaminants are present.

How does the cage material influence thermal and mechanical behaviour?


The steel sheet-metal cage provides dimensional stability at elevated running speeds and contributes to controlled ball spacing under centrifugal forces.
