2218-2RS Self-Aligning Ball Bearing 90x160x40mm

Contact Us


Quantity:


Self-aligning ball bearings are designed to accommodate misalignment between the shaft and the housing without causing undue stress on the bearing or reducing its operational efficiency. They consist of an inner and outer ring with double-row steel balls and a cage that separates and guides the balls. It can handle both radial and axial loads, making it suitable for a wide range of applications.

FEATURES AND BENEFITS


  • Suitable for high-speed applications due to optimized design and reduced friction.

  • Helps maintain stability and performance even under dynamic and fluctuating operating conditions.

  • Ability to accommodate misalignment between the shaft and housing, compensating for shaft deflection and misalignment errors.

Yes, miniature ball bearings are designed to handle high rotational speeds, making them ideal for devices and equipment that require rapid movement.
