Spherical Bearings SBT

Product catalog summary
Spherical Bearing Specifications
  • Material Composition: The race is made of 410 stainless steel, the ball is made of 440C stainless steel, and the liner is composed of Teflon fabric.
  • Types and Dimensions: The document lists various types of spherical self-lubricating bearings with dimensions provided in millimeters. Key dimensions include bore diameter (φB), outer diameter (φD), width (W), and height (H).
  • Performance Metrics: Each bearing type is associated with specific performance metrics such as no-load rotational breakaway torque, static limit load, dynamic load, and approximate weight.
Key Performance Data:
  • No Load Rotational Breakaway Torque: Varies across models, with a low torque maximum of 0.02 N・m for all sizes.
  • Static and Dynamic Load Capacities: Provided in kilonewtons (kN) for each bearing type, indicating the load-bearing capabilities.
  • Weight: Approximate weight is given in grams for each bearing type.
Additional Notes:
  • The Teflon liner is permanently bonded to the race's inner diameter.
  • Bearings are made to order, and availability should be confirmed with MINEBEA.
  • H7 tolerance levels are specified for different bore sizes, indicating precision in manufacturing.
