BB Series Metric Ball Bearings

The BB series thin section bearings manufactured by AUBEARING have an inner diameter range from 30 millimeters to 900 millimeters, compatible with the bore and width of standard cross roller bearings. Compared to cross roller bearings, BB series thin section bearings excel in corrosion resistance, customized sealing, lubrication, and temperature tolerance. When factors such as cost, availability, corrosion resistance, tighter tolerances, torque, sealing/protection options, and high temperature resistance are crucial considerations, the BB series thin section bearings are the optimal choice.MOQ=1.

Customization options

  • Materials: AISI 52100 steel, AISI 440C stainless steel balls, ceramics (silicon nitride, zirconia, alumina, silicon carbide).
  • Seals/protective covers: Standard industrial seals typically made of nitrile rubber. AUBEARING also provides custom seals made from silicone, Viton®, FKM (fluoroelastomer) suitable for extreme temperature applications.
  • Temperature capability: Standard cross roller bearings typically operate up to approximately 212°F. AUBEARING's heat treatment processes ensure bearings can operate at higher temperatures.
  • Lubrication: AUBEARING offers a full range of lubricants to optimize bearing performance in demanding applications such as wet, high or low temperature, vacuum, and low torque conditions.
  • Cage materials: Options include brass, chrome steel, PEEK, PTFE, among others.
  • Plating: For applications requiring superior corrosion resistance, AUBEARING provides proprietary coatings for BB series metric ball bearings. This thin, dense chrome plating enhances the corrosion resistance of AISI 52100 to match or exceed AISI 440C stainless steel.
  • Clearance: Options include C2/CN/C3/C4/C5.

Operating limits:

  • Bearings are heat stabilized and can operate within a temperature range of -55 to +120°C (–65 to +250°F).
  • Brass cages can operate at temperatures equivalent to those of bearing rings and balls.
  • Allowable operating temperature range is –40 to +100°C (–40 to +210°F). Short-term exposure up to 120°C (250°F) is permissible.
