HT3

SWC High-temp Deep Groove Ball Bearings with the suffix HT3 are filled with a solid compound.
While running, small particles of the compound come lose and lubricate the bearing continuously.

Bearings filled with HT3 are suitable for low speeds and temperatures of up to 300°C, Depending on the application, these bearings allow maintenance-free operation for up to 6 years.

All HT3 bearings are only available with shields on both sides (2ZR).

All High-temp Deep Groove Ball Bearings offer the following advantages:

• Increased radial clearance (multiple of C5)
  as compensation for temperature-induced deformations of the production goods (rails, transport units)
   
• Heat stabilization
  for temperatures of up to 250°C
   
• Manganese phosphate coating (according to EN ISO 9717)
  ensures increased protection against corrosion, good adhesion of lubricants and smoother running
   
• Riveted sheet steel cage
  provides high stability yet low friction
   
• Extensive range
  6000 ... 6020
  6200 ... 6220
  6300 ... 6320

Available on request:

• Special lubrications
• Different sizes
• Different types of cages
