Spherical Roller Bearings T250 (250 °C)


GMW maker spherical roller bearings with suffix T250 are suitable for medium speeds and temperatures up to a maximum of 250 °C (482 °F). Depending on the application, these bearings enable stable operation without the need for maintenance.

Us offers a full line of Sealed Spherical Roller Bearings. These bearings are available in both single-row and double-row designs. Sealed spherical roller bearings are pre-lubricated with specially formulated grease and sealed with contact seals. This protects the bearing and lube from contaminants that could cause premature failure; in turn, reducing the frequency of relubrication required in most application conditions. This can dramatically reduce your maintenance costs and increase bearing life in contaminated environments.

All T250 bearings have basic characteristics such as:

  • Made from material AISI 52100 steel, Increased radial clearance (multiple of C3 or C4) design compensates for temperature-induced distortion can adapt to temperatures up to 250°C (effective operating temperature 230 °C (446 °F))
  • Manganese phosphate (Mn3(PO4)2) surface coating (according to EN ISO 9717) ensures enhanced corrosion protection
  • High-quality grease (suitable up to 250°C)
  • Heat-resistant steel roller retaining cage provides high stability but low friction
