High Temperature Spherical Roller Bearings 250°C (T250)

GMW T250 heat-resistant spherical roller bearings  are suitable for medium speeds and temperatures up to 250 °C (482 °F) maximum . Depending on the application, these bearings allow stable operation without maintenance.

We also design and supply a full range of Sealed Spherical Roller Bearings. These bearings are available in both single and double row designs. Spherical roller bearings are pre-lubricated with a specially formulated grease and sealed with a grease seal. This protects the bearing and lubricant from potentially damaging contaminants, reducing the frequency of re-lubrication under most application conditions. This can significantly reduce maintenance costs and increase bearing life in contaminated environments.

All T250 bearings have the following basic features:

• Made from AISI 52100 / SUJ2 / GCr15 steel material
• C3 or C4 clearance design compensates for temperature induced distortion 
• Adaptable 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 protection against corrosion
• Premium heat resistant grease forms a highly effective lubricant that reduces friction, allowing parts to operate more smoothly and providing greater economic benefit to the bearing.
  
• Heat-resistant steel roller cage provides high stability but low friction
