What is an skf high temperature bearing? Technical Specifications and Standards

An skf high temperature bearing is a specialized rolling element bearing engineered to operate reliably in environments where standard bearings fail. These bearings are designed to withstand continuous operating temperatures exceeding 150 degrees Celsius, with some variants capable of handling peaks up to 350 degrees Celsius. The key differentiator lies in the material science and internal geometry.

Core Technical Specifications:

  • Heat Stabilization: Rings and rolling elements undergo a special heat stabilization process to prevent dimensional changes at high temperatures.
  • Clearance Adjustments: Internal radial clearance (C4 or C5) is increased to accommodate thermal expansion of the shaft and housing.
  • Special Lubrication: High-temperature greases (e.g., synthetic oils with PTFE thickeners) or solid lubricants like graphite or molybdenum disulfide are used.
  • Material Selection: High-alloy bearing steel (e.g., 100Cr6 or 100CrMo7) is standard. For extreme temperatures, stainless steel or ceramic hybrid variants are available.

International Standards Compliance:

The skf high temperature bearing is manufactured to meet or exceed global standards including ISO 492 (dimensional tolerances), ISO 15241 (mounting dimensions), and DIN 625 (deep groove ball bearings). These bearings also adhere to the ABEC (Annular Bearing Engineering Committee) tolerance classes, typically ABEC 3 or ABEC 5 for precision applications. Compliance with these standards ensures interchangeability and predictable performance across different machinery OEMs.
