Materials: The body of the bearings is made from Chromium-Molybdenum Steel, zinc plated, or SUS630 Stainless Steel, passivated. The race is made from 410 Stainless Steel, heat-treated, and the ball is made from 440C Stainless Steel, also heat-treated. The liner is composed of Teflon/fabric.

Description of Types: The document provides detailed specifications for various part numbers (HRT3E to HRT30E), including dimensions, load capacities, and weights. Dimensions are given in millimeters, and load capacities are specified in kilonewtons (kN).

Key Specifications: Each part number includes measurements such as bore diameter (φB), outer diameter (φD), width (W), height (H), and thread size (TH). The static limit load, radial static ultimate load, and fatigue load are also specified.

Performance Notes: The Teflon liner is permanently bonded to the race's inner diameter. Axial load is defined as the smaller value between static load or proof load. Special specifications can handle higher fatigue loads. Bearings are made to order, and low torque is specified for all sizes with a maximum of 0.02 N・m.

Additional Information: The document includes a note on bore size tolerances, with specific μm tolerances for different bore size ranges.
