✦ Roller orientation – Rollers are positioned with their axes alternating at 90° in a single raceway, with each roller maintaining line contact with both raceways.

✦ Ring surface – Both rings are finished with plain, gear-free cylindrical faces, allowing external drive coupling.

✦ Ring production – Rings are produced via ring rolling process from vacuum-degassed steel, ensuring fine grain structure.

✦ Raceway tolerance – Raceways are ground to P4 tolerance class with a surface finish of 0.25 µm Ra.

✦ Hardness profile – Rolling surfaces hardened to 60–64 HRC with a case depth of 2.5–3.5 mm.

✦ Seal groove design – Grooves are machined with a rectangular profile and undercut relief for secure seal retention.

✦ Minimizes stress concentration – The 45° contact angle distributes forces evenly across the roller-race interface.

✦ Provides higher precision – The P4 tolerance class delivers superior rotational accuracy for precision applications.

✦ Withstands heavy shock loads – The deeper hardened case provides impact resistance for heavy-duty cycles.

✦ Prevents seal slip-out – The rectangular groove with undercut locks seals mechanically, preventing displacement.

✦ Allows flexible mounting – Threaded and clearance hole options accommodate various attachment methods.
