✦ Single-row crossed roller configuration – Cylindrical rollers are alternately oriented at 90° within a single raceway, achieving line contact with both axial and radial raceways.

✦ Internal gear on inner ring – Gear teeth are integrally hobbed on the inner ring bore, featuring a 20° pressure angle spur profile with induction-hardened flanks.

✦ Integral mounting flange on outer ring – The outer ring incorporates a machined flange with through-holes, simplifying attachment without separate bolt-hole drilling.

✦ Precision-ground raceways – Raceways are ground to P5 tolerance class with a surface finish of 0.4 µm Ra.

✦ Dual-zone hardening – Raceways hardened to 58–62 HRC with a case depth of 2.0–3.0 mm, gear teeth hardened to 50–55 HRC.

✦ Accelerates machine assembly – The integral mounting flange on the outer ring allows direct bolting to adjacent structures, reducing part count and alignment time.

✦ Enhances torque transmission – The 20° pressure angle gear profile with induction-hardened flanks ensures reliable power transfer with minimal backlash.

✦ Reduces machine footprint – The internal gear design allows the drive system to sit within the bearing envelope, saving external space.

✦ Improves rotational accuracy – P5-tolerance ground raceways provide consistent roller motion, ensuring precise positioning in demanding applications.

✦ Extends service intervals – Deep case-hardened raceways resist wear, reducing the need for frequent maintenance.

✦ Simplifies seal replacement – Integrated seal grooves allow easy installation of standard NBR or FKM seals without modifying the bearing.
