✦ Single-row crossed roller configuration – Cylindrical rollers are arranged alternately at 90° in a single raceway, maintaining 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.

✦ Monobloc ring construction – Both rings are manufactured as single-piece forgings, ensuring seamless material integrity without welded or bolted joints.

✦ High-precision 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.

✦ Maximizes design flexibility – The internal gear allows the drive pinion to be positioned at any point around the inner ring circumference, enabling flexible layout arrangements.

✦ Minimizes machine envelope – By integrating the gear within the bearing, the overall machine width is reduced, making it suitable for space-critical applications.

✦ Enhances gear protection – The internal gear design shields teeth from external debris, reducing the risk of tooth damage in abrasive environments.

✦ Eliminates external guards – The enclosed gear arrangement removes the need for additional protective covers, reducing overall machine weight.

✦ Provides smooth rotation – The precision-ground raceways and optimized roller geometry ensure stable, low-friction rotation for smooth operation.

✦ Simplifies sealing – The compact design allows effective sealing with standard NBR or FKM seals, protecting against contamination.
