✦ Single-row crossed roller arrangement – Cylindrical rollers are alternately oriented at 90° in a single raceway, with each roller 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.

✦ Enables compact machine design – The internal gear allows the drive pinion to be placed within the bearing envelope, reducing the overall machine width.

✦ Protects gear teeth from external damage – The internal gear location shields the teeth from impact with adjacent structures or falling debris.

✦ Simplifies guarding requirements – The enclosed gear arrangement eliminates the need for external protective covers, reducing machine complexity.

✦ Reduces noise during operation – The internal gear meshing produces lower noise levels due to the damping effect of the surrounding ring structure.

✦ Facilitates hollow-shaft integration – The open center of the internal gear ring can accommodate shafts, cables, or other pass-through components.

✦ Improves operator safety – The enclosed gear design eliminates exposed pinch points, reducing the risk of injury during maintenance.
