Characteristics

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

✦ External gear on outer ring – Gear teeth are integrally machined on the outer circumference with a 20° pressure angle spur profile, featuring induction-hardened flanks to 50–55 HRC.

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

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

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

✦ Integrated seal grooves – Seal channels are machined into both rings to accommodate standard NBR, FKM, or silicone seals.


Features

✦ Enables high-speed indexing – The low-friction design supports rapid start-stop cycles, making it ideal for high-speed automation tasks.

✦ Reduces machine footprint – The compact single-row design allows smaller machine layouts compared to traditional bearing types.

✦ Simplifies alignment – The rigid crossed roller structure reduces the need for precise alignment during installation, saving time.

✦ Improves gear life – Induction-hardened gear teeth resist pitting and wear, extending the life of the drive system.

✦ Adapts to clean environments – The option for silicone seals makes it suitable for cleanroom applications like semiconductor manufacturing.
