111/112 series catalogue parameters

Default columns show ring-body D/d/H plus the critical envelope dimension used for installation clearance. Click a model number to open its generated detail page.

Diameter definition: D is the outer diameter of the ring body and d is the inner diameter of the ring body. For external gear models, the gear is on the outer ring, so the real maximum outside envelope can be De, not D. The structure must leave clearance for Max OD = max(D, De).

Catalogue notes

The 111/112 external gear crossed roller series is intended for applications where rigidity, controlled clearance, and rotational accuracy matter more than high continuous speed. The external gear makes it suitable for directly driven rotary axes, welding positioners, precision turntables, manipulators, indexing equipment, and compact industrial machines where the pinion remains serviceable from outside. Compared with a general single-row ball structure, the crossed roller layout should be reviewed more carefully for mounting flatness, preload or clearance target, runout demand, and shock-load conditions.

Catalogue dimensions are reference data and may extend beyond the current verified in-house machining range. Final manufacturing capability is confirmed against the customer drawing before quotation.

Final quotation and production are based on confirmed drawings, load conditions, material requirements, heat treatment, inspection documents, and packing requirements.
