Use this page as a catalogue reference only. 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 confirmed by drawing, load case, material, heat treatment, tolerance, and documentation requirements.
Diameter definition: D is the ring-body outside diameter and d is the ring-body inside diameter. For internal gear models, the gear is inside the bore, so the largest object that can pass through the center may be De, not d. Use Min bore = min(d, De).
