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 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).
