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 23 flanged series is suited to equipment where installation space, weight, and simplified mounting are more important than maximum bearing section size. The flange can reduce the need for thick adapter plates and helps designers locate the bearing in compact frames. Typical applications include small cranes, light-duty vehicle-mounted equipment, man lifts, packaging turntables, food-processing equipment, light automation, and compact industrial rotary units. For selection, confirm whether the flange faces can be fully supported and whether vibration or thrust loads require additional axial location features.

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.
