023/024 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 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).

Catalogue notes

The 023/024 internal gear double-row ball series is appropriate for heavier rotating equipment where the drive needs to stay inside the bearing envelope or protected from external impact and contamination. It can be considered for compact crane structures, machinery with restricted outside diameter, heavy-duty rotary tables, and OEM equipment that combines higher moment loading with a guarded drive train. Internal gear models should be reviewed for pinion installation space, tooth access, lubrication, sealing, and whether the equipment frame leaves enough clearance for assembly and future service.

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.
