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 011/012 external gear series is normally selected when the drive pinion can be placed outside the rotating structure and kept accessible for adjustment, lubrication, and service. It is a practical first-screening option for medium-duty cranes, aerial work platforms, compact construction machinery, industrial turntables, agricultural attachments, and general OEM equipment where a single-row four-point contact structure provides an economical balance of combined load capacity, compact height, and manufacturable gear geometry. For RFQ review, confirm pinion position, tooth hardening demand, mounting-hole pattern, and whether the support structure can control ring deformation under overturning moment.

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.
