Circlip Types We Source
External Circlips
DIN 471 / GB/T 894 external rings for shafts, in standard and heavy series.
Internal Circlips
DIN 472 / GB/T 893 internal rings for housings and bores.
E-type Rings
E-clips for light-duty shaft retention in small assemblies.
C-type Rings
C-type snap rings for quick-fit shaft and pin retention.
Bow Rings
Bowed external rings that accommodate axial play in bearing assemblies.
Custom Rings
Special section rings per drawing for transmissions, pumps and motors.
How to Choose the Right Circlip
Choose between external rings (fitted into a shaft groove) and internal rings (fitted into a housing groove), then match the groove diameter and ring thickness to your shaft or bore size. Standard series suits normal axial loads; heavy-duty series handles higher thrust. For stainless or corrosive environments, use A2/A4 rings. Provide the shaft or bore diameter plus the required standard, and our engineers will confirm the groove dimensions and correct ring specification.
Frequently Asked Questions
What standards are available for circlips?
We supply DIN 471/472, GB/T 894/893, ANSI/ASME B18.27 and ISO 464 rings in metric and imperial sizes.
How do I select external vs internal circlips?
External rings mount on shafts with an external groove; internal rings mount in bores with an internal groove. The ring type must match the application geometry.
Can you supply circlips for custom groove sizes?
Yes — custom diameters, thicknesses and materials are available per drawing, with samples in 1–3 days.
Are stainless steel circlips available?
Yes, A2 and A4 stainless retaining rings are available for marine, food and chemical applications.
