RETAINING RINGS (CIRCLIPS) 

Oriental Industry Co., Ltd has been a leading manufacturer of retaining rings since 1986 in China. We dedicated ourselves in manufacturing quality retaining rings in most competitive cost. 95% of the products are exported to Germany, UK, Italy, Spain, Hungary, South Africa and Korea etc. With rapid growth of the business, we have invested the second phase production facilities, which is 4 times bigger in capacity than the current one. It was putting into production by the end of 2006. 

Product range

We manufacture a full line of inch, DIN, ANSI metric, UNI, GOST and JIS retaining rings/circlips.We have our own steel rolling plant for ensure the thickness of products. Except for the retaining rings listed below, we also provide custom-made retaining rings. All the tooling will be made on our own expense within 3 days.

(b) Stainless Steel

2Cr13, which is equivalent to 420, is frequently used for SS retaining rings. The hardness reaches HRC 44-50 after heat treatment. This makes our SS retaining rings much excel the just 'stamped stainless retaining rings'

(C) Copper and Brass

Brass, beryllium copper and other material are available according to the customer's requirement.The thickness of material is crucial for quality retaining rings. Some of the local raw materials can not reach the thickness required. We have our own facilities to roll them into tolerance before stamping.

Heat treatment and finish

- The standard heat treatment is quench-and-temper. Our modern equipment and skillful technicians guarantee each retaining ring within the mechanical properties required.

- Austempering is available on request.

- Carbon steel retaining rings are chemical blackened and dipped in anti-rust oil.

- A black corrosion-retardant phosphate coating on carbon steel is available on request.

- Zinc plating is available, but is not recommended.

- Stainless steel is polished into original color after heat treatment.

- No further finish on copper and brass.
