[Clean & Pack] Retaining Ring C Type (External)

Brand :

MISUMI

Caution

[Specification Change] The material of stainless steel products will be changed sequentially starting in July 2025. Please see here for details.
There is a possibility that products and packages before and after the change may be mixed in the same shipment, but there will be no problems with use.
Cleaning also removes rust prevention oil, which may make the product more susceptible to rusting than an uncleaned product. Please be careful about the application location and storage environment.

Product Description

Three types of cleaning methods are available: degreasing, precision cleaning, and electrolytic polishing + precision cleaning. They can be ordered from one piece with the standard part number.
This eliminates the need for customer cleaning or outsourced cleaning, reducing the amount of time and effort required.
