Caution

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.

■Notes
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.

Type	Body Material		Cleaning Method
	Material	Hardness	Cleaning Method	Cleaning Environment	Packaging Type	Packing Environment
SL-STWS	SUS304−CSP	36 to 44HRC	Degreasing	General environment	Anti-rust packing	General environment
SH-STWS			Precision cleaning	Class 1,000	Degassing double packing	Class 10
SHD-STWS			Electrolytic polishing + precision cleaning

Products are packed by order quantity. Ex. If the order is for 20 pieces, they are packed in one package (incl. 20 pieces).
See the details of degreasing, precision cleaning, and electrolytic polishing shown at the bottom of the specification table.
