Washers - SW Type

Compression spring washers are tools for preventing loosening or disconnection of compression springs. The elastic energy per unit volume of compression springs is larger than for regular springs, resulting in higher energy absorption efficiency. Therefore, dedicated washers for compression springs are often used as a set with compression springs. Most compression spring washers are ring-shaped. Types include tapped types that make it easy to fix the spring and adjust the deflection, and brimmed types suitable for stabilizing the inner diameter of the spring. Also, 2-side cut types that have a linear cut on both sides of the ring, and products with treatment such as fine, uneven knurling are available. Select the shape according to the application. Materials such as resin or metal are often used due to their strength and resistance to deterioration.

[Clean & Pack]Round Wire Coil Springs - I.D. Referenced

MISUMI

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.

■Part Number for Clean & Pack Products

·Degreasing (Anti-rust single packing)	: Part Number SL-□□
·Precision cleaning (Degassing double packing)	: Part Number SH-□□
·Electrolytic polishing + precision cleaning (Degassing double packing)	: Part Number SHD-□□

Product Part Number	Cleaning Method	Packaging Type	Effects Compared to Uncleaned Product	Environment (Standard)	Process
SL-□□	Degreasing	Anti-rust packing	Oil removal	General environment	Regular assembly process
					Post battery assembly process
SH-□□	Precision cleaning	Degassing double packing	Oil removal Dust removal	Clean environment (Class 10 to 1,000)	Battery assembly process
					LCD-related post assembly process
					In-vehicle camera assembly process
SHD-□□	Electrolytic polishing + precision cleaning	Degassing double packing	Oil removal Dust removal Outgas reduction	Vacuum environment Clean environment (Class 10 to 1,000)	Pre-semiconductor process
					Liquid crystal deposition process
					Pre-OLED process

■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.

The series is standardized to maintain the spring constant uniformly to the same diameter.
