Torsion Springs（Inner Dia. ID：Ø2）

Torsion springs are a type of wire spring. They are springs that receive a twisting moment around the coil. The shape of torsion spring ends is determined by the mounting location and method, enabling selection of 90-, 135- or 180-degree arm angles. Unlike compression springs and tension springs, torsion springs can reduce the design space and labor. Torsion springs can be classified primarily into close-wound and pitch-wound types. When selecting a torsion spring, it's important to carefully check the free length, average coil diameter and spring constant to select the right model for the usage environment or application. But when selecting models, note that different manufacturers define free length differently.

[Clean & Pack]Torsion Springs

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.

[Features]Arm angles of 90°/135°/180° are available for right and left winding.
