Caution

See here for related information such as technical information on cleaning effects and other cleaned product lineups.
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.

■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

■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.

Unlike standard bearing nut sets, no keyway machining is required for gear washers and shafts.

Specifications / Overview

■Structure and Function of Hardlock Baring Nut

[ ! ] Wedge action does not change even when nuts are installed upside down of the figure on the left.

Fig.-1: When upper nut is tightened, stress is automatically applied in P₁ arrow direction. Horizontal stress continues to increase with tightening until upper nut closely contacts lower nut as shown in Fig.-2.
The nuts are fully locked by the wedge effect.

*Fig.-2: After nuts are tightened, internal stress remains distributed as composite stress of P₁ + P₂ + P₃ to resist external impact.

■Comparison with Conventional Products

Unlike standard bearing nut sets, no keyway machining is required for toothed washers and shafts.
