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.

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

(i)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.

Specifications / Overview

■Structure and Function of Hardlock Baring Nut
[Clean & Pack]Hardlock Bearing Nuts: Related Image

[ ! ] 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
