KE-SS series

Model number PL□□X□□KE-SS

To the model number selection screen

Stainless steel specification of the KE series for small diameter shafts.

  • - The main body is made of austenitic stainless steel, which provides high corrosion resistance.
  • - The tightening bolts have a special lubricating coating, so there is no need to apply oil during assembly.
  • ・Compared to other companies' products, it has a high transmission torque while being designed to suppress generated surface pressure, so it can be used on small hub diameter.
    Additionally, the number of tightening bolts is small, which reduces assembly work.
  • · As with the KE series, this standard product is compatible with positive tolerance shafts of servo motors, etc.
  • *Centering function included. No need for troublesome boss step processing.
  • *The boss does not move during assembly.

AS-SS Series

Model number PL□□X□□AS-SS

To the model number selection screen

This is the stainless steel specification of the global standard model AS series.

  • - Suitable for use in harsh environments with corrosive atmospheres.
  • The main body is made of austenitic stainless steel, and the fastening bolts (M12 and below) are made of stainless steel (SUH660) with a special lubricating coating on the surface. This prevents rust and provides a stable friction coefficient, maintaining high performance.
  • ・Due to the above, there is no need to apply oil during assembly.
  • This reduces assembly work.
  • *It does not have a centering function, so a guide must be provided on the boss.
  • *The boss does not move during assembly.

RE-SS Series

Model number PL□□X□□RE-SS

To the model number selection screen

This is a series designed specifically for stainless steel, with two installation methods to choose from.

  • - By attaching or detaching the included retaining ring, you can choose between two mounting methods: flange type and straight type.
  • - The main body is made of austenitic stainless steel, which provides high corrosion resistance.
  • - The tightening bolts have a special lubricating coating, so there is no need to apply oil during assembly.
  • - The product lineup includes small diameter shafts and has higher transmission torque than the KE-SS series.
  • *Centering function included. No need for troublesome boss step processing.
  • * In the case of flange type, the boss does not move during assembly, but in the case of straight type, the boss moves during assembly.
    It moves slightly forward in the axial direction. Please contact us for details.
