This set ring (part # UG10-209) is an OEM replacement part for the KUPA UP-200 / UG12 series handpieces. According to the parts listing, it is made of stainless steel. The “set ring” is a critical component used to secure or align parts in the handpiece’s front or motor housing assembly, maintaining proper spacing and stability during high-speed rotation.

Features

  • Maintains Precision Alignment: Because high-speed handpieces rely on tight tolerances, the set ring helps keep internal assemblies correctly located, reducing wobble or vibration.

  • Durability: Made from stainless steel, it’s designed for repeated high-speed use and wear resistance.

  • OEM Fit: Using the correct part ensures compatibility with original internal geometry, avoiding issues from non-spec parts.

  • Preventative Maintenance: Replacing the set ring during servicing can help restore professional feel and reduce the risk of misalignment-related wear on more expensive components (bearings, spindle, collet).

  • Material: Stainless Steel.

  • Dimensions:

    • Diameter: approx. 23 mm

    • Length: approx. 30 mm 

  • Application: Used in the front/middle section of the UP-200 / UG12 handpiece to maintain alignment of assemblies, secure components and ensure concentric operation under high RPM.

Installation Tips

  • Confirm your handpiece uses this exact part number; some variants or older revisions may use a different set ring specification.

  • Inspect the housing or groove where the ring fits for wear or deformation; even with a correct ring, if the groove is damaged the fit may be compromised.

  1. Disconnect and power off the handpiece; ensure the motor is stopped.

  2. Disassemble the relevant section (front housing or middle assembly) to access the ring location.

  3. Carefully remove the existing ring, clean out any debris or metal shavings.

  4. Insert the new UG10-209 set ring, ensuring it seats fully and evenly.

  5. Reassemble the handpiece and perform a no-load test (without bit) to check for smooth rotation and minimal vibration before returning to full use.
