UP-200 Dust Seal UG10-109

The UG10-109 dust seal is an OEM replacement component designed for the KUPA UP-200 / UG12 handpiece. This aluminum dust seal is installed in the front-end assembly of the handpiece to prevent dust, debris and metal shavings from entering the high-speed bearings and spindle region, thus ensuring smooth, reliable operation at professional speeds.

Features

• revents ingress of dust and debris into critical bearings and spindle assemblies, which helps reduce premature wear and maintain tool longevity.

• Helps maintain smooth, stable rotation by preserving the cleanliness of the internal drive components.

• Cost-effective maintenance item: replacing the seal when worn is far less expensive than repairing damaged bearings or spindles.

• OEM-matched: Using the correct KUPA part ensures correct dimensions and performance, avoiding fitment issues from generic seals.

• Dimensions: Inside Diameter (ID) ~ 6.00 mm; Outside Diameter (OD) ~ 7.70 mm; Thickness ~ 2.60 mm.

• Material: Aluminum (high-speed rated) — suitable for the demanding internal conditions of a high-RPM handpiece

Installation Tips

• Confirm your handpiece model and revision uses UG10-109 — some variants may use a different dust seal part number.

• Inspect the seal groove and surrounding area for wear, corrosion or damage — replacing the seal without addressing a damaged groove may not fully resolve performance issues.
  

1. Unplug the handpiece and make sure it’s fully stopped before disassembly.

2. Remove the front housing or nose cone as required to access the dust seal location.

3. Remove the old dust seal, clean the groove thoroughly and remove any debris, metal shavings or lubricant residue.

4. Install the new UG10-109 dust seal, ensuring correct orientation and full seating.

5. Re-assemble the handpiece and perform a no-load test (run without a bit) at lower speed to verify smooth operation and absence of abnormal sound or vibration before full use.
