6.35 mm Micro Bearing Inner / Outer Ring Remover

Bearing Outer Ring Remover for High-Speed Dental Handpieces
For Bearing Size: 3.175mm x 6.35mm x 1.9mm–2.78mm

Dental Turbine Bearing Puller

The Bearing Outer Ring Remover is a precision dental maintenance tool designed specifically to extract the outer race (ring) of miniature bearings that remain lodged in the head or cap of high-speed dental handpieces after the inner parts of the bearing are removed or worn out.

This is a common challenge during handpiece repair, especially with small bearings like the 3.175mm x 6.35mm used in many high-speed turbine systems. The tool enables quick, safe, and damage-free removal of the outer ring—without scratching or deforming the internal cavity of the handpiece head or cap.

Compatible Bearing Sizes:

• Inner Diameter: 3.175 mm

• Outer Diameter: 6.35 mm

• Width: 1.9 mm to 2.78 mm

Commonly found in:

• High-speed dental handpieces

• Turbine heads

• Handpiece end caps

⚙️ How It Works:

When the bearing’s inner components are removed or broken, the outer ring often remains press-fitted inside the head or cap. Since the ring is thin and fragile, using improper tools like tweezers or screwdrivers may damage the handpiece or fail to extract the ring.

The Bearing Outer Ring Remover addresses this by expanding behind the stuck ring and gently pulling it out.

Tool Structure:

• Micro-expansion jaws or pin arms designed to insert into the bearing ring

• Thumb screw or rotating handle to open and grip from behind the ring

• Extraction shaft or puller knob to pull the ring outward

• Made from hardened stainless steel for durability and precision

Step-by-Step Instructions to Use:

1. Inspect the Handpiece Head or Cap:

   • Confirm that the bearing’s outer ring is still inside and not loose.

   • Clean the area for clear visibility.

2. Insert the Tool:

   • Carefully insert the micro jaws or pins of the remover into the center of the bearing ring.

   • Ensure the tips go past the edge of the outer ring—this is crucial for proper grip.

3. Engage the Grip:

   • Turn the thumb screw or expansion knob to open the jaws behind the ring.

   • You should feel slight resistance as the jaws position themselves firmly behind the bearing’s outer edge.

4. Pull the Ring Out:

   • Once the ring is gripped, use the puller handle or slide hammer (if included) to gently but firmly extract the outer ring.

   • Do this slowly to avoid stressing the handpiece walls.

5. Inspect and Clean:

   • After successful removal, clean the bearing housing thoroughly.

   • Inspect for any wear or damage before inserting the new bearing.

Maintenance Tips:

• Always clean the tool after use with isopropyl alcohol or ultrasonic cleaner.

• Avoid dropping or bending the micro tips—they are precisely machined and fragile.

• Store the tool in a dry case to prevent corrosion.
