Adapter / Reduction Sleeve GEKO for Grinding/Cutting Discs 22.2 mm to 20 mm

GEKO reduction adapter converts the center hole of abrasive and cutting discs from 22.2 mm to 20 mm, allowing discs with smaller inner diameters to be mounted on standard 22.2 mm spindles. The adapter is designed to fit into the disc bore and provide a stable connection between the disc and the tool spindle, ensuring concentric rotation and correct seating of the disc during grinding or cutting operations.

Advantages

The adapter provides a reliable mechanical fit that reduces runout and vibration when using discs with non-matching bore sizes. Made for compatibility with common angle grinders and cutting tools, it simplifies inventory by enabling the use of multiple disc types on a single spindle size. Its compact design allows quick installation and removal while maintaining proper alignment and secure mounting during operation.

Suitable for

• Converting cutting and grinding discs with 20 mm inner diameter for use on 22.2 mm spindles
• Workshops and job sites where mixed-disc inventories require adaptable mounting
• Angle grinder tasks including metal cutting, grinding, and surface preparation when disc bore sizes differ

Key specifications

• Input bore adaptation: from 22.2 mm to 20 mm
• Intended for use with abrasive and cutting discs
• Fits standard spindle interfaces used on handheld grinders
• Compact, low-profile sleeve design for stable disc seating

How to use

Ensure the grinder is powered off and the spindle is stationary before fitting the adapter. Insert the adapter into the disc center hole so it sits flush, then place the disc with adapter onto the grinder spindle. Secure the disc with the usual clamping flange or nut and tighten according to the tool manufacturer's instructions. Verify that the disc runs true by manually rotating before powering the tool, and check that the adapter is properly seated and the assembly is balanced.

Usage recommendations

Use the adapter only with discs and tools rated for the operating speed of your grinder. Do not use damaged or cracked discs, and follow all safety guidelines for protective equipment and correct fastening torque. Periodically inspect the adapter for wear or deformation and replace it if any damage is found.
