Rubber Bearing Bushing for Gypsum and Plaster Grinder 190 mm GEKO CG80267-33

Replacement rubber bearing bushing designed for 190 mm gypsum and plaster grinders. This spare part fits sanding and smoothing tools with a 190 mm sanding head, providing elastic support between the rotating sanding pad and the tool housing. The rubber compound and construction offer damping of vibration and even distribution of load to the bearing area, helping to maintain consistent contact with gypsum and plaster surfaces during sanding operations.

Advantages

The rubber bearing bushing reduces vibration transfer to the grinder and operator, which improves control and consistency when sanding gypsum and plaster. Its wear-resistant rubber maintains stable support for the bearing and sanding pad, extending the working life of the tool assembly. Designed for easy replacement, the bushing restores the original alignment and rotational balance of the sanding head.

Suitable for

• Hand-held and power grinders with 190 mm sanding heads
• Sanding and smoothing gypsum board and plaster surfaces
• Maintenance and repair of sanding tool bearing assemblies
• Replacing worn or damaged rubber bushings to restore tool performance

Key specifications

• Diameter compatibility: 190 mm sanding head
• Material: rubber elastomer for vibration damping
• Function: bearing support and vibration isolation
• Application surface: gypsum, plaster and similar soft building materials
• Fit type: replacement bushing for compatible grinder models

How to use

Turn off and disconnect the grinder from power before replacing the bushing. Remove the sanding pad and any retaining elements to access the existing bushing. Extract the worn bushing, clean the bearing seat and surrounding surfaces, then install the new rubber bushing ensuring proper seating and alignment. Reassemble the sanding pad and retaining hardware, then test the grinder at low speed to confirm smooth rotation and reduced vibration before returning to normal use.

Usage recommendations

Inspect the bushing periodically for cracks, flattening or hardening of the rubber. Replace the bushing if excessive vibration, wobble, or uneven sanding results appear. Use appropriate personal protective equipment and follow the grinder manufacturer’s instructions during replacement and testing to ensure safe operation.
