2" TO 1-1/4" METAL BUSHING ADAPTER FOR BENCH GRINDER WHEEL
The 2" to 1-1/4" Metal Bushing Adapter for Bench Grinder Wheel provides a straightforward way to adapt a compatible wheel with a 2" hub opening for use on a 1-1/4" arbor. Instead of replacing an otherwise suitable wheel because the center opening is too large, this reducing-bushing pair helps match the wheel to the required arbor size.
Designed for compatible bench-grinder and stationary wheel setups, the adapter uses a 2" outer diameter with a 1-1/4" inner diameter. The pair installs at the wheel hub to reduce the opening while providing centered support within the mounting assembly.
Because proper fit depends on more than arbor diameter alone, always confirm the wheel's hub dimensions, bushing seating, flange engagement, wheel width, and machine requirements before installation.

- Metal construction
- Useful for shops running multiple grinder and wheel configurations
- Installs at the wheel hub between the wheel and arbor assembly
Applications & Performance
This reducing-bushing pair is designed to adapt a compatible wheel with a 2" hub opening to a machine using a 1-1/4" arbor.
Common applications include:
- Bench-grinder wire wheel installation
- Stationary wire-wheel setups
- Adapting compatible 2" hub wheels to 1-1/4" arbors
- Replacement wheel installation
- Shop grinder configuration changes
- Maintenance and fabrication equipment setups
The bushings reduce the wheel opening but do not change the wheel's diameter, width, speed rating, or other machine-fit requirements.
Machine Compatibility
Use this pair to reduce a compatible 2" wheel hub to a 1-1/4" machine arbor. It can serve multiple bench-grinder and stationary wire-wheel setups; select it by the wheel hub and arbor dimensions, then check the complete mounted wheel.
Match all three parts of the setup: the wheel, the bushing pair, and the machine. The wheel must meet the grinder’s diameter, width and speed requirements, and both bushings must seat fully without preventing the flanges from clamping the wheel securely.
Safety Tips
- Inspect both bushings before installation and do not use damaged or distorted parts.
- Confirm the bushings fit securely and concentrically in the wheel hub.
- Never force an adapter into a wheel or onto an arbor.
- Verify the wheel is properly seated between the grinder flanges before tightening.
- Follow the wheel manufacturer's mounting instructions and the grinder manufacturer's requirements.
- Never exceed the maximum RPM rating of the installed wheel.
- Do not use an adapter to compensate for an otherwise incompatible wheel or machine configuration.
- Rotate the installed wheel by hand before startup to verify clearance and proper seating.
- Stand clear of the wheel's plane during initial startup.
- Wear appropriate eye and face protection when operating bench-grinding equipment.
