Faqs

What does a floor grinder coupling do?

A drive coupling connects the motor and grinding-head assembly, transferring rotation through the machine’s drive system.

What is this coupling made from?

This replacement coupling combines aluminium components with rubber elements.

Is the coupling itself 250mm in diameter?

No. The coupling measures 106mm in diameter and 54mm overall thickness. The 250mm reference describes the floor grinder’s working diameter.

Does it fit every FP-250 or 250mm floor grinder?

No. Different machines and production versions can use different couplings. Confirm the dimensions, mounting arrangement and bolt-hole centre spacing before purchasing.

What mounting holes does it have?

The coupling has four 10mm bolt holes. Hole diameter alone does not confirm fitment; the centre spacing and mounting orientation must also match.

When should I inspect the coupling?

Inspect it during drive-system servicing or when investigating unusual vibration, noise or grinding-head movement. These symptoms can have several causes, so diagnose the fault before replacing parts.

What is included?

One replacement floor grinder coupling. Refer to the product photos for the supplied components.

Key features

Key Features

  • Aluminium and rubber coupling construction.
  • Replacement drive component for compatible 250mm floor grinders.
  • Connects the motor and grinding-head assembly.
  • 106mm coupling diameter and 54mm overall thickness.
  • Four mounting holes, each 10mm in diameter.
  • Supplied individually for repairs and maintenance.

Tool compatibility

Floor Grinder Compatibility

Suitable for selected FP-250 and other 250mm floor grinders with a matching coupling assembly. Compatibility depends on the machine version and drive configuration.

Before purchasing, compare:

  • Coupling outside diameter: 106mm.
  • Overall thickness: 54mm.
  • Bolt-hole quantity and diameter: four 10mm holes.
  • Bolt-hole centre spacing and orientation.
  • Motor-side and grinding-head mounting arrangements.
  • Available clearance within the machine.

A 250mm grinding diameter or an FP-250 model designation alone does not confirm fitment. Check the existing assembly and your machine’s parts information before ordering.

The Paddle aluminium and rubber drive coupling is a replacement component for compatible 250mm concrete floor grinders. Positioned between the motor and grinding-head assembly, it transfers rotation through the machine’s drive system. This floor grinder coupling measures 106mm in diameter and 54mm overall thickness. It has four 10mm bolt holes and combines aluminium components with rubber elements. The 250mm designation refers to the grinder’s working diameter rather than the coupling itself. Selecting the correct replacement requires more than matching the grinder size. Compare the coupling’s dimensions, bolt-hole centre spacing, mounting orientation and available clearance with the existing assembly. For FP-250 machines and other 250mm floor grinders, check the specific machine version because drive components may differ. Inspect the coupling and surrounding fasteners during maintenance or when investigating unusual vibration, noise or grinding-head movement. Damage elsewhere in the drive assembly can produce similar symptoms, so identifying the cause helps ensure the correct repair. Supplied individually by Paddle Wholesale Australia, this replacement drive coupling is suitable for equipment owners and repair technicians maintaining compatible floor grinders. Contact us with your machine details, measurements and photos if you need assistance comparing fitment. Keep your grinder operating at peak performance by pairing this coupling with our 250mm floor grinder spare parts collection.
