Correct Mounting for Flap & POLINOX Wheels

Shop PFERD flanges for mounting compatible unmounted flap wheels & POLINOX grinding wheels on drive spindles. Built around defined wheel sizes & mounting dimensions, these flange options help workshops, maintenance teams & metal fabrication businesses identify the correct component before ordering.

Industrial Shed currently offers PFERD flange options covering selected 150, 165, 200 & 250 mm wheels. Start with the PFERD wheel type, confirm the diameter, check the bore requirement & match the correct flange designation.

PFERD Flange Size Guide

Fast selection: PFERD wheel type → wheel diameter → bore requirement → flange designation → drive setup.

What Are PFERD Flanges Used For?

PFERD specifies these flanges for mounting compatible unmounted flap wheels & POLINOX grinding wheels on drive spindles.

They should be treated as defined components within an abrasive setup rather than generic mounting accessories. A flange that appears physically similar isn't automatically suitable for the same wheel, bore or drive.

PFERD's flange design allows the clamping flange to sit countersunk within the compatible tool. For the larger flange, PFERD specifies a special clamping system that permits the compatible tool to work face-down very close to edges & in corners.

Where grinding forms part of a broader metalworking workflow, Fabrication Tools & Workholding can help complete the surrounding workshop setup.

Check More Than Wheel Diameter

Wheel diameter provides a fast starting point, but it isn't the only compatibility consideration.

► Confirm the PFERD abrasive tool type
► Check the wheel diameter
► Verify the required bore
► Match the flange designation
► Confirm the intended drive setup

PFERD states that the flange can be adapted to an existing drive spindle by drilling. Any adaptation still needs to comply with the relevant product & drive requirements.

For the RF FR 200-250 Bo. 12-40, PFERD lists:

► Bench grinder
► Flexible shaft drive
► Straight grinder

Workshops using straight-grinding equipment can also explore Die Grinders for related equipment. Always verify the specific machine, wheel & mounting requirements rather than assuming compatibility.

Built for PFERD Flap & POLINOX Wheel Systems

PFERD unmounted flap wheels use coated abrasive flaps arranged radially around the tool axis. Across this tool family, PFERD identifies applications including deburring, levelling, fine grinding, surface work & work on weld seams.

POLINOX tools form part of PFERD's fine-grinding & polishing range, with individual products intended for defined surface-processing applications.

The flange itself doesn't determine the grinding result. The abrasive wheel, workpiece material, drive, operating conditions & mounting arrangement all contribute to the complete setup.

This distinction is particularly important when comparing these products with Grinding & Cut-Off Wheels, which are different abrasive formats with their own selection requirements.

A Specification-First Buying Process

Buying the right PFERD flange becomes much simpler when the wheel information is available.

Identify the wheel.
Find the exact PFERD wheel type or designation rather than relying on appearance.

Confirm the diameter.
Determine whether the application falls within the 150/165 mm or 200/250 mm size group.

Check the mounting requirement.
Compare the required bore with the flange dimensions.

Verify the drive.
Confirm that the wheel, flange & drive combination is appropriate for the intended setup.

Order against the specification.
Use the PFERD designation, wheel size & mounting dimensions as the final reference.

Workshop Setup & Grinding PPE

Grinding & finishing should be considered as a complete workshop task. Tool condition, workpiece material, mounting requirements, operating conditions & appropriate workplace controls all contribute to the setup.

Keep different flange sizes identifiable where multiple abrasive systems are used within the same workshop. Inspect components before operation & refer to the applicable manufacturer information whenever the wheel, flange or drive changes.

Depending on the task & workplace risk assessment, relevant equipment may include Respiratory Protection & Accessories & Face Shields & Visors.

Planned equipment checks can also reduce last-minute preparation. Spring Jobsite Prep Getting Your Gear Ready covers practical preparation for tools & workshop equipment before busy periods.
