Overview

RD/RDW is the solid shaft grounding ring family. It uses the same shaft-current diversion principle as arc-shaped and custom rings; the difference is mainly structure, mounting approach, and fit. The solid structure is generally friendlier for smaller shaft diameters, with interference-fit or screw-fastened mounting reviewed by application.

Key features

• Solid ring structure

  RD/RDW uses a solid ring form factor and is reviewed where the shaft and mounting envelope support this structure.

• Same grounding function

  Like arc-shaped and custom rings, the purpose is to divert shaft current away from motor bearings.

• Mounting reviewed by application

  Interference-fit or screw-fastened mounting can be reviewed according to shaft size, available space, and assembly conditions.

• Sizing support

  Shaft diameter, shoulder clearance, and contact position are checked before the final recommendation.

Product family

RD/RDW solid shaft grounding ring.

Mounting approach

Reviewed for interference-fit or screw-fastened installation based on the motor structure.

Contact path

Metallized carbon fiber contact provides a low-resistance shaft-current path when correctly fitted.

Fit review

Shaft diameter, available space, and contact position are confirmed before quotation.

Typical applications

• Motors where a solid ring structure fits the available shaft and mounting envelope
• Smaller shaft diameter applications after fit review
• VFD-driven industrial motor bearing protection
• Projects where RD/RDW structure is preferred by drawing or installation constraints

Installation notes

• Confirm shaft diameter, available axial space, and contact position before selecting the series.
• Choose interference-fit or screw-fastened mounting only after application review.
• Keep the shaft contact area clean and suitable for stable fiber contact.
• Do not assume interchangeability across motor frames without fit confirmation.

FAQ

What is RD/RDW?

RD/RDW is Volsun's solid shaft grounding ring family.

Is RD/RDW electrically different from ST/STW?

The grounding purpose is the same. The practical difference is structure, mounting approach, and fit for the motor envelope.

When should I consider a solid ring?

Consider RD/RDW when the shaft diameter, mounting space, and assembly conditions suit a solid ring structure.

What information do you need for a quote?

Shaft diameter, available mounting space, contact position, and motor photos or drawings are the key starting inputs.
