Custom shaft grounding ring

Installation / shaft reference

Installation reference placeholder: use an installation or shaft-side reference image.

Overview

Custom shaft grounding rings are reviewed when catalog RD/RDW or ST/STW structures do not match the shaft, envelope, or contact position. Brush contact can be reviewed for shaft side or end contact, with shape and size confirmed from drawings and application constraints.

Key features

• Drawing-led review

  Dimensions, contact position, and installation constraints are checked before the custom route is confirmed.

• Side or end contact review

  The brush contact arrangement can be reviewed for shaft side or shaft end contact where appropriate.

• Non-catalog fit

  Custom work is used when standard solid or arc-shaped families do not meet the required envelope.

• Manufacturing alignment

  The proposed structure is reviewed for repeatable production before moving beyond sampling.

Specifications

Published specifications shown here are limited to currently confirmed information.

Input required

Drawings, shaft geometry, available space, and target contact position.

Customization scope

Shape, size, and contact arrangement are reviewed according to the application.

Contact path

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

Review process

Engineering review is required before sample or quotation confirmation.

Typical applications

• Special motor frames or shaft geometries
• Projects where standard RD/RDW or ST/STW structures do not fit
• Applications requiring a specific contact position
• Programs that need a drawing-controlled shaft grounding ring

Installation notes

• Provide current drawings or photos with key shaft and envelope dimensions.
• Identify the intended contact position on the shaft side or end.
• Call out other grounding or insulated bearing strategies to avoid conflicting paths.
• Confirm the custom structure before sample or quotation approval.

FAQ

When is a custom ring needed?

Use the custom route when RD/RDW or ST/STW cannot match the shaft geometry, available space, or contact position.

Can the brush contact the shaft side or end?

Side or end contact can be reviewed according to the motor structure and available envelope.

What should I send first?

Send drawings or photos, shaft diameter, available space, and the preferred contact position.

Can you match an existing envelope?

We do not assume equivalence from appearance. Any replacement or custom design must be reviewed against the target motor.
