Description

The Foredom S-93/77 Shaft & Sheath Combo pairs the S-93 inner shaft (39") with the S-77 outer sheath (36-1/4") in a single, factory pre-lubricated assembly ready for immediate installation. Sometimes referred to as a key-tip motor shaft and sheath, this is the standard-length assembly supplied with many new Foredom systems and is a direct replacement for worn or broken shaft and sheath sets on compatible motors.

Features

  • Factory pre-lubricated assembly for quick, straightforward installation
  • Standard length: 39" inner shaft paired with 36-1/4" outer sheath
  • Compatible with Foredom SR, SRM, SRB, TX, TXM, TXB, LX, LXM, LXB, and PGX motors
  • Key-tip motor interface for secure engagement with compatible motors
  • Supports smooth, efficient power transmission for polishing, grinding, setting, and more

Installation & Use

  1. Unplug the motor before beginning any maintenance or installation.
  2. Remove the old shaft and sheath; inspect the sheath interior for wear or scoring.
  3. Attach the S-77 sheath to the motor, then insert the S-93 shaft fully until engaged.
  4. Reconnect the handpiece and run briefly at low speed to confirm smooth operation.

Notes

  • Never operate a Foredom motor without the outer sheath properly attached.
  • If a shaft breaks inside the sheath, the sheath interior may be damaged — replace the sheath along with the shaft to prevent premature wear.
  • Re-lubricate per Foredom's recommended maintenance interval or whenever operation feels dry or rough.
  • Longer shaft and sheath combos for extended reach are available separately.
