Idler Pulley

The motionco Idler Pulley is designed principally as a back idler, for use on the reverse (smooth) side of a timing belt.

It may be used on a belt drive installation, singly or in pairs:-
1. to provide appropriate tension on the belt without the need to adjust the position of either the drive or the driven pulley.
2. to route the belt so that there is adequate wrap-round (tooth engagement) on a timing pulley.
3. to act as a tracking guide when used adjacent to an unflanged pulley.

The idler is suitable for use with our MXL Timing Belts and 3M Timing Belts (in both closed loop or Open-Length forms), or any belt with a smooth backing up to a maximum width of 9mm

Idler Pulley

It may also be used as a front idler where there is wrap round of at least 90 degrees, e.g. as the non-driver pulley on a linear motion drive. In this usage, it will be equivalent to a 3M Timing Pulley with 20 teeth, or an MXL Timing Pulley with 24 teeth

Features

  • Aluminium body with integral side flanges to constrain belt side movement.
  • Twin roller bearings, one at each end of the bore, to provide stable location and minimal rotational resistance.
  • Robust M5 mounting bolt, onto which inner bearing races are clamped, to simplify installation into a belt drive arrangement. An M5 nut and washer are also included.
  • Installation into a slotted aperture or onto a moveable arm will give tensioning adjustment facility.
