- R1 Series Idler Bushing Complete With Shaft
description
- V-belt and chain drives wear at an increased rate if allowed to run with insufficient tension. Adjustment of center distance is the best method of maintaining proper tension. In cases of fixed centers, drive tighteners and idlers provide the necessary means of take-up.
features
- Too much tension in a drive causes excessive belt chain and bearing wear
- Too little tension in a drive allows belt slippage or chain vibration, resulting in loss of power and additional wear
- All idlers should be used on the slack side of the drive
- V-belt drive idlers should be used on the inside of the belt
- allowances should be made for horsepower loss due to the reduced arc of contact
- Where necessary to use v-belt drive idlers on the outside of the belt, the reverse bending will reduce belt life
- Idlers used on the inside or outside of a drive should be located approximately 1/3 of the center distance from the large sheave, pulley or sprocket
- Sprocket idlers should be used on the outside of chain drives and with at least three teeth engaged in the chain
