External Tension Bushings are used as an easily replaceable wear component on shafts and spindles which are subject to high bearing loads and marginal lubrication. Their use provides designers a reliable, safe and economical operation of equipment in hostile environments.Their ID is smaller than the OD of the shaft onto which they are to be fitted, by a predetermined amount, to assure a tight fit.

Advantages:

• Because of their inherent elastic qualities, External Tension Bushings require lower press-on forces than conventional tubular steel bushings.
• Reduced cost of bearing point components.
• Long life.
• Ability to withstand high bearing point loads.
• Resistant to shock loads because of their high elasticity.
