Link V-belts Super-T-Link profiles SPZ, SPA, SPB and SPC. Super-T-Link link V-belts are available with 20 m on the roll. Super-T-Link is preferred in industrial applications where the effects of temperatures (-40 C. to +100 C.), oil, water, chemicals or abrasive media greatly reduce the service life of conventional V-belts. The durability of Super-T-Link is many times better in these areas.
