Fenner Taper-Lock® Dual Duty pulleys are India's first standard range of metric pulleys. They eliminate reboring and keywaying problems since each pulley need not be finished according to different bore and keyway requirements. With Taper-Lock® Bushes, changes in the diameter and position of pulleys are easily made. These metric pulleys are precision machined and have dual duty grooves to perfectly match V-Belts as well as Space-saver Wedge Belts.
Using Fenner Taper-Lock® Bushes,it is possible for unskilled labour to achieve 'shrink fit' of pulleys, couplings,etc. on to shafts only using a hexagon wrench.
The arrangement of half-threaded holes and longitudinally split tapered bushes ensure maximum grip and fast, easy fitting. Tightening of the screws into the threaded holes in the hub forces the bush into the taper bored components, thereby effectively contracting the bore of the Taper-Lock® Bush untilthe equivalent of a shrink fit is obtained.Taper-Lock® 'Bushes are suitable for metric shafts and can also be supplied with ImperialBores and Keyways.
