· Ubet Keyless Locking Devices are used in rotating machinery, producing clamping pressure between surface of locking device and shaft to create adjustable and releasable mechanical connection, so as to clamp gears, pulleys and other components to a shaft without threads or keys.
Materials of Ubet Locking Device are available in :
Carbon Steel S45C, C45E, 1045, 40Cr, 42CrMo4V
Stainless Steel AISI431, AISI304
· Ubet Machinery Timing Belt Pulleys and Toothed Bars/ Timing Bars.
Standard and non-standard pulleys according to drawings are available.
Materials of Ubet Timing Belt Pulleys are available in:
AlCuMgPb 6061 6082 Aluminum Timing Pulley
C45E 1045 S45C Carbon Steel Timing Pulley
