Tsubaki: The solution for shaft locking devicesU.S. Tsubaki POWER-LOCK ENTER THE “KEYLESS” SOCIETYOur POWER-LOCK solves your problems.Eliminate backlash damage to keyways from heavy loads the U.S. Tsubaki POWER-LOCK fits tightlyaround the shaft/hub and is not affected by load reversals.End your high machining expenses for long shaft keyways, splined shafts, threads, grooves and steps the U.S. Tsubaki POWER-LOCK offers exacting, slip-free location.Erase the headaches of shrink and press fits. The U.S. Tsubaki POWER-LOCK simplifies installationand removal.This easy-to-install unit slides into position and offers a keyless shaft-hub lock that will simultaneouslyhandle both high torque and thrust while increasing your shaft strength.The POWER-LOCK is easy to assemble you only need one tool. It is ideal for locking in largeor small sprockets, gears, pulleys, timing cams and rollers. Best of all, the POWER-LOCK is instock for immediate shipment.Features & ApplicationsnH igh Durability Against Reversing or Impacting LoadsThe POWER-LOCK connection is not affected by tortional load reversal orimpact, which damages the key and keyway connection. U.S. TsubakiPOWER-LOCK fits tightly around the shaft/hub and is free of backlash.nE asy and Precise PositioningThe POWER-LOCK offers 360-degree angular adjustment and isexcellent for indexing tables, cam mechanisms, gear drives anddouble-strand conveyor sprockets.nT hrust CapabilityThe U.S. Tsubaki POWER-LOCK can hold axial forces, too. Typicalapplications with these forces include indexing tables and bevel gears.nE asy Assembly and DisassemblyThe POWER-LOCK can be assembled and disassembledfrequently, so maintenance or replacement of worn parts is simpleand easy as compared to other methods (key and keyway, spline,shrink or press fits and welding).n I ncreased Shaft StrengthBy using the POWER-LOCK, no metal needs to be removed fromthe shaft (such as the cutting of a keyway). The strength of theshaft can be kept at its original diameter. This savings can beespecially noted on hollow-shaft applications.nE liminates Costly MachiningThere is no need for time-consuming machining of keyways. ThePOWER-LOCK offers substantial savings on long, heavy shafts. U.S. Tsubaki POWER-LOCK Offers a Whole New Approach toReplacing KeywaysMore information at www.ustsubaki.com

A-Level Biology - When designing a curriculum, we have strived to achieve a balanced course with challenge embedded from the start. We want to allow our students to explore the world of Biology and see the connections between all aspects of the planet that we inhabit. Biology provides foundations for understanding the natural world and is inextricably linked with the other science disciplines .
