 Torksleeve A 2

 A threaded bore in the  component bolted with the TSA2 generates a uniform locking pressure on the shaft by turning a nut. It offers repeatable, precise positioning along with high torque transfer capability.  

 Single sleeve, keyless locking device for greater toque transmission

 INCH - METRIC

Installation

 Screw the slitted sleeve with nut into your pulley or gear, and hand tighten.  Insert sleeve/pulley assembly onto a shaft.  Hold the sleeve with a wrench, and with a second wrench torque the nut against the component.  The component will slide axially on the shallow inclines of the sleeve threads, generating a high radial force locking the component and simultaneously contracts the slitted sleeve causing to grip the shaft

 Torksleeve A2 offers high toque and low cost for mounting keyless gears, pulleys on shaft

 Our newest, patented, high quality sleeve generates high radial and axial force.
