Mar 12, 2003 Dowel Bushings align mating components and provide ID clearance hole for bolt, eliminating need for separate dowel hole. Spring Dowels align mating components when bolt must be located in separate location. Both products protect bolts from shear loading that will cause premature failure of bolt. Sizes are available for use with 5/8 in., 3/4 in., 14 mm, and 16 mm bolt sizes. They are made of heat-treated, high-carbon spring steel.

Feb 05, 2003 Series PSV 2001 is offered in sizes from 20-200 mm and 3/4-7 7/8 in. Unit provides backlash-free, 360° grip without use of keyways that cause frequent failures. Stainless steel and electroless nickel-plated assembly is corrosion resistant. Mechanism is self-releasing and non-self-centering. It is suited for reversing applications where keyways develop stress fractures, such as pulleys, bevel gears, sprockets, and sheaves.

Sep 18, 2002 Conduit Sealing Bushings stop water, dust, or gas under pressures up to 100 psi from entering electrical enclosures. Compact bushing is made of two PVC coated metal discs with one-piece neoprene sealing ring positioned between. Discs and ring are compressed together by stainless steel screws. Zinc plated, malleable iron locking collar is optional. Bushings are available for Schedule 40 rigid conduit, mechanical pipe, cast iron pipe, and copper tubing.

Aug 28, 2002 Headstock and sub-spindle collets are ground to precise size and TIR to meet precision machining requirements. Carbide-lined, Swiss guide bushings keep stock clean and unmarked, and extended-nose collets are suited for pick-off work or to compensate for tooling interference. Heat-treated to 40 Rockwell at head, they also serve as emergency collets.

Apr 17, 2002 STAR Torque-Resistant Linear Bushings are suitable for applications requiring shaft guideway to transmit both linear motion and torque while remaining torsionally stiff, such as one-armed swivel grippers or robots. Bushings can be installed without parallel second shaft normally required in standard applications to resist cocking loads. They are available in rotationally symmetrical sleeved or flanged designs, with solid or tubular shafts.
