Thrust Washers reduce friction and prevent galling.

Teflon-® washers match inside and outside dia. dimensions of shaft collars. Suited for rotary applications in harsh environments, washers are available in sizes from 1/2 in. ID x 1 1/8 in. OD up to 2 in. ID x 3 in. OD. Products are 1/16 in. thick, chemically inert, non-flammable, and operate over -450 to +500-°F temperature range. Applications include rotating components and pivoting robot arms.

Clamp-Type Collars evenly grip shafts.

One-, two-piece, and hinged smooth-bore Clamp-Type shaft collars can be tightened without gouging, dimpling, or crushing steel, glass, and acrylic shafts, or thin-wall tubing. Available in standard bore sizes from 1/8 in. to 6 in. ID, they can be made from stainless steel, steel, and aluminum, and electropolished, plated, and anodized, respectively.

Shaft-Hub Locks eliminate need for keyways.

PowerRing(TM) keyless locking devices mount mechanical components to round shafts. Non-marring bore contracts securely onto shaft while expanding OD tightly into ID of hub. Devices are adjustable, balanced to minimize vibration at high speeds, and prevent backlash damage caused by heavy loads. Available in 24 sizes ranging from Ã-¾ to 3 in. ID, they are suitable for mounting gears, sprockets,...
