The Welker Floating Pin offers a unique opportunity to use an unlimited number of 4-way pins for part locating, significantly reducing part hole damage and pin wear. Parts are loaded when the pneumatic actuator is engaged and pin is centered and rigid. When the actuator is released the pin is allowed to radially float up to 3mm, and rotate up to 25 degrees. Lightweight and compact, the Floating Pin is available in two sizes and accommodates standard NAAMS pins, geo backups, and datum blocks. Custom pins and rests can be attached to unit's flat mount. Applications include bind-free part removal from geo end effectors and fixtures. Ideal for use in aluminum welding where there is considerable part movement. Floating Pins are ten times more repeatable over 3 million cycles than any retracting pin.
