WELKER SMART STOP WELKER SMART STOP does all stopping & sensing functions in one part. SMART STOP minimizes engineering, field set up and operater adjustment time. WELKER SMART STOP eliminates: • Need for seperate mounts, brackets & flags. • Need for switch adjustments when shimming. • Improper adjustment of outboard switches. • Outboard switch vibrating loose in bracket. • Protecting outboard proxes from being stepped on or bent in tools.

AUTO LUBE OPTION Rail Slides Bearing assemblies in rail slides must be lubricated to maintain proper slide function and avoid rail damage. The auto lube option is a cost effective alternative to scheduled manual lubrication. Maintenance requires no tools or assembly - simply replace cartridge when empty. When ordered as an option for a new slide, it must be turned on by the customer after final installation. Recommended setting is 12 months. Rail slides require one unit for each bearing side. Replace every 12 months. Servo Slides Ball screws must be lubricated monthly. Insufficient...

R2 SLIDE ACCURACY POSITIONAL ACCURACY specifies the allowable deviation between the nominal position of a reference point on the carriage (D1 as shown) to the actual position that is achieved. TRAVEL ACCURACY specifies the allowable deviation along the plane of motion of a reference point on the carriage (D1 as shown) to the actual position during movement in other words, the allowable side-to-side movement (in the direction of Y) and up-and-down movement (in the direction of Z) as the unit travels. 1ST STROKE `0.80 (IF DUPLEX) TOTAL STROKE `0.20 TRAVEL ACCURACY (RUNOUT) Y-DIRECTION...
