Specifications subject to change without notice or incurring obligation 5 Adjustable extend stroke Option -AS For strokes through 6" Full stroke adjustment is standard. Note! To maintain operator safety features of this option, it is NOT available with mounting styles: WR and WFR. Use caution when mounting to avoid creating pinch points. Not available with mounting styles PM and SM. Not available for 10" & 12" bores Nut Stop Adjustment Rod with fine pitch thread (See Dimension “BF”) Adjustment Nut with Mating Fine Pitch Thread 1/2 " Minimum Clearance when fully stroked Adjustment Nut Skirt Lock Screw Plastic Plug Stop Tube Rod Bushing Contact Surfaces totally enclosed Note: Use caution when mounting to avoid creating pinch points Dial-A-Stroke ® provides a rugged and precision adjustment of the extend stroke of the cylinder. The stop tube, adjustment nut with skirt, and minimum clearances combine to eliminate pinch points, thus providing operator safety. Note! Use caution when mounting to avoid creating pinch points with other parts of your machine design. The stop tube is black anodized aluminum, the adjustment nut is blackened steel with a black anodized aluminum skirt, and the nut stop is red anodized aluminum; all for corrosion resistance and appearance. The adjustment nut, steel for long life, includes a lock screw with a plastic plug so that the adjustment nut can be locked in place without damaging the threads. The nut stop is mounted on the end of the adjustment rod so that the nut cannot come off. The fine pitch threads on the adjustment rod and nut provide precision adjustment. (See dimension "BF"). Adjustment settings are simplified by convenient scale markings applied to nut skirt and stop tube. + (2 x Stroke) + Stroke Bore 1-1/8" 1-5/8" 2-1/2" 3" 4" 5" 6" 8" BA 1.13 1.25 1.50 1.50 2.00 2.25 2.25 2.50 BB 1.50 1.50 2.00 2.00 2.00 2.25 2.25 2.75 BC 1.67 1.67 1.90 1.90 1.67 1.67 1.67 2.54 BD 1.00 1.00 1.00 1.00 .75 .75 .75 1.13 BE .50 .50 .75 .75 .75 .75 .75 1.16 BF .050 .050 .063 .063 .063 .071 .071 .071 5-21-13 Rubber Bumpers Option Rod End only -BF Cap End only -BR Both Rod & Cap Ends -BFR Rubber Bumpers Multi-Power ® Cylinders BC + (2 x Stroke) BD + Stroke BE + Stroke BB Diameter BF Stroke adjustment per revolution BA Diameter A rubber doughnut is bonded to the cylinder head to act as the piston stop and absorb the impact of the piston.This reduces noise and absorbs energy, thus reducing damage to the cylinder and tooling due to pounding. The amount of rubber that extends beyond the normal piston stop is designed to compress and allow full stroke of the cylinder at 60 to 80 psi. If your application uses lower pressure or has high energy, consult engineering with application details so that rubber mass can be adjusted to meet your specific requirements. Because of the temperature limitations of the adhesives involved (-25° to +225°F), rubber bumpers are available in cylinders with standard internally lubricated Buna-N seals only. Use where noise reduction and impact absorption is desired. Note! On applications such as punching, shearing, setting blind rivets, etc., where high forces are built up and then released VERY quickly, the proper method of “catching” this type of load is to adjust the cylinder piston and the tooling so that at the point of breakthrough the piston is very close to the bumper. This reduces the dynamic load that the piston and bumper are required to absorb. 5.9
