Pneumatic seal K55 63x12x10

Pneumatic piston seal K55, 63 × 12 × 10 mm, made by Kastas (product code K55-063), is for standard pneumatic cylinders. The profile is a complete double-acting piston: an aluminium body (disc) with a vulcanised layer of nitrile rubber (NBR), 70 Shore A. The special geometry of the sealing lips keeps an optimal lubricating film, low friction and smooth reciprocating motion inside the cylinder. Venting channels integrated in the metal part give stable, reliable operation under pressure also at the end of the stroke. No additional seals are needed between the piston and the rod: the static seal on the inner diameter is the vulcanised elastomer layer itself. The element is fitted directly on the rod, pushed onto the clamping collar and secured with a nut. Technical data and dimensions: Inner diameter (d): 12 mm Outer diameter (D): 63 mm Total height (B): 10 mm Width of the mounting face (b): 8 mm Diameter of the inner shoulder (d1): 26 mm Height of the metal disc (s): 4 mm Depth of the recess (h): 4,5 mm Material: nitrile rubber (NBR 70 Shore A) + aluminium (AL9901) Working pressure (maximum): ≤ 12 bar Speed (maximum): ≤ 1,0 m/s Medium: treated, filtered and lubricated compressed air More technical information and drawings of the K55-063 profile are in the manufacturer's documentation or the technical documentation of the elastoring.eu shop.
