1 Pancake ® Cylinders Specifications subject to change without notice or incurring obligation 1.13 Option Information Original & "T" Series 8 Bores, 1/2" – 4" SUFFIX OPTIONS CLEVIS (Pivot) MOUNT Ports in Line with Slot -PM Ports 90° to Slot -SM SUFFIX OPTIONS MODEL NUMBER SUFFIX C-221-X-PM with RC-38 C-221-X-EPM C-221-X-F EYE (Pivot) MOUNT Ports in Line with Tang -EPM Ports 90° to Tang -ESM THREADED NOSE MOUNT -F THREADED NOSE with pilot diameter provides convenient, rigid and precision mounting. A hex mounting nut is included as standard and is also available separately. On bores 1-1/8" (121) and 1-5/8 (221) a urethane rod wiper is included, as standard, to exclude dirt from the rod bushing and seal. Available on all series, bores:1/2" (5), 3/4" (7), 1-1/8" (121), 1-5/8" (221), all strokes, all actions. See Option Specifications pages of desired bore and action for complete dimensional details of cylinder and mounting nuts. EYE MOUNT provides a pivot point attachment to allow pivotal motion of the cylinder as the piston rod extends or retracts. The pivot is bushed with an oil filled powdered metal bushing. On bore 1-5/8" (221) the Eye Mount can be rotated 90° to provide either -EPM or -ESM option. To fur- ther assist in the mounting, rod clevises and clevis brackets are available. In many applications requiring pivotal mounting, the cylinder is mounted with its centerline horizontal. Due to the weight of the cylinder and its at- tachments, this can result in some off center loading, and possibly binding of the piston and rod, causing accelerated wear. For such applications the “T” Series cylinders are recommended. Available on all series, bores:1/2" (5), 3/4" (7), 1-1/8" (121), 1-5/8" (221) and 2" (321), all strokes, actions: -X, -XK, -O, -OP. See Option Specifications pages of desired bore and action for complete dimensional details of cylinders, rod clevises and eye brackets. CLEVIS MOUNT provides a pivot point attachment to allow pivotal motion of the cylinder as the piston rod extends or retracts. The pivot is bushed with an oil filled powdered metal bushing. The pivot pin (416 stain- less steel) and clips are included as standard. On bores 1-5/8" (221), 2-1/2" (521), 3" (721) and 4" (1221), the Clevis Mount can be rotated 90° to provide either -PM or -SM option. To further assist in the mounting, rod clevises and eye brackets are available accessories. In many applications requiring pivotal mounting, the cylinder is mounted with its centerline horizontal.
