SMC Corporation MY1C20-140L Pneumatic Cylinder

The SMC MY1C20-140L is a compact, mechanically jointed rodless cylinder with cam follower guide, delivering precise, low-friction linear motion in a 20 mm bore and a 140 mm stroke. Part of SMC’s MY1C family, it uses cam follower guides for smooth travel and a rodless design that reduces the overall footprint and simplifies mounting in tight spaces. The MY1C series covers bores from Ø16 to Ø63 mm and strokes from 100 to 2000 mm, with various stroke-adjustment configurations; the -L suffix identifies a left-stroke adjustment variant that can include a left-stroke adjustment unit with an adjust bolt and, in some versions, a shock absorber for low-load operation. Porting and piping options vary by model, with many MY1C20 configurations offered in bottom-ported, centralized-bottom piping layouts. This model is widely cataloged and supported in CAD libraries, reflecting its status as a standard choice for constrained linear actuation in automation equipment.
