The SMC 10-CUJB20-35D is a clean room specification mini free mount cylinder from the CUJ series with a 20mm bore and 35mm stroke. Part number decoded: CUJ = mini free mount cylinder, B = basic, 20 = bore mm, 35 = stroke mm, D = double-acting. The 20mm bore is the largest in the CUJ range, and the 35mm stroke extends beyond the standard 30mm maximum typically cataloged, indicating this is a special or extended-stroke variant ordered to meet specific application travel requirements.
At 20mm bore generating approximately 188N at 0.6 MPa, the 35mm stroke provides 5mm of additional travel beyond the standard CUJB20-30D maximum. This extra reach matters in applications where 30mm falls just short particularly in fixture positioning, multi-stage shuttle mechanisms, and tooling engagement operations where the cylinder must bridge a specific gap. The free mount body installs from any surface without brackets, and the 20mm bore bridges the gap between micro-cylinders and full-size CQ2 compact cylinders.
Note that the 10-CUJB20-35D does not include the M (magnetic piston) suffix, so auto-switch position sensing may not be available without the magnetic piston option. Verify switch compatibility if end-of-stroke detection is required. For the standard maximum stroke with magnetic piston, see CUJB20-30DM. For shorter strokes, CUJB20-20D and CUJB20-25D are available. If you need more than 188N, step up to the CDQ2B25 or CDQ2B32 compact cylinders. Clean series (10-) fluorine grease, Particle Grade 1.
