Cylinders with integrated guide Series QCTF – QCBF
Double-acting, magnetic, with double bearings and flanges
Ø 20, 25, 32, 40 mm
Ø 20, 25, 32, 40 mm
These cylinders have been designed to be used in applications where space is limited.
Regarding the bearings, the Slide Units are available in two versions, one with double sintered bronze bushes (Mod. QCTF) and the other with double linear ball bearings (Mod. QCBF).
The QCTF version would normally be selected when the side loads applied to the slide unit are high. Mod. QCBF is suitable for fast cycles (less side load) and higher precision.

The QCTF version would normally be selected when the side loads applied to the slide unit are high. Mod. QCBF is suitable for fast cycles (less side load) and higher precision.
The end cushioning is available in three different variants:
- Fixed mechanical cushion (standard);
- With two shock absorbers located on the body;
- With one shock absorber located central on the rear flange.
General Data
| Type of construction | Guided with double bearings and double flanges QCTF = sintered bronze bushes QCBF = linear ball bearings |
| Operation | Double-acting |
| Materials | Body = anodized AL flanges = zinc-plated steel piston rod = rolled stainless steel AISI QCTF columns = rolled stainless steel 420B QCBF columns = hardened steel C50 seals = PU |
| Mounting | Threaded and non threaded holes in the body |
| Strokes min. max | (see table) |
| Operating temperature | 0°C ÷ 80°C (with dry air -20°C) |
| Speed | 50 ÷ 500 mm/s |
| Stroke end cushioning Type A | Extended stroke – fixed mechanical cushioning retracted stroke – fixed mechanical cushioning we recommend preventing the piston from striking against the end covers |
| Stroke end cushioning Type B | Extended stroke – shock absorber retracted stroke – shock absorber |
| Stroke end cushioning Type C | Extended stroke – shock absorber retracted stroke – fixed mechanical cushioning we recommend preventing the piston from striking against the end covers |
| Operating pressure | 1 ÷ 10 bar |
| Fluid | Clean air, non lubricated. If lubricated air is used, it is recommended to use oil ISOVG32. Once applied the lubrication should never be interrupted. |
Coding Example
| QC | T | F | 2 | A | 020 | A | 050 |
| QC | SERIES | |
| T | TYPE OF BEARING T = sintered bronze bushes B = linear ball bearings | |
| F | VERSION F = double flange | |
| 2 | OPERATION 2 = double-acting | PNEUMATIC SYMBOL CD14 |
| A | MATERIALS A = anodized aluminium body – rolled stainless steel piston rod AISI 303 rolled stainless steel AISI 420B colums for QCTF – hardened steel C50 colums for QCBF | |
| 020 | BORE 020 = 20 mm – 025 = 25 mm – 032 = 32 mm – 040 = 40 mm – 050 = 50 mm | |
| A | CUSHION A = fixed mechanical cushion (standard) B = two shock absorbers located on the body C = one shock absorber located on the rear flange | |
| 050 | STROKE (see the table) |
