Cylinder With Lock, Double Acting, Single Rod CNG Series (CDNGBN20-75-D-B54L)
A cylinder with lock. Suitable for intermediate stops, emergency stops and drop prevention.
[Features]
· Uses the wedge effect to magnify the force applied to the taper ring and steel balls.
· Uses a brake shoe with superior wear resistance.
· The brake shoe length has been significantly increased (double that of the conventional model), providing outstanding durability and stable holding force.
· Structured so as not to be impacted by the quality of the lock-release air.
· The holding force is the same regardless of which direction the cylinder is locked.
· Manual override for unlocking.
· Format: non-lube type.
· Locking action: spring lock.

*The holding force (maximum static load) indicates the maximum capacity, not the normal holding capacity. Therefore, be sure to select the cylinder upon checking the details on p. 864 in the SMC catalog.
Standard Stroke
For types with auto switch, also refer to the table of minimum strokes for auto switch mounting on p. 880 in the SMC catalog.
| Tube Internal Diameter (mm) | *1: Standard Stroke (mm) | Long Stroke (mm) | Maximum Manufacturable Stroke (mm) |
|---|---|---|---|
| 20 | 25, 50, 75, 100, 125, 150, 200 | 201 to 350 | 1,500 |

| 40 | 301 to 800 |
*1: Intermediate strokes not listed above are produced to order. Spacer is not used for intermediate strokes.
*2: Long stroke applies to the axial foot type and rod-end flange types.
In the case of other mounting brackets or when the long stroke limits are exceeded, the maximum usable stroke is determined using the stroke selection table.
Structure Principle Drawing
Locked state construction principle drawing
Unlocked state construction principle drawing
Spring lock (exhaust locking)
The spring force that acts on the taper ring is magnified by a wedge effect, and is conveyed to the numerous steel balls that are arranged in 2 rows. These act on the brake shoe holder and brake shoe, which locks the piston rod by tightening it using a large force.
Unlocking is accomplished when air pressure is supplied to the unlocking port. The release piston and taper ring oppose the spring force, moving to the right side, and the ball retainer strikes cover section. The braking force is released as the steel balls are moved away from the taper ring by the ball retainer.
Stopping Accuracy
(Units: mm)
| Locking Method | Operating Piston Speed (mm/s) | |||
|---|---|---|---|---|
| 100 | 300 | 500 | 1,000 | |
| Spring Lock | ±0.3 | ±0.6 | ±1.0 | ±2.0 |
Conditions: Horizontal, Supplied pressure P = 0.5 MPa
Load weight: Upper allowable limit
Lock solenoid valve: Mounted directly to the unlocking port
Maximum value of stopping position variation from 100 measurements
