Weight Table
(Unit: g)
| Tube Inner Diameter (mm) | 16 | |
|---|---|---|
| *Basic Weight | 320 | |
| Additional weight per 15 strokes | 6.5 | |
| Mounting Bracket Weight | Axial foot type | 27 |
| Rod-end flange type | 21 | |
| **Double Clevis Type (With Pin) | 10 | |
- *The mounting nut and rod-end nut are included in the basic weight.
- *The mounting nut is not included in the weight for the double clevis.
Calculation method: (Example) CLJ2L16-60
- Basic weight: 320 (ø16 mm)
- Additional weight: 6.5 g / 15 stroke
- Cylinder stroke: 60 stroke
320 + 6.5 / 15 × 60 + 27 = 373 g

Caution when Locking
- Holding force (maximum static load) means the maximum capability of holding a static load that is not accompanied by vibration or impact after being locked and in a state with no load. It does not refer to a load that can be held constantly. Carefully check the following points when using (selecting) this product.
- If it rod slips because the lock's holding force has been exceeded, the brake shoe could be damaged, resulting in reduced holding force and/or a shortened lifespan.
- The upper limit of the load used under conditions not associated with kinetic energy when locking (such as for drop prevention) must be 35% or less of the holding force.
- Do not use in a locked state to sustain a load that involves impact.
*See the SMC catalog for information other than that detailed above.
