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.
