Clamp Cylinders

SMC's power clamp cylinder, series CKZT, was designed with a rounded cover design and release button with minimal protrusion to reduce weld spatter accumulation. The arm opening angle can be easily changed by replacing the stopper bolt.  Series CKZT is available with G or NPT threads and bore sizes equivalent to 40, 50, 63 and 80mm.

• Two types available: Base type (-X2800) and Tandem type (-X2900).
• Maximum Holding force 300 N.
• Clamping force up to 200 N.
• Compact width 20 mm.
• Lightweight 250 g (base type).
• Auto switches can be mounted.

SMC's MK-Z has an allowable moment of inertia 3 times higher than the conventional MK and MK2 styles.  The overall length is the same as the conventional styles, and mounting dimensions are interchangeable with the MK series.  Auto switches can be mounted on any of the 4 surfaces with no projection of the switch.

Combining compact cylinder size and rotational capability, the MK2 cylinder is designed for heavy duty clamping applications, with an available integrated arm that swings out of the way when the cylinder is extended. 90deg. clockwise or counter clockwise rotation is available, and clamping arms with adjustment screw are standard options. MK2 is available in 6 bore sizes from 20mm to 63mm and stokes from 10 mm to 50 mm.

This month sees the launch of our new range of lightweight, aluminium bodied power clamp cylinders, Series CKZ3T. Developed initially for the automotive industry, but suitable for welding applications and environments exposed to sparks from arc or spot welding, Series CKZ3T clamp cylinders, which can be used with a choice of 12 clamp arm options, are up to 39% lighter when compared to our existing Series CKZT range. Available in 50mm and 63mm bore size models and with a comprehensive range of standard opening angles (from as small as 15º) these double acting cylinders are constructed with a rubber bumper on the clamping side thereby decreasing the effects of impact when unclamping. Designed with a rounded top cover, to help reduce the potential build-up of weld spatter, Series CKZ3T can also be specified with either a metal or rubber cover (UL94 standard V0 compliant) as standard. Series CKZ3T cylinders are available with or without cassette type proximity switches (Turck or P&F options) and with single bolt cassette fastening, ensuring quick switch installation and removal.

The CK1-Z series is a clamp cylinder available in two styles of clevis widths (16.5mm, 19.5mm). It is a non-lube, compact, lightweight cylinder with a built-in speed controller. The CK1-Z is available in 3 bore sizes with stroke lengths up to 150mm. Options include easy speed adjustments, rod attachments and auto-switch capabilities.

With the addition of two new space-saving options to our popular Series C(L)KG and C(L)KP clamp cylinder we now have some great solutions for robot assembly and welding applications. These latest cylinders, which can be selected with or without lock, are almost 20% shorter and 50% lighter than our existing products. Available in 25, 32 and 40mm small bore sizes, these ultra-compact, slim style cylinders can also be used in conjunction with our small, magnetic field resistant, dual colour auto-switch range - Series D-P3DW.

SMC's CKZ2N power clamp cylinder conforms to the new NAAMS standard. The rounded cover design and release button with minimal protrusion, reduce weld spatter accumulation. The arm opening angle can be easily changed by replacing the stopper bolt.  The CKZ2N is available in sizes equivalent to 50, 63 and 80mm bore with arm opening angles ranging from 15°to 135°.
