SMC manufactures a wide array of automation technologies for machine builders. Compressed air, coolants, and other fluids must be filtered, monitored, distributed and temperature controlled. We offer a complete range of world-class actuators, valves, sensors, industrial filters, fittings, regulators, temperature control devices, and more.

The sampling of products below demonstrates how SMC continually innovates to meet the evolving needs of the machine tool industry. Featured products are categorized by compressed air line, coolant line, and hydraulic line application.

Compressed Air Line


RHC High Powered Cylinder

High speed or high load cylinder applications frequently require additional speed and flow control devices to control the stopping of the load. SMC's RHC series features a longer cushion design which is capable of stopping heavy or high speed loads while maintaining the simplicity of a standard air cushion cylinder. This enhanced cushion allows the kinetic distance, which results in the ability to absorb up to 23.8 ft-lb of energy and operate reliably at speeds up to 118 in/sec. Even with the improved performance of the RHC, cushion adjustment remains as simple as adjusting the cushion needle valve. 


CQ2 Standard Cylinder

The CQ2 compact cylinder is the world's best selling pneumatic cylinder and can be supported globally. The CQ2 is available in 15 bore sizes from 12mm to 200mm. It comes standard with male or female piston rod threads. 42 standard options make it one of the most versatile cylinder series on the market. For mounting flexibility, it is possible to mount auto switches on any of the 4 surfaces.


SY 5 Port Solenoid Valve

SMC has improved product performance and reliability with the redesigned SY series valve.  By using H-NBR seal material for the main valve and seals, Ozone resistance has been improved.   Side, top and bottom port/pipe directions are available to allow flexible installation.  The SY is available in body ported or base mounted styles, and can be used individually or manifold mounted.


IR Precision Regulator

Series IR Precision Regulators are designed to be compact and light weight. The maximum set pressure has been expanded from the conventional 0.7MPa to 0.8MPa. Relief flow has been increased by nearly 5 times (compared to SMC IR201, IR401). The optional bracket and pressure gauge can be mounted on either the front or back of the unit.


ISA3 Digital Gap Checker

The ISA series is a non-contact style air catch sensor for applications requiring confirmation of work present for machining operations. Due to the construction of the sensor, fluctuations in the supply pressure does not influence operations. The ISA series is IP66 rated and is dust proof and drip proof.


VG342 Safety Dump Valve

Special version of the VG series valve that conforms to ISO13849-1 safety standard, categories 1 to 4. These are dual residual pressure release safety valve with detection of main valve position.


VHS Pressure Relief Lockout Valve

The VHS series provides a convenient means of isolating supplied pressure in a pneumatic system and exhausting downstream pressure for maintenance purposes.  The units can be locked in the exhaust position and can be an integral part of an energy isolation system.  Air flow direction is easily identified by handle orientation and labelling.  They can be used alone or can be conveniently connected to an FRL assembly using modular spacers.


VMG Blow Gun

Series VMG has a large effective area of 0.05in² (30mm²), without nozzle. Pressure loss is 0.725psi (0.005MPa) or less when nozzle bore size 2.5mm is used.  Piping direction is optional from the top or bottom.  Available nozzles include: male thread; high efficiency; low noise w/male thread; and extension nozzles. 

Coolant Line


SGC Coolant Valve

Series SGC coolant valve, with both CE and RoHS accreditation, provides the perfect solution for high speed machining. Due to the SGC's unique scraper, squeeze seal, grease channel and dry bearing construction, the valve's service life will exceed 5 million cycles. The introduction of a built-in magnet allows auto switches to be fitted, enabling confirmation of whether the valve is open or closed.


FN Industrial Filters

A low maintenance filter, series FN1 eliminates the need for element replacement. SMC's unique element construction is composed of a series of grooved filter plates and wave washers placed one above the other. When compressed, the gaps between the filter plates and wave washers filter foreign matter. When decompressed, the element widens the gap between the filter plates and wave washers, allowing dust and foreign particles caught between the plates to be washed away. The gaps between the filter plates are equally maintained by the wave washers to allow stable back-flush operation.


ISE80 Digital Pressure Switch

The ISE80 series is a digital pressure switch designed to measure fluids such as tap water, hydraulic fluid, silicon oil, lubricant, fluorocarbon, argon, ammonia, carbon dioxide, air-containing drainage and nitrogen.  Some of the features include 2-color indication, select from back piping and bottom piping, the addition of 2MPa and -101kPa types, also low leakage type, water hammer protection, easy operation, and standardization of CE, UL/CSA and RoHS compliance. 


KN Air Blow Nozzles

With the release of the KN series nozzles and gauge heads 30~90% of air consumption required for the current nozzle operation can be saved with the appropriate selection of the new nozzle and sizing. Many variations of nozzle are available with tube materials including nylon, soft nylon, soft copper pipe and OST tubing. Sizes range from 4mm-20mm.

Hydraulic Line


CH Hydraulic Cylinders

CH series hydraulic cylinders are available in compact, round body, JIS or tie-rod types. Nominal pressure ranges from 3.5MPa to 16MPa. Bore sizes are available, depending on the series, from 20 to 160. Auto switches are available on most models.


ISE75H Digital Pressure Switch

The ISE70/75(H) series pressure switches incorporate a large digital display to monitor both coolant and hydraulic fluids. These high performance, yet lightweight, pressure controls are available in three styles: the ISE70 for use with air or inert and incombustible gases (monitoring a set rated pressure range between –0.1 to 1MPa), and the ISE75 and ISE75H models (for use with fluids requiring a set rated pressure of up to 10MPa and 15MPa respectively). Available with Rc, NPT or G1/4 port thread options, and with fixed or selectable MPa or PSI pressure indications, these switches conform to both CE and UL/CSA global accreditations and IP67 enclosure ratings.


FH Hydraulic Line Filter

FH hydraulic line filter: Easy element replacement - Large M24 drain exhaust port - quickly reverse direction of fluid flow


FHBA Vertical Return Filter

FH series suction filters are compact and lightweight. Designed with an aluminum casted housing. Element can be replaced by simply opening the cover to detach the element without touching the pipes. The filter can be fitted with a differential pressure indicator which senses when the element is becoming dirty, facilitating maintenance and helping to avoid pump damage such as cavitations. The FHG series suction guard was designed to prevent collected dust from falling into the tank. Since all dust is eliminated during trial operation, it is not necessary to replace flushing oil. Options include differential pressure indicator, differential pressure indication switch, air breezer, and cap.

Temperature Control


HRS Compact Chiller

HRS compact recirculating chillers are designed to meet the widest range of single-point applications in both industrial and technology settings. The package design is robust enough for the factory, yet ergonomic and compact for lab installations. Coolant can be either heated or cooled within the set temperature range. Choose from six cooling capacities, air or water cooled refrigerant, and global power supply options. 


KKA Quick Connect Couplers

S coupler series KK employs a unique connection method. A slim body design and large effective area are achieved with a construction that does not use steel balls or valve springs and therefore does not restrict the flow path. Together with a reduction of the body size, pressing parts and resin parts are used to achieve an overall weight reduction.


PF3W Digital Flow Switch

Series PF3W digital flow switch is perfect for applications requiring a constantly monitored flow of cooling or cleaning water. The PF3W series has been improved both in design and operating performance over the PF2W flow switch.  Depending on the selected model, the PF3W is up to 40% smaller in volume, offering improved piping space and flexibility.  Designed to work with fluids up to 90ºC, these switches incorporate a built-in temperature sensor so both flow and fluid temperature can be effectively monitored at the same time.  Further improvements include the addition of 2 screens, incorporating 3-color numerical displays which can also be rotated in both clockwise and counter-clockwise directions, thereby offering even better display visibility during operation.  Available as non-grease type and with analogue output if required, the PF3W meets IP 65 enclosure protection standards and is both RoHS and CE compliant.
