Serious performance.
SPAC round body cylinders are the go-to choice where installation space is restricted and weight must be kept to a minimum. The circular aluminium alloy barrel provides excellent strength-to-weight ratio, while the chrome-plated piston rod delivers corrosion resistance and long service life in industrial environments.
Available in double-acting and single-acting spring return variants across bore sizes from 12mm to 100mm. Magnetic pistons are fitted as standard, and a comprehensive range of mounting accessories — foot mounts, flanges, trunnions, and swivel eyes — are available to suit any installation geometry.
