The Numatics Large Bore A Series is an NFPA Interchangeable cylinder line that is designed and built to excel in the most demanding applications. The Large Bore A Series encompasses many of the proven design features of the A Series.

Standard Specifications:

  • Meets NFPA specifications
  • Bore sizes from 8" through 14"
  • Piston rod diameters from 1-3/8" through 2-1/2"
  • Nominal pressure rating is 250 psi air
  • Standard temperature -10°F to 165° F(-23° C to 74° C)
  • NPTF ports
  • Flexible port and cushion location
  • Multitude of mounting options

Features:

  • Head and cap are machined from (6061-T6) solid aluminum bar and anodized for corrosion resistance. A recess at the piston mating surface allows the air to work on a larger effective piston area for faster breakaway.
  • The longer bronze rod bushing provides a maximum load bearing support. The material offers an excellent bearing surface with hard chrome plated piston rod. A graphite filled cast iron rod bushing is standard on 8" bore.
  • The carboxilated nitrile with Teflon compound is used in the rod seal. The lip seal design insures proper sealing and long life for no lube added service.
  • Rod wiper construction is a highly durable polyurethane.
  • The bushing retainer allows cartridge removal without disassembly.
  • Tie rods are 100,000 psi minimum yield steel for maximum holding power. Tie rod threads are rolled for strength and engagement.
  • Piston seals are carboxilated nitrile with Teflon compound for no lube added service.
  • The extra wide wear bard is provided to support maximum loading. The solid aluminum alloy piston is strong and lightweight. A nylon insert nut is used to attach the piston to the rod. (Nut is not standard on 8" bore).
  • The floating cushion design gives the fastest stroke reversal possible by providing instantaneous full flow to piston. Each cushion has a flush, retained adjustment needle.
