The 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 PTFE 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 PTFE 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.
