Bimba's single acting air clamps provide gripping power on the out stroke and spring retraction. They are ideal for use in drill fixtures, bending, forming, crimping, and pressing operations. Because 3-way valves may be used, hook-ups are quick and easy.  Some air clamps are supplied with an adjustable front head so the stroke may be adjusted by as much as one inch.Pressure:  Air to 150 PSITemperature:  -40° to +125°Seal Material:  Custom molded one piece neoprene cupsBody:  Aluminum on adj. models, cast iron on H-12/H-283, cast aluminum on othersRod:  Nitrotec plated steel on 1 inch bore models, ground and polished on all othersFiltration:  40µ minimumEngineering SpecificationsPressure Rating: 150 PSI AirTemperature Range: -40° F (-40° C) to 250° F (120° C)Filtration: 40? minimumLubrication: Petroleum base oilMaterials:Rod: Nitrotec plated steel on 1" bore models, ground &polished on all othersBody & Cover: Aluminum on adjustable models, castaluminum on all other models (Cast iron on H-12 andH-283)Seals: Custom molded one-piece neoprene cups
