How It Works Types Of Cylinders Three-Position Cylinders This multi-position Original Line stainless body cylinder provides three positive stroke positions with a single cylinder. Cushion Cylinders These include adjustable air cushions that slow cylinder speed at the end of stroke, reducing impact and extending cylinder life. Cushions can be ordered on rear, front or both ends, and can be ordered in combination with magnetic pistons. These include a magnet on the piston, designed to operate Bimba switches to actuate programmable controllers, relays, solenoids, timers or other electrically operated...

How it Works Cushion Energy Absorption ORIGINAL LINE CYLINDERS Cylinders with air cushions provide a possible solution to destructive energies. The air cushion traps a small amount of exhaust air at the end of stroke, providing an air pocket that decelerates the load. This reduces the potentially destructive energy being transmitted to the cylinder and other components. The following is a brief explanation on how to determine the energy level of your application and decide if an air cushion can provide adequate energy absorption. For a more detailed description, consult the factory at 1-800-44-BIMBA....

How To Specify Specification Details Accessories have separate catalog numbers and are shown at the end of each bore size section. Most accessories are zinc-plated carbon steel. We also offer stainless steel accessories in some bore sizes. Lubrication Standard Original Line Cylinders are pre-lubricated at our factory with a semi-synthetic grease and do not require additional lubrication during their service life. In some instances where a specified option is not conducive to our standard grease prelubrication, such as our High Temperature and Hydraulic options, alternate standard pre-lubrications...

How To Specify Specification Details ORIGINAL LINE CYLINDERS Mounting Mounting should be by the threaded stud ends, pivot or bolt holes provided. Mount cylinders to provide alignment with the driven mechanism, avoiding side loads that restrict the free operation of the cylinder. Free Test Cylinder Since 1975, our policy has been to provide a FREE TEST CYLINDER to any qualified original equipment manufacturer. This service is provided at no obligation, but we would appreciate a copy of your test results. Contact us or your local stocking BIMBA distributor for more information. Special Cylinders...

How To Specify Specification Details Fractional stroke lengths for single and reverse acting cylinders, both standard and nonstandard, require special calculations to determine cylinder dimensions. The following equations apply: Single Acting Cylinders Calculate the length of next whole standard increment of stroke, then subtract the difference between desired stroke and next longer whole increment of stroke. Double Acting Cylinders Add desired stroke length to base length of cylinder. Example: 041.25-D 040-D Base length = 2.97” Example: 092.75 090 Base length = 1.94" Plus 1.56 per inch of stroke...
