Two series of hydraulic cylinders for NFPA mounting are available from Ortman Fluid Power, Quincy, Ill., for medium- and heavy-duty operation.
The 3TH series is a heavy-duty design of tie-rod construction, rated for pressures up to 5,000 psi. They are available in with steel-bodied bores from 1.50 to 20.00 in. bores. Its robust design incorporates Ortman Fluid Power’s Uni-Cartridge rod gland, a retainer held rod gland for quick and easy replacement without dis-assembly of the cylinder body.
In addition, the medium-duty 7L hydraulic cylinder is slightly smaller for hydraulic applications requiring less pressure to operate. It uses the same design benefits, including the Uni-Cartridge rod gland, of the 3TH series but with the reduction of cost and weight.
The 7L hydraulic features a steel body and is rated for pressures to 2,300 psi, and is available in bore sizes from 1.50 to 14.00 in.
