T-Bird Machining’s Unitized Pistons are now available in two types of bearing materials. First is our premium material recommended for water glycol systems as well as standard hydraulic applications. This is the choice material where environmental issues are a consideration. Second is an industry standard glass-filled material that is offered for standard hydraulic systems. Both types share the same advantages and features stated above. Unitized Pistons were previously limited to a minimum length of 1.000”. Newly developed technology has enabled us to produce piston lengths as short as ½”. Diameters are limited in this range so please contact sales for additional information.
