Hydraulic Cylinders

Surface Finishes exceeds the most demanding specifications for dimensional tolerances and surface finishes for hydraulic cylinders, 3/4″ to 48″ ID – up to 36′ long.

For small bore items, 3/4″ to 6″ inside diameter, we achieve tolerances of +/- 0.001″. For large bore items, 6″ to 48″ inside diameter we typically hold +/- 0.002″.

Given our custom designed and engineered equipment set, we are able to hone items that range in length from inches up to as long as 36 feet.

Our typical surface finishes are in the range of 8 -10 microinches Ra for most commonly used industrial materials and as low as 2 microinches Ra on some specialty materials.

We offer both through hole and blind hole precision honing services.  Our finishing and refurbishment services are used for parts that go into everything from heavy equipment to fluid control and jacking systems.
