SPIETH Hydraulic Guiding and Clamping Sleeves guide and automatically clamp machine components such as quills, guide bars, clamp and support posts on automatic mechanisms and machines. The standard series has been designed for reciprocating motions. Upon request, we also furnish special guiding and clamping sleeves for both reciprocating and rotary motions.
SPIETH Hydraulic Guiding and Clamping Sleeves are made of alloy steel, are hardened and precision ground. Standard concentricity is within .005". for extreme precision requirements, concentricity of .0002" is also available. The unique design of the sleeves incorporates the hydrodynamic principle of lubrication; thus, when reciprocating the guide bar, the lubricant is wedged between the guide surfaces, creating a lubricant film and avoiding metal-to-metal contact. Wear on the mating guide surfaces is minimized and special lining is normally not required. For applications with little or no lubrication, SPIETH Guiding and Clamping Sleeves may be lined with bronze or plastic.
