AMBUSH®
AME
AMBUSH® Hydraulic Squeeze Bushings are used to clamp moving shafts to fixed housings in a wide range of applications.
Type ASA Squeeze Bushings are designed to resist axial forces only. They are commonly used in fixturing and reciprocating shaft applications.
Type AST Squeeze Bushings are designed to resist torque as well as axial forces. One or two holes (for dowel or roll pins) have been provided in the mounting cap to resist the torque and to insure that the Squeeze Bushing does not move.
Each AMBUSH is made of high quality alloy bronze or spring steel with a special plastic molded over the slotted squeeze surface. Seals are provided at each end to resist hydraulic pressure up to 5,000 psi (340 bar) depending on diameter. For higher pressure (up to 10,000 psi) contact our engineering department.
The ASB Bearing is made of 660 bronze.
Hydraulic pressure acts upon the molded sleeve (between the seals). The hydraulic pressure compresses the bushing radially over the entire length between the seals. This squeeze action locks the shaft to the bushing with high efficiency without introducing any movement to the shaft. Very accurate clamping can be accomplished in many fixture, machine tool and general applications.
