Industrial bearings for construction machines and hydraulics

Bearing in radial piston machines

PRODUCT USED

KS Permaglide® half-shell plain bearings, design PAX ... P23 / P203

Material: Permaglide® P23 / P203

FUNCTION

Radial piston machines are used in construction machines for crane rotation, for example. Radial piston engines generate very high torques at low speeds. It's a straightfor- ward principle: the pistons are moved radially by hydraulics. Rollers transfer the radial force to a cam track, thereby transforming it into a rotary motion.
