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 straightforward principle: the pistons are moved radially by hydraulics. Rollers transfer the radial force to a cam track, thereby transforming it into a rotary motion.
Roller bearing in radial piston machines with KS PERMAGLIDE® P203 half-shell plain bearings
The rollers are supported in half-shells made from the KS PERMAGLIDE® P203 material. The sliding shells have a smooth surface and support the rollers in the piston base. They are subject to extremely high pressure while only mixed friction is present. The working fluid is hydraulic oil.
Advantage: reliable function of the bearing with KS PERMAGLIDE® P203 plain bearings
  • Smooth sliding surface, ready to install
  • Low wear
  • Insensitive to edge loads
  • Good damping characteristics
  • Insensitive to impact loads
  • Good chemical resistance
  • Lead-free
  • Compliant with Directive 2011/65/EU (RoHS II)

 

P203 is a special, high-performance sliding material. It is designed for low-maintenance, grease-lubricated or liquid-lubricated applications. The material P203 has a smooth sliding surface and can also be used in hydrodynamic conditions. The material P203 is available on request.
