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)
P23 and P203 are special sliding materials offering high performance. They are designed for low-maintenance grease or liquid-lubricated applications.
Materials P23 and P203 have smooth sliding surfaces and can also be used in hydrodynamic conditions.
Materials P23 and P203 are available on request.
