Radial piston motors
Coating with BALINIT® C cuts static friction, prevents scuffing and improves the performance of the roller bearings.
The advantages in practice are considerable:
- over the whole length of the rollers, there is practically no evident wear
- the static friction between rollers and cast iron pistons is reduced by 40%
- the energy losses on starting the motor are reduced by 18%
- the stick-slip effect is eliminated
