Bearing arrangement for radial piston units

A hydrostatic radial piston unit of the cam-lobe type of construction comprising:

• a non-rotary, stationary shaft defining a rotational axis of the hydrostatic radial piston unit;
• a non-rotary, stationary casing housing the shaft in a torque proof connection;
• a cylinder block arranged stationary in torque-proof connection with the stationary shaft on a front end portion of the stationary shaft protruding from the stationary casing;
• a rotary casing which is rotary around the rotational axis and surrounds the cylinder block at the protruding front end of the stationary shaft;
• exact two roller bearings which are arranged as a pair of roller bearings next to or in a close proximity to each other,
• wherein
• the pair of roller bearings rotary supports the rotary casing against the stationary casing, and is disposed in the axial area adjacent to the cylinder block side facing toward the stationary casing, surrounds at least partially a hollow shaft part of a rotary distributor, and is arranged in an axial overlapping area in which the stationary casing and the rotary casing overlap.
