Bosch Rexroth

The Hägglunds Hydraulic motor from Bosch Rexroth is suitable for many heavy-duty applications. The CB is of the radial-piston type with a rotating cylinder block/hollow shaft and a stationary housing. The cylinder block is mounted in fixed roller bearings in the housing. An even number of pistons are radially located in bores inside the cylinder block, and the valve plate directs the incoming and outgoing oil to and from the working pistons. Each piston is working against a cam roller.
