Bosch Rexroth UPE2-1X/1, 1R1, 25/4ANT-1V+04101301 Part No. R904101302 Clamping and Drive Module Distribution

R904101302 Bosch Rexroth UPE 2 clamping and drive modules constitute a complete drive system that is ready for connection upon delivery. They are used to supply hydraulic oil to the hydraulic circuit. Due to thermal load considerations, the clamping and drive modules operate in short-time and intermittent duty modes. The duty cycle is selected based on power output and environmental conditions so that the maximum permissible operating temperature of 80 °C is not exceeded. The clamping and drive module basically consists of an aluminum housing, a pump (radial piston pump or external gear pump), and an oil-immersed motor. The stator of the oil-immersed motor is pressed into the aluminum housing. It transfers the heat from the windings directly to the outer wall of the aluminum housing. For installation, four through-holes for mounting screws are provided in the bottom of the tank. The clamping and drive module operates in a vertical installation position. Optionally, the UPE 18 clamping and drive module can be equipped with electronic monitors for oil level and oil temperature monitoring, air filters, and complete hydraulic control.

R904101302 Overview of Accessories for Clamping and Drive Modules

1) Basic module "G": – Basic module with integrated relief valve for simple lowering and holding pressure functions. – If basic module "G" is used, further stacking is not feasible. – For more details, see catalog "Control Block Types for Clamping and Drive Modules IH15A". 2) Directional valve module "W" 1): – Allows control designs using valves with porting surfaces conforming to DIN 24340 form A. – The number of directional valve modules depends on the discharge volume and pump displacement. – For more details, see catalog "Control Block Types for Clamping and Drive Modules IH15A". 3) Seat valve module "S" 1): – The basic composition of the seat valve includes: • One relief valve block. • One or several control blocks. • One end block. – Control is designed according to the specific application. – The number of seat valve modules depends on the discharge volume and pump displacement. – For more details, see catalog "Control Block Types for Clamping and Drive Modules IH31A". Directional valve modules and seat valve modules can be combined!

R904101302 Air Filters and Oil Trays for Clamping and Drive Modules

Air filter (optional): We recommend using an air filter when operating the clamping and drive module in heavily contaminated environments. During installation, the connection between the air filter and the engine intake pipe, whether via flange, rubber hose, or direct connection, must be tight and reliable to prevent air leaks. Rubber gaskets must be installed on both ends of the filter element. The wing nuts securing the air filter cover must not be overtightened to avoid crushing the paper filter element. During use, protect the paper-core air filter from rain, as absorption of large amounts of water significantly increases intake resistance and shortens service life. Furthermore, paper-core air filters must not come into contact with oil or fire. Oil tray (optional) (dimensions in mm): Size 3 and Size 4 Material No. R901109231, Size 5 and Size 7 Material No. R901109235, Color: RAL 7051 "Light Gray."
