    You can combine our radial-piston motor series

    KM 11 to KM 110 (Radial-piston fixed-displacement motors)RM 80 N to RM 250 N (Radial-piston fixed-displacement motors)RM 250 X to RM 3150 X (Radial-piston fixed-displacement motors)

    and our axial-piston motors as well as all commercially available IEC electric motors with our 1- to 4-speed planetary gears. In addition, you can install spring-pressure multi-disc brakes, which are required for holding static loads, between motor and gear.

    We differentiate between coaxial and bevel gear motors:

    While coaxial hydraulic gear motors have a small diameter,they often need more lengthwise installation space than bevelgear motors. The latter have a short length and are often used as wheel drives because of their ground clearance.

    The gear motors described here have been designed for the following torques:

    E standard series Coaxial Continuous torques of 0.3 kNm up to 19 kNm Bevel Continuous torques of 1.3 kNm up to 19 kNm

    The standard series consists of gear sizes 010, 020, 030, 045, 065, 090, 150, and 250. They vary with regard to admissible loads and are available with the following output variants:

    Z Cylindrical output spigot with DIN 6885 feather key connection Available for sizes 010, 040, 046, 090, 150, 250

    MRZ Cylindrical output spigot, reinforced, with DIN 6885 feather key connection Available for sizes 010, 020, 030, 045, 065, 090, 150

    K Cylindrical output spigot with DIN 5482 splined shaft teeth Available for sizes 010, 040, 046, 090, 150, 250

    MRK Cylindrical output spigot, reinforced, with DIN 5482 splined shaft teeth Available for sizes 010, 020, 030, 045, 065, 090, 150

    H DIN 5482 hollow shaft teeth Available for sizes 010, 020, 030, 045, 065, 090, 150, 250

    FS Slip-on design with torque support and shrink-fitted disc Available for sizes 010, 020, 030, 045, 065, 090, 150, 250

    Overview of all output variants (displayed model is RM 160NHAF-ED2065.....)

    K / MRK

    Geared output shaft as per DIN 5480 / 5482. Reinforced bearings makes it particularly suitable for additional radial and axial loads.

    Z / MRZ

    Cylindrical output shaft with DIN 6885 feather key. Reinfor- ced bearings makes it particu- larly suitable for additional radial and axial loads.

    H Geared hollow shaft as per DIN 5480 / 5482. Not suitable for receiving radial and axial forces. Aligned installation is paramount.

    FS

    Slip-on gear motor with torque support and hollow shaft with shrink-fitted disc connection for connection free from play with the counter shaft. This layout is guaranteed to be free from tensioning as the freely moveable torque support follows all deflections

    Type designation

    The exact gear name is composed of the type code for the series and the design (EM, ED, ET and EQ for 1-, 2-, 3-, and 4-speed coaxial gear and/or EC for all bevel gears regardless of the number of speeds), the number of speeds (1, 2, 3, or 4), the size (010, 020, 030/040, ...), the type of output (Z, K, ....), and the gear ratio

    Example: ED 2065 MRZ - i = 22,39 ED Coaxial gear (2 speeds) 2 2-speed gear 065 Size 065 MRZ Shaft design (see above) - i = 22,39 Effective gear ratio

    EC 3090 Z - i = 50,55 EC Bevel gear 3 3-speed gear 090 Size 090 Z Shaft design (see above) - i = 50,55 Effective gear ratio

    The full type designation of a hydraulic gear motor and/or a hydraulic brake gear motor is always composed of the type informati-on of the hydraulic motor, the multi-disc brake (if required), and the gear. For example,
