Gear pumps and motors built in three pieces with an extruded body in high resistance aluminium alloy.
The wide choice of shafts, flanges and ports, in compliance with all international standards (SAE, DIN and EUROPEAN) allow for their use in an infinite variety of applications.
|
|
Gear motors made of cast iron in two pieces.
A rigid and compact structure that makes it possible to incorporate a number of functions in a limited space.
Wide range of displacements: from 0.30 in³/rev (4,95 cm³/rev) to 9.20 in³/rev (150,79 cm³/rev) available in groups 20, 30 and 40
Max. peak pressure up to 4785 psi (330 bar)
Max. speed up to 4000 min-1
|
|
When you need to produce and control high pressures, forces and torques permanently for mobile applications, then there are some pre-conditions:
- robust, service-friendly technology
- small size
- low weight
- as flexible multiple use of a component as possible
- easy handling and operation
The KRACHT mobile hydraulic components meet these requirements exemplarily. A glance at the technical data will convince you.

External gear motors, series APM
The essential components of series APM external gear motors are an aluminium alloy body and two gearwheels supported by plain bearings.
The front flange can be the SAE standard, or the British or German OEM patterns.
Particular attention has been focussed on the design of the shaft seal, which is often affected by back-pressures.
Advantages
- High overall efficiency thanks to optimised hydraulic compensation
- Optimum quality/price ratio
- Customised models can be built for specific applications
- Low maintenance requirements, even in heavy-duty operating conditions
- Various components and accessories are available for radial/axial loads, integral anti-cavitation valve, etc.

Planetary Gearboxes
Fully assembled option with:
– MDrivePlus
– NEMA rotary motors
Planetary gearboxes can increase motor torque at lower speeds, enable better inertia matching, and produce finer positional resolutions.

GP 22 S and GP 32 S modular spindle drives.
Mechanical engineering often faces the task of converting rotational movements into powerful linear movements. The associated development costs can now be cut dramatically by using modular spindle drives in maxon motor's modular system. The GP 22 S and GP 32 S gearheads, specifically adjusted for spindles, are designed to withstand high loads, and the special spindle intake means that customer-specific spindles can be assembled easily which shortens supply times.
There are three different standard spindle types to choose from: metric spindles, trapeze spindles and spherical rotating spindles. The spindles are available as steel or ceramic variations and in any length up to 200 mm. Spindle nuts to match are supplied.
Gearheads, motors, encoders and controllers from maxon's standard program are used to drive the spindles. The individual components of the spindle drives are all compatible to help create highly effective drive solutions. For the time being, modified planetary gearheads are available in two different sizes, with diameters of 22 mm and 32 mm. Reduction ratios of 3.7:1 to 1093:1 provide maximum torques of 6 Nm and speeds of up to 1600 min-1. The additional axial bearings of these gearheads can also withstand powerful axial forces from the spindles.
