The Temposonics MH sensor provides CANbus-based position feedback. As a slave device, it is connected directly to the fieldbus. In addition to displacement, it also determines the velocity during position change, in order to measure and control the movement behaviour of the cylinder. This is particularly important with mobile machines, which realise an overall movement using several independent hydraulic cylinders, which require synchronization. As the velocities and current position difference between two or more cylinders are continuously measured, the faster cylinder can be slowed down to avoid varying velocities, therefore, reducing the mechanical load and permitting improved response to load changes. It can be used in harsh environments where shock, vibration and dust provide challenging conditions. This sensor can handle vibrations of 30g(av) and withstand single shocks up to 100g. Its magnetostrictive sensor technology offers non-contact operation for years

The SR and SV roller screws are able to withstand far heavier loads than traditional ball screws, while maintaining high levels of precision and stability at all times. This is achieved by transferring the load from the nut to the screw shaft through threaded or grooved rollers, which provide stronger contact points than ball bearings, providing reliability and long low maintenance service life for machinery. The range consists of the SR planetary roller screw and the SV re-circulating model. The SR is a robust steel device, featuring threaded non-recirculating rollers and a long lead symmetrical nut allowing a shock-resistant high-load carrying capacity of up to 12,000kN. Likewise, the recirculating SV roller screw offers high positional accuracy and fine resolution capabilities, with precision and reliability achieved through its compact 1mm leads, which minimise drive torque and improve resolution.

The Predator is a robust V-belt with high load capability, specially designed for use on problem drives that need to perform well in harsh environments and on demanding applications. Using aramid tensile cords this V-belt has a high shock load resistance and virtually zero stretch. This means less frequent retensioning and increased productivity. A specially treated double fabric cover provides abrasion resistance that makes them withstand debris, punctures, slippage and shearing forces. The outer surface of the double fabric cover is manufactured in a bareback (non-rubber impregnated) construction. This enables the belt to slip under heavy shock and impulse loads without generating excessive heat. It features a multiple layer tie band that provides
good lateral rigidity to prevent belts from turning over or from coming off the drive.

The NEP roller chain employs a combination of three layers of surface coating, combining a highly resistant base layer that bonds a harder wear-resistant coating onto the chain rollers where they come into contact with sprocket teeth. An additional tough external coating is then used to cover and seal all the other component surfaces with further corrosion protection. Thanks to this the chain can be used in wet conditions without corroding. Moreover, the chain is RoHS-compliant.

The threephase gear motors come with a motor rating of 0.37KW, complete with attached frequency converter (FC) in an aluminium casing (protection class IP55). There is no need for the external cables and fitting is that much faster. The electrical connections to the motor are located within the enclosed metal casing and both the power loss of the converter and the voltage load of the motor are reduced. Due to the modular structure of the system, only the relevant component needs to replaced if the gear unit, motor or FC becomes defective. The FC works with a cycle frequency of approx. 10kHz (can be switched over to 16kHz). It is designed for 2-quadrant operation (driving in both rotary directions). Braking is possible up to the power rating that corresponds to the power loss of the motor, with the motor being operated with over-excitation during braking operation (with overvoltage), i.e. the motor power loss will be greatly increased during braking operation.

The DP4 bearings are designed to withstand the high pressures generated by downsized equipment. Rare-earth fibers in the coating enable them to withstand up to 10MPa x m/s lubricated, speeds exceeding 2.5m/s, loads up to 250MPa and temperatures from -200 to 280°C. Exceptional resistance to both flow and cavitation erosion make the bearings suitable for start/stop applications. These bearings perform well dry under light-duty conditions. Because they are lead-free, they are also suitable for use in applications where corrosion might occur. Industrial applications include lifting equipment, hydraulic pumps and motors, pneumatic equipment, medical equipment, textile machinery, agricultural equipment, scientific equipment, drying ovens and office equipment. The structure of the bearings consists of a rigid steel backing, to which is bonded a porous bronze sinter interlayer impregnated and overlaid with a filled PTFE bearing layer.
