The RD-E combines the high performance and extreme precision of the component type RV-E in a complete, easy to use package. By utilising the patented 2-stage cycloidal technology the RD-E can supply large torque, high-ratio and significant shock-load capabilities with extreme precision and excellent quality. The reducer also utilises a set of large, internal angular support bearings that provide large moment capacities and negate the need for external support devices - reducing design time and installation costs.

The Candy Differential, DIFF Series, is a precision timing mechanism used to advance or retard the rotary position of machine components. Installed in the drive train, these infinitely adjustable phase transmissions may be manually or motor-adjusted, while running or stopped. With the control shaft stationary, input and output shafts rotate in a 1:1, counter-rotating relationship. When a rotation is applied to the control shaft, a differential action occurs between the input and output elements making the DIFF Series ideal for positioning applications.
This unique modular design allows for a variety of accessories and mounting configurations, providing unmatched application flexibility. Through-shaft or single-shaft right angle box attachments are available to turn corners. Shaft reversing boxes are available making same-shaft rotation possible. The DIFF Series may also be fitted with a control motor allowing for remote adjustments.
The patented DIFF Series represents the latest in engineering development and is ideal for both machine retrofits and new machine designs.

The ZF-Ecolift types RME 310 and 410 are designed for passenger and service elevators. The revolutionary design for use in rope elevators, has distinct advantages over previously used gearboxes. Instead of using a worm gear, ZF-Ecolift benefits from the inherent advantages of two-stage planetary gears to transmit motor power to the sheaf.
ZF-Ecolift fulfils the technical regulation for elevators (TRA 200) TRA 220-229 and the European elevator standard DIN EN 81. ZF-Ecolift is suitable for motor speeds of 1000 rpm, 1500 rpm (standard speed) and 3000 rpm. In frequency inverter applications, speed can be increased or decreased referencing the standard speed. This makes using multiple sheaf sizes to achieve different speeds obsolete. Optimized gear tooth shape ensures long-lasting, wear-resistant performance. Extensive lifetime durability tests prove the consistent load capacity of ZF-Ecolift

The new HFUC Series component sets are a result of the continuous development of Harmonic Drive precision reduction gearing. In comparison with standard gears, the new HFUC series features a shortened Flexspline, which results in an important reduction of the axial length. The high performance IH tooth profile provides significantly increased torque capacity compared to gears incorporating the traditional involute gear tooth profile.
Advantages:
- High torque capacity
- Excellent positioning accuracy and repeatability
- Compact design
- High single stage ratios
- High torsional stiffness
- Zero backlash
- High efficiency
- Easy installation and assembly

Brevini's range of mixer drives are planetary gear units modified to meet the operating requirements of water conditioners and of mixers in chemical, ceramic and paper producing industries. The mixer drives combine the traditional advantages of Brevini's planetary technology - compactness and high efficiency - with the characteristics of strength and reliability.
The flexibility of the mixer drive design provides users with a number of construction options, including in-line and right-angle configurations, and the facility to directly mount a motor to the gearbox via a flange. Alternatively, a male input shaft configuration may be used with connection effected by a flexible coupling or pulley.
