alpha introduced the world's first high speed inline planetary gear reducer and continues to create groundbreaking inline solutions for servo applications. From the compact precision of the TP+ to the economical performance of the LP+ and the classic solution of the SP+, alpha has an inline planetary solution for your needs.

The SP+ is the newest generation in classic precision. Always the most popular of the planetary range, the SP+ products are designed for a variety of applications, providing quiet operation and optimal axial and radial loading capacities. For high speed applications, alpha offers the SP+ High Speed® as the best alternative. All SP⁺ gearheads are 100% factory tested according to the stringent alpha cycle.

The TP+ is packed with exceptional precision in an intelligent, compact solution, offering alpha customers revolutionary, space-saving machine designs. Key performance characteristics of the innovative TP+ are low backlash and high torsional stiffness combining to create superior positioning accuracy, even in the micro range. This compact precision solution from alpha's range of innovative products achieves substantial more torque than other alternatives.

The economic precision products, alpha's LP+ & LPB+, are reliable and – thanks to a unique lubrication concept – maintenance-free for their entire service life. Focused on less demanding applications, these gear reducers offer outstanding efficiency with low torsional backlash.

The LPB+ offers the option of adding an integrated geared pulley drive system. The belt pulley eliminates the need for a right angle gearbox, couplings and/or additional bearings - in turn, reducing cost, increasing performance, and reducing parts and engineering time for the system.

The newest addition to the inline series is the alphira® - the basic precision. Fast, flexible, efficient – three attractive attributes to win customers. Packaged in a lightweight aluminum case, alphira® is exceptionally precise, power-dense and maintenance-free.

Ideal as a component of servo and stepper motor applications, alphira® is optimally equipped for the job, with the single-stage version of this new low-backlash planetary gear reducer achieving a maximum backlash of 20 arcminutes in size 40 and larger. In terms of reliability, efficiency and precision, alphira® is every bit as impressive as its older brothers in the rest of the alpha family.

The innovators in servo gear technology, alpha continues to provide solutions which are the most advance in the industry, making machines run faster, more efficient and more productive. alpha's product range includes several series of precision gear reducers, servo couplings and various rack and pinion systems to fit any application.
