THE Alpha SP+ low backlash planetary gear reducers, available from Treotham Trading , are designed to match the high performance characteristics of ac brushless servo motors.

An optimum gearing geometry guarantees up to 97% efficiency with input speeds up to 6,000rpm.

Operating on a high level of power density, smoothness, low weight and high torsional rigidity, the SP+ works with reduced torsional backlash - less than one arc-minute of backlash on request.

Vibration of the unit is extremely low, thus affording a significant level of precision in a standard gear head to dramatically increase positioning accuracy.

At 6dB(A), the SP+ is about four times quieter than its already quiet forerunners in the SP line.

Alpha introduced new seals developed specifically for the SP+, with both material and geometry optimised to provide true IP65 (optional IP66) protection.

In addition, the output bearing capacity has been optimised to surpass anything in its class.
