The SP+® and /SP+ High Speed Planetary Gearheads are smooth running helical geared units, with the noise emission of the SP+® being 6 dB(A) lower than that of our already quiet SP line, making the SP+® four times quieter still.  What's more, vibration is dramatically reduced.  The SP+® provides a new world of precision in a standard gearhead.  We've reduced the torsional backlash, and can further offer you less than one arc-minute of backlash on request, dramatically increasing positioning accuracy.  alpha had new seals developed exclusively for the SP+®, with optimized material and geometry, to provide true IP65 (optional IP66) protection.

In addition, the output bearing capacity has been improved to surpass anything else in its class.  Thus, the The SP+® provides a world-class lifespan.  Regardless of how your The SP+® is mounted, it always has the same amount of oil, eliminating the need to specify mounting position when ordering.  Although its predecessor already delivers exceptional performance, we have increased the maximum acceleration torque of the The SP+® even further to provide higher performance from your machine.  Like its predecessor, The SP+ High Speed® provides superior performance for high duty cycles.  It can be run continuously, has a long service life and with our patented integrated thermal linear expansion compensation system it gets no more than lukewarm even under the highest stress.
