The SP + and SP + High Speedģ series planetary gearheads are featured in a new 32-page guide from Alpha Gear Drives. The guide includes such technical information as data and diagrams on the gearheads' accuracy, acceleration, noise, and backlash characteristics. The new SP+ series has several new features, including noise levels lower than 64 dB(A), a high torque capacity, and a longer lifetime because of improved torsional rigidity. The SP+ High Speed version can run up to 4,500 rpm in continuous operation. To find out more, visit www.alphagear.com.
