MGS Industrial Speed Reducers Modular Gearing System http://www.stober.com/power/mgs.htm
The MGS, or Modular Gearing System developed by Stober design engineers, is the foundation to this new line of products. It is comprised of interacting, highly engineered components such as gears, housings, input and output flanges, motors, etc.
SMS Industrial Speed Reducers ServoFit™ Modular System http://www.stober.com/motion/servofit_modular.htm
The SMS™, or ServoFit™ Modular System developed by Stober design engineers, melds the already successful MGS™ line of constant ratio reducers and the ServoFit line of planetary gearheads. The new members of the ServoFit™ family are especially designed to fit all your servo needs in applications where the compact size of a planetary gearhead is not needed. With this product expansion Stober Drives offers the world's largest variety of servo reducers.
ServoFit Gearheads ServoFit Gearheads http://www.stober.com/motion/planetary_gear.htm
Based upon Stober’s 60 years of precision gear development, manufacturing, and application experience. ServoFit precision planetary gearheads provide exceptionally precise, cool and quiet operation at speeds up to 6,000 RPM. They are designed for use with popular brands of servomotors to reduce motor speeds and multiply torque in high performance applications. These gearheads are ideal for applications such as robotics, material handling, packaging, machine tool, medical equipment, semiconductor manufacturing, aerospace equipment, printing and other applications which require precise, cool, and quiet operation.
ComTrac Drives ComTrac Drive http://www.stober.com/power/adjust_speed.htm
You're probably already aware of the many common sense advantages offered by traction-type adjustable speed drives like the ComTrac drive. When compared to mechanical belt-type, or electrical adjustable speed drives, traction-type drives offer: Often, a lower initial cost. Few worries about motor over heating during low speed operation. No motor brushes to replace or communicators to score. Very compact and lightweight when compared to other mechanical drives. Simple design with few rotating components to wear or replace. Easily serviced by semi-skilled personnel. Low maintenance. Doesn't need to be cycled through its speed range to prevent component damage.
