ServoBelt™ Product Announcement

A new line of linear modules using our patent pending ServoBelt™ drive technique is now available. Zero backlash, high stiffness and industry leading repeatability make this technology a true contender to replace linear motors in demanding applications requiring high speed and low settling time.

At the heart of the technology is a static bonded lower belt that meshes with the upper dynamic belt so that the active belting under tension is only a few inches long. Servo tuning can have much higher gains than conventional belts, because stiffness is high and does not change throughout the travel.


  • Actuators and stages are configurable as multi-axis Cartesian and gantry robots.
  • Modules may be purchased as single axis elements for your OEM equipment or as a completely integrated multi-axis robot with amplifiers, cables and optional linear encoders.
  • Multiple carriages can be supplied for independent motions on the same axis, and dual motor carriages are available to double our standard linear forces.
  • Five motor choices in both NEMA 23 and NEMA 34 frame sizes for easy configuration, or units are available for mounting of third party motors.
  • All chassis are based on Bosch T-slot extrusions for ease of integration and a wide array of mounting hardware.
  • Unlimited length for large format applications.


  • Accelerations in excess of 4g.
  • Speeds to 5m/s.
  • High performance polyurethane/steel reinforced belt
  • Single motor peak forces to 880N, continuous forces to 300N.
  • Out of the box accuracy to ±60µm.
  • Unidirectional repeatability to ±10µm, bi-directional to an amazing ±40µm.
  • All bearings Lubed-for-Life, no maintenance required.
  • Direct-Drive three phase servo motor available in five sizes.
  • 16,000 and 20,000 CPR rotary encoders standard.
  • Optional Renishaw linear encoder for 10x better repeatability and accuracy
  • Optional integrated limit sensors, infinitely adjustable
  • Anodized aluminum construction with SS hardware

About Bell-Everman

Bell-Everman Inc. was founded in 1991 with the goal of creating motion devices that offer best-of-class precision, quality and value. Since then, our motion control technologies have been incorporated into a wide variety of automation and metrology systems—including those found in the aerospace, biomedical, semiconductor, electronics assembly, laser and water jet cutting, CNC machining and packaging industries. Today our product line comprises precision linear bearings, linear motion positioning devices, rotary stages and complete multi-axis robotic systems. All of the products are designed and built in our own facility in Southern California.
