Motion Control -What To Consider When Specifying A Linear Slide

Motion Control – Tutorial

Considerations when specifying a linear slide for a new or existing application.

By Mike Quinn • LM76

When a design engineer has fully defined a linear-motion application’s requirements regarding travel length, speed, force, and accuracy as well as repeatability, the next question to answer is this:

Does an off-the-shelf linear slide (or a stock linear slide from a catalog) fully satisfy the application?

Off-the-shelf linear slides are advantageous for their quick delivery and lower cost than that of custom components. No wonder most linear-motion designs do in fact employ off-the-shelf linear slides from various component and system suppliers.

E. Longmeadow, MA –Motion Control – LM76 is the Exclusive North American Distributor of a new high speed integrated bearing and drive system featuring +/- 5 micron repeatability, and zero backlash! This new X-Axis BE125-10 Open Screw Drive System sets new standards for: Length of travel, speed, and precision for Cartesian Robots (robots that move in X,Y and Z axes according to Cartesian Coordinates also know as rectangular coordinates) and single axis linear stages!

The new X-Axis BE125-10 Open Screw Drive System is a compact linear stage measuring 125 mm (4.921 in.) wide x 86 mm (3.386 in.) high x 4391 mm (172.874 in.) long and can handle dynamic loads to 500 kg (1102 lbs). The standard stroke length is 4000 mm (157.480 in.) and custom stroke lengths to 10 m (32.8 ft) can be specified.

This new drive system consists of a precision ground open screw and two pre-loaded radial ball bearings additionally the open screw drive system is supported by bearings spaced every 250 mm that prevent screws as long as 10 m from whipping even at 5000 rpms. This is in contrast to a closed screw system (ball screw and nut) which are more limited as to length of travel and rpms.

Shafting options include: Solid and hollow Class L RC60, 300 series stainless steel in lengths to 12 feet. FDA/USDA/3A-Dairy compliant, shafting features: Excellent corrosion and chemical resistance, custom machining to print, pre-drilling and assembly.The guide system consists of two parallel shafts and 8 preloaded radial bearings. In addition to smooth motion, low vibration, low noise (less than 68db at 3000 rpm), and minimal heat generation the BE125-10 Open Screw Drive System is capable of travel speed up to 1.7 m/sec (5.5 ft/sec). and pitch and yaw accuracy over 4000 mm (157.480 in.) of travel is just +/- 0.02 mm (0.00079 in).

Get the high precision X Axis BE125-10 Open Screw Drive System for higher throughput, and guaranteed longer life in: Pick-and-place, sorting, packaging, assembly, machining, and testing applications. This complete linear stage and drive system is easily integrated in new and existing applications.
