E. Longmeadow, MA –  Motion Control — When profile rail guides fail within a week bring production to a standstill LM76 was called on to supply a linear bearing system that would stand up under extreme conditions. This application story is not claiming that LM76 Jet Rail Systems are superior to profile rail guide systems. However, in this harsh environment the LM76 Jet Rail System proved to be the correct engineering option.

E. Longmeadow, MA — Motion Control – LM76 has announced the release of their new line of Radial Ball Bearings featuring ZrO2 (Zirconia) Ceramic balls. To Complement LM76’s broad range of Linear Bearings that are FDA/UDSA/3A Dairy compliant, as well as linear bearings for extreme environments; they have added Deep Groove bearings which accommodate radial and axial loads, Angular Contact bearings for simultaneously handling radial and axial loads, Spherical Bearings which are self aligning, and Thrust Bearings for high axial loads. Each of the four types of metric bearings are available in a wide range sizes.

The advantages of ZrO2 ceramic balls are: FDA/USDA/3A Dairy/Caustic washdown compliant, lighter than steel balls and can be used at extreme RPMs, they withstand higher loads without spalling, have a lower coefficient of friction, are inert to chemicals, have no magnetic signature, and are non conductive.

Motion Control Application – Open Screw Drive System Moves Heavy Sound Stage Sets Smoothly, Quickly, and Quietley!

Motion Control Application – High Speed Drive System

E. Longmeadow, MA –Motion Control Application-

Problem: Move heavy sets on a sound stage smoothly, quickly, and most importantly quietly! Ball screws specified in the original design proved unacceptable due to the limited length of travel, screw deflection which resulted in a lack of smoothness, and high noise levels. A rack and pinion was also considered but the noise level was also too high and there was no room for a gearbox. Linear motors are quiet however the cost was prohibitive, and a belt system could not handle the heavy loads.

Solution: The new Streamliner Open Screw Drive System from Winner was selected by the production company to move the heavy sets on the sound stage.

Linear Motion Control – One Piece ETX Linear Bearing/Pillow Blocks Can Be Used In Radioactive Environments!

Motion Control – ETX Pillow Block/Bearings for Radioactive Environments

motion control pillow blocks/bearings

E. Longmeadow, MA Motion — Control Components – Linear Motion – LM76 now offers one piece ETX Linear Bearing/Pillow Blocks that will not degrade in a radioactive environment! Machined from a solid block of self lubricating ETX, linear bearing-blocks have high strength, excellent wear resistance, low coefficient of friction, and excellent dimensional stability at higher temperatures As there is no other materials such as PTFE seals or lubricants these bearing-blocks are maintenance free. Custom designed for use in a nuclear power plant these linear bearing/pillow blocks travel on ceramic coated shafting (also supplied by LM76) completely submerged in radioactive water.

Designed with a slight interference fit between bearing ID and shaft, contaminates are scraped from the shaft’s surface. The low frictional characteristics of ETX have little impact on drive force. They are now available in Inch and Metric sizes.

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.
