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.

Linear Motion – FDA/USDA/3A-Dairy Compliant ETX Scraper Seals for Linear Bearings Used In Food Processing Applications!

Motion Control – ETX Scrapers and Seals

E. Longmeadow, MA – Motion Control Components – Linear Motion – LM76 has introduced FDA/USDA/3-A Dairy compliant, snap-in ETX Scraper Seals for linear bearings. Machined from Ertalyte® PET-P, ETX Scraper Seals have high strength, excellent wear resistance, low coefficient of friction, and excellent dimensional stability at higher temperatures than seals from other materials. Designed with a slight interference fit between bearing ID and shaft, ETX Scraper Seals prevents contaminates and debris from migrating beneath the seal as it scrapes the shaft surface.

E. Longmeadow, MA –Motion Control – LM76 has developed the most corrosion resistant linear bearing available. In space, deep under the sea, or in the harshest environments, when there can be no “Plan B,” Pegasus Series 1 Linear Ball Bearings can be counted on to perform. In some applications linear bearings will not move for days, weeks, months or even years, however, when called on to perform they must work as if they just came out of the box. LM76’s Pegasus Series 1 Linear Bearings feature Silicon Nitride (SiNi) Ceramic Balls in a shell with retainer and end caps all made from 440 Stainless Steel and then ArmorloyTM coated.

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 Components – Linear Motion – In dealing with the COVID-19 pandemic many companies have volunteered or been requested to produce urgently needed medical products such as: Masks, gowns, and ventilators. “Tooling Up” quickly to produce medical grade products for some companies can bring challenges. In addition to needing FDA compliant materials that will be used in the actual masks, gowns, and ventilators, the tooling used to manufacture these products may also need to meet FDA compliance standards. Depending on the product being manufactured, the tooling may need to be: Washed down using caustic chemicals, cleaned with high pressure steam, or sterilized with high Intensity Ultra Violet light or radiation.

Ordering custom FDA compliant linear motion slides and XYZ stages can result in long delays. As an alternative, many companies have linear motion slides in stock for immediate delivery, however, they may not be FDA compliant. In many cases it is the bearings that are not in compliance. LM76 manufactures several types of FDA compliant linear bearings and pillow blocks that are drop-in-replacements for existing bearings. FDA compliant bearings and pillow blocks from LM76 will not trap contaminating debris and can be thoroughly sanitized following Sanitation StandardOperating Procedures (SSOPs). SSOPs are detailed schedules and procedures specifying what to clean, how to clean, how often to clean, and the record keeping used for monitoring.

A helpful component selection guide from LM76, “Linear Bearings, 6 Simple Steps – FDA Compliance, Wash Down Compliance,” details the linear motion components available from LM76 that are FDA/UDSA/3A-Dairy compliant. Included are: Foodstream electroless nickel plated pillow blocks, PTFE lined stainless steel bearings, ceramic coated linear bearings, self-aligning corrosion resistant linear ball bearings, and Thomson® Super SmartTM corrosion resistant, self-aligning, high load linear ball bearings, and solid ETX pillow block/bearings. Shafting to compliment the type of bearing selected includes: Class L Stainless 303/304/316, 440C case hardened stainless, Rc 60 case hardened steel with an Armoloy coating and also Rc78 Class L for enhanced hardness and wear resistance. End blocks and shaft supports that have a ceramic or electroless nickel coating are also available, as well as new ETX Scraper Seals that prevents intrusion of contaminates adding another line of defense.

LM76 also designs and custom builds linear slides from Stainless Steel and other FDA wash down compliant materials.
