E. Longmeadow, MA –Motion Control – Save time and energy by ordering one or more MinutemanTM M-SRBT Twin Pillow Block Linear Rail Assemblies from LM76. Recognized by engineers, machine builders, and retrofitters, the MinutemanTMSeries of Teflon® composite bearings from LM76 are ideal for applications that involve linear, rotary, and/or oscillating motion. The self lubricating Minuteman Series composite bearings can handle 10 times the load, has a very low coefficient of friction, dampen vibrations, tolerates shock, and are lower in cost than that of conventional linear ball bearings.

E. Longmeadow, MA – — Motion Control – Application Story – When an aftermarket manufacturer of off-road steering and suspension systems needed an upper ball joint bearing, they called LM76. These systems are purchased by off-road vehicle owners who want to upgrade their OEM steering and suspension units for hard-hitting environments. Pounding, shock, sand and debris are all part of the mix when it comes to extreme off-roading and LM76 Black Racer bearings are right at home. According to company engineers, after a year of brutal testing, Black Racer met all design goals and exceeded expectations.

Motion Control – FDA/Dairy Washdown System

E. Longmeadow, MA – — Motion Control – Application  – Dairy machinery manufacturers are under intense scrutiny by FDA inspectors when it comes to FDA material and caustic washdown compliance. Recently, LM76 was called by a large US dairy packaging company to review a problematic portion of their filling line. After each shift, the filling line is washed-down, has a caustic foaming agent applied to kill bacteria and then is final rinsed. The caustic foaming agent was destroying – literally eating – the aluminum shaft supports while shafting exhibited pitting and showed signs of minor corrosion. Additionally, there were areas where product got trapped and these locations were havens for bacterial growth. Because this system was in-place and our customer was the end-user, LM76 engineers had to use direct drop-in replacement com¬ponents. What to do?

E. Longmeadow, MA  — Motion Control  – Linear Motion – Lubricating Stainless Steel and Self-Aligning Linear Ball Bearings has never been easier! “New Design” pillow blocks and flange blocks from LM76, features a lubrication fitting, and an alignment set screw in the pillow blocks and flange blocks, and the Stainless Steel and self aligning linear bearings are modified by having an alignment flat ground on the bearings’ outer shell and drilling a hole through the outer shell.

Lubricants can then be pumped directly inside of linear ball bearing races without having to remove the bearing from the shaft. The Pillow and Flange Blocks also have been designed to accommodate an encapsulated ETX Scraper Seals that prevents contaminants from getting inside the bearing and retains the lubricant in the bearing.

Sometimes, an application leads you to an immediate, off-the-shelf solution – like this one. Harvesting bee honey is a seasonal opportunity and these systems are hauled across the country to make it happen. They need to be all weather, tough and maintenance-free. The next time you take some honey and put it in your tea, think of us – LM76.

Motion Control – CERAMICSPEED Bearing Units Are FDA Compliant!

Motion Control – Ceramic Radial Bearings are FDA Compliant

E. Longmeadow, MA – LM76 is continuing to expand its FDA compliant radial and linear bearing product lines. CERAMICSPEED Bearing Units are the latest additions. Bearings used in the food and beverage industry have to be reliable, easily cleaned, and require only minimal maintenance. CERAMICSPEED Bearing Units featuring FDA-approved Si3N4 (Silicon Nitride) balls have extremely long service life as Si3N4 balls are 2 times harder than steel balls and 4 times smoother. This means, CERAMICSPEED Bearing Units handle higher loads with less friction, resulting in longer life of the balls and the race.

To: OEMs “Tooling Up” for Urgently Needed Medical Products! Use FDA Compliant Off-the-Shelf Linear Motion Components!

LM76

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.

Pegasus Series 1 Linear Bearings – For When A Linear Bearing Simply Cannot Fail!

Motion Control - LM76 Pegasus Linear Ball Bearing!

Motion control - LM76 Logo

E. Longmeadow, MA Motion — Control Components – Linear Motion – 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 motion control 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.

Silicon Nitride was selected for the balls because it is: 40% lighter than steel, inert to chemicals (vapors, sea water, caustic washing and sterilizing solutions), capable of higher speeds and higher loads: (RC78 hardness), FDA compliant (used in surgical instruments), and does not corrode or support electrolysis.

The shell, bearing retainer and end caps are made from 440 Stainless Steel and coated with Armoloy TDCTM(Thin Dense Chrome). Armoloy is a hard (78Rc), coating with a micro-nodular surface texture. The coating’s nodular finish reduces the amount of surface area in contact with the SiNi balls reducing friction and extending life.

Pegasus Linear Bearings are available 2 series (closed and open), and in 4 sizes (1.000″, 1.250″, 1.500″ and 2.000″). Dynamic load rating for these bearings are: 1.000″ 220 lbs, 1.250″ 352 lbs, 1.500″ 490 lbs, and 2.000″ 858 lbs. Bearings are designed for zero clearance on Class L linear shafting. For maximum performance we recommend LM76 Case Hardened 440 Stainless Steel shafting with ArmorloyTM coating.
