E. Longmeadow, MA – Two new series of high speed, low cost, compact linear guide systems called, “Speed Guides,TM” have been introduced by LM76. The Speed Demon OSG type and Speed Demon SG type linear guide systems are designed for speeds up to 10 m/sec. (32.8 ft/sec.), accelerations to 50 m/sec.2 and loads up to 5600 N. (1259 lbs.). These quiet, low profile guide systems are ideal for: High speed assembly and sorting operations, pick and place robots, industrial, office, and packaging machines, vacuum applications, and medical equipment (including patient care devices).

Engineering Edge - Honey Application

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.

Motion Control – ETX Unitized Pillow Block Bearings Are FDA Compliant!

We needed a bearing block that would be FDA compliant, washdown compliant and…be able to take a radioactive environment. We made a unitized bearing and mounting block combination that met application requirements. You won’t find this an any catalog!

Motion Control Application – How Do You Move Articles of Antiquity?

Very Carefully With A High Load Rail System from LM76!

E. Longmeadow, MA – — Motion Control Application -The Boston Museum of Fine Arts (MFA) has to move articles of antiquity from one location to another. In this instance, they are moving a 5000 year old relief (hieroglyphics) weighing 8000 pounds to a new location in the Museum. Here is a frontal photo of the Relief from The Tomb of Senenuka.

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 -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.

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

Motion Control- ETX Linear Bearing/Pillow Blocks

Motion Control Bearing/Pillow Block for Radioactive Environments

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.
