motion control - LM76 Linear Motion Bearings

 

LM76

E. Longmeadow, MA Motion — Control Components – Linear Motion – Available off-the-shelf, cylindrical, self lubricating, sintered bronze bearings from LM76 feature: Very high precision (e.g +2μ to +12μ for 2mm ID bearings), high load capacity (100kg/sq cm), high speed 30,000 rpm) and rapid oscillation capabilities, low/high temperature (-60OC to +230OC), very low coefficient of friction (0.02), and low noise. These reliable, economic bearings are available in metric sizes (2 mm to 100 mm ID by 2 mm to 120 mm long) and have applications in: Appliances such as washing machines, exercise equipment, portable machine tools, toys, motors, packaging machinery, garden tools and machinery, vibration damping, and automotive equipment such as alternators.

These lifetime Self Lubricating bearings are impregnated in the sintering process with a lubricant to suit the application. Sintered bearings are available in lead free Bronze, bronze alloys and Iron. Additionally: Flanged bearings (IDs 3 mm to 60 mm by 4 mm to 60 mm long) and precision (ID tolerance ISO H7) Spherical bearings, with or without a collar, (IDs 4 mm to 12 mm by 10 mm to 23 mm ODs) are available, as well as custom sizes and designs. Because of the very low coefficient of friction these bearings show no wear after many thousands of hours of use. Standard metric cylindrical and flanged oil impregnated bearings are typically shipped from stock, Custom bearings (ID, OD, flange size, and length) can be ordered as well as special purpose alloys. Alloys include: sintered bronze, iron sintered bronze, ParaliteTM (non-migrating lubricant), and TriboloyTM (chromium, nickel, cobalt alloy for temperatures over 1000O F). TriboloyTM sintered bearings are resistant to corrosion, erosion, abrasion, and galling, and even at high temperatures they are resistant to oxidation.

The Engineering Edge – History of Ceramic Bearings.

For 42 years LM76 has been offering innovative solutions to problems!


THE SOUL OF A NEW IDEA In 1976, Warren Hamilton, The General Manager of J.C. Tarbell Associates,  an internationally recognized designer of plain (sleeve) bearings was asked by a customer to solve a linear ball bearing failure. At the time, Warren and his team spent most of their efforts on traditional rotary, sleeve bearing design. Applications like a revolutionary sintered, high temperature (700F+), self-lubricating aircraft engine stator vane bushing made from nickel, chromium and cobalt – eventually used in every F404 engine employed on the new F-18 Hornet – America’s new topline fighter. Getting back to the linear ball bearing issue… Warren studied the linear ball bearing failure and set-out to find a solution. The linear ball bearing was failing because of too short a stroke coupled with rapid oscillation. Up until this time, there was no solution. In 1976, the idea of ceramics was in its infancy relative to industrial designs. Warren had an idea, using an aluminum substrate and applying a ceramic coating to it might work. While struggling to find an answer, Warren had a design epiphany and the ceramic coated linear bearing – and LM76 (Linear Motion 1976) – were born. “And now you know – the rest of the story.”

The Engineering Edge – Application – ETX Pillow Blocks!

the engineering edge application

This was a troublesome application. This system is completely submerged in radioactive water at a nuclear power plant. So no Teflon, no seals, no lubrication – nothing that will degrade in a radioactive environment. The majority of components are stainless steel – except for our ceramic coated/supported shafting and our special, designed for this particular application/never made before, ETX self-lubricating linear blocks. As you see, there is a circular saw which cuts metal-mesh filters which need to be replaced every few months. A big solution for a pressing application.

How Would You Position Components Of An Experimental Reactor Vessel Weighing 33 Tons?

Easily …   … Using Custom made LM76 Jet Rail Bearings and Shafting!

When a privately funded research company was ready to move from their original Proof of Concept to a sustainable fusion reactor to produce clean sustainable energy, they realized that extremely heavy components would need to be assembled and disassembled and reassembled again for design modifications and maintenance. The completed assembly would be the length of two buses and easy alignment of the individual components would be critical.

 

The main reactor, the fusion containment chamber that is capable of containing a plasma medium of 10 to 15 million degrees is made of non-magnetic stainless steel as are many of the components. The Plasma Medium could be described as a football shaped blob about 1 meter in diameter by 2 meters long. The plasma medium is injected from each end of the reactor assembly by Plasma Guns.

In addition to supporting the weight of the components, the bearings selected to move these massive loads during the construction and testing of the fusion reactor would have to be non-magnetic. Working with engineers, LM76 developed a custom 3 inch Jet Rail Bearing designed to carry both the weight of the fusion reactor and the high energy particle generators. In addition LM76 supplied precision ground, 3 inch 303 stainless steel (non-magnetic) shafting.

The custom manufactured Jet Rail Roller Blocks and 303 stainless steel shafting simplified the assembly/disassembly of the fusion containment chamber and components while ensuring critical alignment throughout travel.

This breakthrough fusion reactor is still in the experimental stage. A commercially viable reactor would need to contain 100 million degrees. Why is the project so important? Because in addition to producing sustainable energy, its only by-product is, environmentally safe, “helium ash.”.

The Engineering Edge – Linear Motion Application – Moving Articles of Antiquity!


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

Very Carefully With A High Load Rail System from LM76!

Linear Motion - Moving Articles of Antiquity using LM76 Rail System

LM76 - Linear Motion

E. Longmeadow, MA – — 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.

Part of wall from tomb of Senenuka; nine stones fitting together and including two niches; lower left piece smooth limestone; upper far left preliminary black ink sketch; right of this sketch is a complete relief showing two seated figures; central piece has large scene of seated male on the left and other smaller male figure to the right; upper far right male figure relief outline; left of this again a scene of two seated figures at a table.

Senenuka Time of Khufu or Khafre (Maybe Dyn 5?) Overseer of the Pyramid-town of Khufu, Director of King’s wad-priests, Boundary official of a settlement, etc.

The MFA contracted CBI Consulting of Boston to design the frame and fixturing. Craig Barnes, an award winning architectural engineer called Mike Quinn of LM76 to review the linear motion application. Over the course of several weeks, LM76 and design partner Todd Kanipe designed a telescoping, high load roller/linear motion rail system that won approval. According to CBI’s Keith Bouchard, the linear rail system moves very smoothly and so far meets the expectations of this program.”

Linear Motion Application – According to MFA Antiquity Specialist Jean Louis Lachevere, “All of these moves present very real dangers to the artifact being transported. In this case, we have a 8000 pound relief which already has its problems due to age and the fact that it is limestone ( limestone is very vulnerable to the atmosphere ).” Seen from the front, the relief is straight. From the back, much of the top back is gone. Thus, the back of the relief has to be plastered so the back is flat. Pins are inserted to further reinforce the relief and then it is tipped on its back. It is then moved to its new atmospherically controlled display case. LM76’s design is used in the transfer from the dolly to the mounting rails and restraints in the display case. This 36” motion is fraught with things that can go wrong. One of the considerations is the possibility of an earthquake…any problem conceivable is taken into account.

Motion Control - Moving Articles of Antiquity using High Load Rail SystemCastors and sliders at end of armature. The sliders are mounted to the castors and work like telescoping drawer slides.
