Motion Control – Application – LM76 Jet Rail Linear Motion Bearings & Shafting
Motion Control Application – How Would You Position Components Of An Experimental Reactor Vessel Weighing 33 Tons?
Easy … Using Custom made LM76 Jet Rail Bearings and Shafting!
E. Longmeadow, MA –Linear Motion Control Application – 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.
See photo to right – On each end of the assembly is a Plasma Gun. The Plasma Guns as are all the floor lever components, are positioned using LM76 Jet Rail Bearings and shafting. The Jet Rail Bearings and Shafting can be seen near to bottom of the picture.
In addition to the reactor, high energy particle beam generators are positioned at angles to the fusion containment chamber. These particle bean generators form and suspend the plasma medium for an indefinite period of time in the center of the containment chamber. These generators have to be easily positioned – by hand – to accommodate adjustments and re-assembly.
See photo to the left – Neutral-Beam Injectors are positioned around the Reaction Chamber to position and shape the Plasma Medium. These are also moved into position on LM76 Jet Rail Bearings and Shafting.
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.”.
See photo below – The drawing below shows all the components in place. The assembly is 60 meters long and supported on LM76 jet Rail Bearings and Shafting.

Motion Control – Pegasus Linear Bearings – For the Time A Linear Bearing Simply Cannot Fail!
Motion Control – Hybrid Ceramic Ball Linear Bearings
For those times when a Linear Bearing “CANNOT” Fail!
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 – 20 mm Linear Stepper Motor by Nippon Pulse are available from Electromate!
Motion Control – 20 mm Linear Stepper Motor!
Vaughan, Ontario, Canada — Motion Control — Nippon Pulse is excited to introduce its smallest linear stepper motor yet, the PFL20 Linearstep. The PFL20 is a highly efficient, high thrust tin-can linear actuator with a 20mm diameter and a bipolar winding.
The motion control PFL20 is RoHS-compliant, has a 30/60mm effective stroke, and can reach 6 N of force at 200 pps. With 24 steps per revolution, the lead screw has a 1.2mm thread pitch; the PFL20 also reaches 5V rated voltage, resistance of 33 Ohms/phase and inductance of 12mH/phase. The datasheet with additional specifications can be found here.

XYZ-Theta – Motion Control – CERAMICSPEED Radial Hybrid Bearings Prevents Arcing!
XYZ-Theta – Hybrid Radial Bearings
E. Longmeadow, MA – — Motion Control – CeramicSpeed Insulated ball bearings are custom made for electrical motors and your guarantee against damage caused by stray currents.
The ceramic balls used for this product series are non-conductive and have an insulating ability of 15 kV per mm – higher than that of atmospheric air.
Bearings from competing manufacturers with an insulating coating typically have an insulating ability of up to 1 kV; provided that the coating is not damaged – for example when the bearing is mounted. In practice this protection isn’t always sufficient, meaning that these bearings are also vulnerable to damage by stray currents.
In addition to being protected from the passage of electrical currents, the operating temperature is 10-20 °C lower, and the resulting is a bearing life typically 4-8 times longer than traditional steel bearings.
