New rail/roller bearing wheel system for high speed, low friction linear motion
LM76’s new SPEED DEMON EL300 rail/roller bearing wheel system is the latest edition to the SPEED DEMON linear bearing family. It features travel lengths of 400 to 3,000 mm, a wide 90 mm base and 49 mm centerline to centerline of the parallel rails of the base, and 100 mm centerline to centerline spacing of […]
FDA-compliant off-the-shelf linear motion components for urgently needed medical products
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 […]
One-piece ETX linear bearing/pillow blocks suitable for use in radioactive environments
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. Custom designed for use in a nuclear power plant these […]
New bearing from igus assists in quick, easy liner replacement
igus has introduced a new bearing, drylin W Exchange, for its drylin W linear system in which the liner can be replaced directly on the rail without dismantling the system. By using a practical assembly tool, users can push the old liner out of the housing, clip the new one on to the shaft and […]
“New Design” pillow and flange blocks from LM76 allow for easy bearing lubrication
“New Design” pillow blocks and flange blocks from LM76 feature a lubrication fitting and an alignment set screw in the pillow blocks and flange blocks. 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 […]

Pegasus Series 1 corrosion-resistant linear bearings from LM76
LM76 has developed the most corrosion resistant linear bearing available. The 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. In space, deep under the sea, or in the harshest environments when there can be […]
Moment of inertia: area or mass?
Moment of inertia is an important parameter when sizing and selecting a linear system. But it’s critical to know which type of inertia—planar moment of inertia or mass moment of inertia—is given and how it affects the performance of the system. Planar moment of inertia Planar moment of inertia (also referred to as second moment of […]
A glossary of linear guide terminology
The term linear guide covers several categories of products, from plain bearings to ball bushings and recirculating roller bearings. To compound the potential for confusion, many terms are used interchangeably, or are so generic (take linear guide for example) that they could refer to any one of several different products. And this doesn’t apply to just […]
