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 the radial roller bearings (wheels) of the carriage, which provide high torsional stability and high torque load stability.

Attached to the rigid, heavy duty extruded base are parallel 12 mm h2 steel shafts hardened to RC62+2. The shafts are secured to the base every 100 mm at a 45-degree angle to insure parallelism. The base can be easily integrated directly into the user’s system using the predrilled mounting holes or LM76’s Heavy-Duty full length mounting plates for increased stability.

The carriage of the SPEED DEMON EL300 features four sealed, low friction,dual angular contact roller bearings. On one side of the carriage the roller bearings have eccentric bushings for adjusting preload. The maximum loads are: vertical (down) – 2,800 N static and 1,400 N dynamic, and horizontal (side)- 2,600 N static 1,300 N dynamic. The maximum moment loads are: roll – 125 N-m static and 62 N-m dynamic, pitch – 165 N-m static 80 N-m dynamic, and yaw – 82 N-m static 40 N-m dynamic.  Additionally, the carriage has four threaded mounting holes and five “T” slots running the length of the carriage to facilitate the mounting of tooling or fixtures. The height of the carriage and base assembly is just 54 mm, and both are clear anodized.

Other members of the SPEED DEMON linear bearing family include the SG, and OSG models which are also stable, high-speed solutions for challenging linear motion applications.
