LM76 has introduced the SPEED DEMON EL300 rail/roller bearing wheel system, their latest edition to the SPEED DEMON linear bearing family. Featuring travel lengths of 400 mm to 3000 mm, the 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 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° angle to ensure 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 4 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) – 2800 N static and 1400 N dynamic, and Horizontal (side)- 2600 N static 1300 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 4 threaded mounting holes and 5 “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.
