SPEED DEMON FAMILY
The SPEED DEMON Family consists
of 3 roller block configurations:

These systems employ round shafting, aluminum bodies and dual, angular contact - sealed - roller bearing wheels. Each has built-in preload adjustability. SPEED DEMONS are capable of speeds up to 10 meters per second. SPEED DEMONS are easy to install, lightweight and inexpensive.
     
SG SPEED DEMON Roller Blocks come with three roller options so you can increase load without
increasing the height or width of your design. Quick, Flexible, Low Noise, Smooth and Proven.
