TBI's high-quality linear guides deliver precision, durability, and affordability in one single package! Available in a 20 mm size, this sleek, high-quality design incorporates the rail and the block together to provide a convenient, easy-to-use product. Little friction resistance allows for high accuracy and speed, while several preload options are available for increased rigidity and performance. They are offered in standard or custom lengths, and are ideal for dynamic loads up to 25.03 kN and static loads up to 49.6 kN. For rail lengths longer than the full continuous length specification, rails can be butt-jointed to achieve the desired length. All standard blocks come with a bottom seal and double lip end seals.
