TQN Series Telescopic Linear Guides are a compact, high capacity telescopic guide family suitable for the toughest industrial applications. The TQN Series is constructed with cold drawn steel rails that are hardened to provide long life even in equipment with highly repetitive motion. The TLQ Series is very compact with a square cross-section and is suitable for side or bottom mount arrangements. The large cam roller wheel diameter will tolerate contaminates better than ball based designs. An innovative rail-wheel interface will purge contaminates from the raceways. The rails are treated with the innovative T RACE NOX process to make them corrosion resistant.
