RunRight® tensioner devices offer a full range of belt and chain tensioning options. They are manufactured with the standard Tensys™ 10 rubber inserts and can be used for applications operating within a -40° to 180°F (-40° to 80°C) temperature range.
RunRight RT N tensioners are manufactured with galvanized powder metal parts and are designed for outdoor or oily applications. The Tensys 20 neoprene inserts are oil resistant and can be used for applications operating within a -22° to 195°F (-30° to 90°C) temperature range.
RunRight RT H tensioners enable a reduction of tensioning force of up to 40% when compared to the RT and RT N tensioners. The Tensys 40 heat resistant rubber inserts are ideal for applications operating within a 180° to 250°F (80° to 120°C) temperature range.
RunRight RT R tensioners are for use on internal combustion engines and compressors. They are manufactured with powder metal or cast iron housings, fully welded steel arms and inner square, come with the standard Tensys 10 rubber inserts and can be used for applications operating within a -40° to 180°F (-40° to 80°C) temperature range.
The housings are manufactured from powder metal, anything larger is manufactured out of cast iron. All arms and inner squares are cast iron. All of the tensioners include a zinc plated mounting screw and locking washer.
