What makes RunRight Products Superior RunRight rubber suspension units are designed for use in applications requiring a torsional spring feature with angles of operation of +/-30°. When using these units in an application, the torsional force that is applied as well as the radial, axial and/or cardanic forces need to be taken into consideration when sizing a unit. See page 51 for the applicable RunRight units' torque and load characteristics. Md O aMk Spring Characteristic When the RunRight rubber suspension units are pivoted, a nearly linear spring characteristic occurs with a slightly...

The calculation of the natural frequency of a RunRight suspension unit has to be solved by drawing the tangent line at the loading point “A” of the parabolic arc of the load deflection curve. The distance on the axis of the abscissa, i.e. resulting “S”, designates the arithmetical spring deflection in mm which is required for the determination of the natural frequency. Natural Frequency Cold Flow and Deformation Initial deflection When a load is continually applied to an elastic material, such as the Tensys™ units, deformation or cold flow occurs. Cold flow appears during a linear...

RunRight Product Technology Service Life Service life When the rubber suspension units are operating within the specified frequencies, oscillation angles, and recommended surrounding conditions, the unit’s performance and function will be expected to perform for many years. Extremely low or high permanent temperatures will significantly shorten the life expectancy of the rubber suspension units. The Service Life Curve Chart shown to the right shows the life reduction at extreme high and low temperatures using a service life of 1 at the room temperature of 72°F (22˚C). Allowable Element...

Run Righ tby£2mz2f Rubber Compounds Rubber Characteristics The majority of RunRight rubber suspension units are manufactured with Tensys™ 10 natural rubber inserts. The high content of natural rubber in the Tensys 10 offers shape retention, a limited amount of deformation, high mechanical load capabilities and limited hardening of the inserts. Applications requiring high oil resistance, high heat resistance or higher torque capability requires a different elastomeric insert as shown in the chart below. Chemical Resistance Standard RunRight rubber suspension units are manufactured with...

TENSIONER DEVICES Tensioner Technology Install RunRight tensioners on a rigid, flat and clean machine surface using the mounting bolt provided. The frictional contact between the tensioner housing and the machine surface is usually sufficient for proper installation. If the surface of the machine is uneven or highly corroded, a locking pin can be used at the positioning notch for a secure connection to a machine's irregular surface. Tensioning Force The tensioning force of the RunRight tensioner can be continuously adjusted. The maximum installation tensioning torque is 30° from the neutral...

RunRight Tensioners Type RT, RT N, RT H, RT R RunRight RT tensioners offer a full range of belt and chain tensioners. 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...

RunRight Tensioners Type RT F (Front Mount) RunRight RT F tensioners are designed for front mounting applications where access to back side or rear mounting surfaces is not possible. A single threaded hole is required to mount these tensioners. These tensioners include a special mounting screw and spacer bushing. The housings are manufactured from powder metal, cast iron or steel. All arms and inner squares are cast steel or steel weldments. They 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...
