Selection chart below is used for the determination of the maximum allowable frequencies dependent on the rubber suspension unit size (RSS 11, 15, 18, etc.) and the oscillation angle. The higher the frequency, the lower the oscillation angle and the lower the frequency, the higher the oscillation angle as shown in the Allowable Element Frequencies below.
Example: A rubber suspension unit RSS 45 can be rotated from the neutral position of 0˚ to an oscillation angle of +/-7˚ with a maximum frequency of 300 RPM. Contact Lovejoy for applications of “pre-tensioned” elements working, i.e. under 15˚ of pre-tension and describing oscillation angles of +/-5˚ at 300 RPM.
