The product can be used for radial internal and external sealing, and can even tolerate strong shaft runout.
The Seventomatic seal produces consistent linear forces and is less susceptible to shaft runout than other shaft solutions.
Freudenberg Sealing Technologies has succeeded in developing a new seal that reliably prevents leaks from the grease-lubricated main bearings used in conjunction with these shafts while tolerating strong shaft runout.
The product can be used for radial internal and external sealing and can even tolerate strong shaft runout.
This means they are suitable for measuring vibration, amplitude, oscillation and shaft runout. Some suppliers offer capacitive sensors that measure up to 20kHz (-3dB) bandwidths, making them ideal for high speed measurements on rotating shafts.
The results are more extensive deformation of these machine elements and greater shaft runout, also known as eccentricity.
Shaft runout effects may be usually estimated and mitigated by subtracting the unfiltered vibration signal sampled at slow roll speed from the signal measured at the nominal rotating speed [26].

All three series of PumPac bearing arrangements incorporate combinations of 40 and 15 degree bearing contact angles capable of carrying high thrust loads with the 40 degree bearing (without unloading the opposed 15 degree bearing); industry-preferred machined bronze cages highly wear-resistant for optimum functioning in poor lubrication conditions; "CB" endplay for better hall control and reduced heat generation and operating temperature; ABEC 3 tolerances promoting less impeller shaft runout, smoother operation, and longer seal life; and V-etched OD to enable simplified installation by clearly indicating direction of thrust-carrying capability.
Meco seals are engineered to accommodate 6 mm or more of diametric shaft runout.
Designed for problem applications where traditional packings fail to seal, the seals will accommodate 6 mm and more of diametric shaft runout, significant radial misalignment, shock loads, as well as thermal shaft growth in high-temperature machinery.
Seals are designed to accommodate substantial shaft runout and contain abrasive materials.
