Bearing arrangements for eccentric shafts, e.g. for vibratory sheet pile drivers and vibratory compaction equipment must provide reliable support for high shock loads and radial acceleration in the smallest possible design space. Vibratory rollers and vibrating screens are a particularly wide area of use for eccentric shaft bearings.
High limiting speeds are required. Misaligned bearing positions and shaft deflections put an additional strain on the bearings. Ambient conditions are also often unfavorable.
