Contamination is the single biggest problem that bearings face in applications such as aggregate, mining, foresty, pulp and paper and steel mills. Split plummer block units have single lip rubber seals that contact and wear on the shafting. FYH’s original triple lip seals contact on the inner ring and can handle ±2 degrees of shaft misalignment.  This seal design is a distinct advantage over plummer block seals that cannot allow for this amount of misalignment. Adapter sleeves used in a split plummer block require time and skill to install correctly. If the adapter sleeve is incorrectly installed it can be too tight or too loose. FYH's true concentric Z Lock can be installed much faster and easier than adapter sleeve locks. The installation of Z Lock bearings should be able to be completed in less than ten minutes and saves money in both time and manpower.
