Contamination is the single biggest problem that bearings face in applications such as aggregate, mining, forestry, 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, plummer block seals are not designed for this amount of misalignment.
Adapter sleeves used in a split plummer blocks require time and skill to install correctly, incorrect installation can allow them to be too tight or too loose. FYH’s true concentric Z Lock can be installed much faster and easier than adaptor sleeve locks. The installation of Z Lock bearings should be able to be completed in less than ten minutes and saves cost in both time and manpower.
