The patented Z-Lock is the first ever tapered
bore locking collar system. Just tighten the cap
screws properly and the specialized tapered bore
collar provides extreme holding power on theshaft without causing anydamage. This is a true 360
degree locking
mechanism.
Disassembly is easily
accomplished withtwo threaded holes inthe collar for
standard withdrawal
dismounting.

The triple-lip seal maintains positive contact
with a special sealing ring at virtually anyof shaft mis-alignment. Our new patented
sealing design protects
the bearing against avariety of wet anddry contaminants
and dramatically
improves bearing
life. The ability toaccommodate
shaft expansion is
also available.
Positive seal contact ismaintained during
mis-alignment at any angle.

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 installedmuch faster and easier than adaptor sleeve locks. The installation of Z Lock bearings should be able tobe completed in less than ten minutes and saves cost in both time and manpower.
