Parker’s ProTech™ bearing isolator seals feature a unique labyrinth design that provides unmatched two-way sealing for both zero lubricant leakage and total exclusion of contaminants.

Its advanced proprietary PTFE compounds make ProTech well-suited for caustic, high-speed, and high-temperature environments. These highly chemical-resistant seals perform well in high-speed and high-temperature environments.  For example, ProTech is well suited for caustic environments such as citric acids in juice processing and strong sulfides in pulp and paper processing.

This bearing isolator is a unitized, two-piece non-contact design that offers extended bearing life.    It is this characteristic labyrinth technology that provides contaminant exclusion instead of an internal O-ring protection. 

ProTech™ bearing isolator seals offer an answer for applications where improving the mean time between failure (MTBF) is critical. The ProTech family relies on true non-contact labyrinth seal technology to provide 100% exclusion of contaminants and 100% retention of bearing lubrication for the life of the bearing. 

The superior quality and high performance of ProTec™ seals make it the ultimate in bearing protection.  Parker, the innovation leader in bearing isolator technology, has designed this unique sealing component to deliver maximum protection for a multitude of applications.

Web Seal can provide ProTech seals in many standard and custom designs, with support to ensure that the proper isolator for your equipment and application is recommended. Expedited delivery is available.
