ENGINEERED SEALING SOLUTIONS, LLC
"We are committed to turning your costs into profits"
The unique ProTech bearing isolator was developed to overcome the design flaws of existing bearing isolators on the market. Improvements included using a PTFE material to provide superior chemical resistance and eliminate bearing killing metallic dusting. A unitized two-piece construction was incorporated to make installation simple. For unmatched two-way sealing, zero lubricant leakage and total exclusion of contaminants, a sophisticated internal labyrinth was designed. This allows ProTech to exclude contaminates without using an internal o-ring as the primary sealing component. The ability to handle higher amounts of shaft run out was also a concern. Since internal o-rings were avoided, as much as .020” misalignment can be accommodated without damaging the seal.
All ProTech bearing isolators feature the following:
• PTFE materials for chemical resistance and low torque consumption
• Fewer working components
• Significantly lower cost
• Easier to install than traditional bearing isolators
• Accommodates greater shaft misalignment and eccentricity
• Self-aligning
• Requires no lubrication
• Non-contact design for no wear and no heat generation
• Total exclusion of dust, water, and other contaminants
• Zero lubricant leakage
