A Solution for the Toughest Applications
ProTech™ Bearing Isolators offer superior protection even in harsh operating environments such a food & paper processing & in gearbox applications.
Parker ProTech Bearing Isolator Flyer
Unitized Two-Piece, Dynamic Seals
Parker developed the unique ProTechTM design to provide unmatched two-way sealing for zero lubricant leakage & total exclusion of contaminants. This is accomplished by using non-contact labyrinth seal technology. ProTechTM features the most effective labyrinth design for both dirt exclusion & oil retention & is far superior to isolators that rely on internal o-rings or other internal seals.
Unmatched Corrosion Resistance
- Advanced proprietary PTFE compounds mean ProTech™ is well suited for caustic environments such as citric acids found in juice processing & strong sulfides in pulp & paper processing.
- ProTech’s superior chemical resistance allows for the standardization of a single material within a plant, eliminating the need to stock duplicate sizes in expensive stainless steel, Hastelloy® or other exotic materials. PTFE iscompatible with over 160 chemicals.
Ultimate Gearbox Performance
- ProTech™ 360 is a hybrid design that incorporates an outboard labyrinth for contaminant exclusion & PTFE lip for positive oil retention, even in vertical down applications, making it suitable for demanding gearbox applications
- Upgrading gearboxes that drive cooling tower fans with the ProTech™ 360 design on the input shaft & the ProTech™ LX design (LW without drain port) for the vertical up location is becoming the industry standard for preventing failure due to moisture intrusion.
Solutions For Food Processing Applications
ProTech™’s WD is an economical profile for high volume, disposable equipment such as wash down grade motors & drives. It also greatly reduces maintenance costs & down time in poultry processing applications such as picker hubs. Anti-microbial & FDA materials are readily available.
Prefer A Metallic Isolator?
Parker’s Millennium® bearing isolator is based on patented labyrinth seal technology & robust non-contact isolator needs no internal o-ring seal to exclude heavy water spray. No internal seal means zero wear & longer life. Severe oil splash retention grooves, unitized cartridge design & tool-free installation are also standard features.
