ProTech SG Bearing Isolators
Superior Bearing Protection for Electric Motors Innovative design provides 100% exclusion and dissipates shaft voltages Parker Hannifin’s innovative Pro Tech Self Grounding (SG) design provides the highest level of exclusion against water and dust, per IP66 from the International Electromechanical Commission (IEC), specification 60034-5. The seal provides two types of superior bearing protection on electric motors; it excludes 100% of the contaminants and dissipates electrical shaft voltages caused by variable frequency drives (VFD).
Product Highlights:
- Reduces shaft voltage that causes bearing pitting / fluting damage
- Non-contact sealing design means seal will not wear out
- Carbon brush assembly can be easily replaced in the field via an external set screw port
- Two-piece unitized construction provides single cartridge installation
Features of the ProTech SG
- Reduces shaft voltage that causes bearing pitting / fl uting damage
- Non-contact sealing design means seal will not wear out
- Carbon brush assembly can be easily replaced in the fi eld via an external set screw port
- Two-piece unitized construction provides single cartridge installation
- Proprietary labyrinth design outperforms and outlasts isolators that rely on a single internal O-ring for sealing
- Economical upgrade on NEMA motors that require expensive isolator bearings
- Constructed from proprietary conductive PTFE material with documented test results
- First isolator U.L. tested to IEEE 841, meets or exceeds IP55, IP56, IP66, IP69k and API 610
- Includes fl uoroelastomer O-ring for effective sealing in the most severe applications
- CNC machined, no tooling charges
Application Experience With over 60 years experience in the design and manufacture of sealing solutions, Parker is an industry leader in seal design and the innovation leader when it comes to bearing isolator design. Quality ProTech bearing isolators are manufactured under tight control of the entire process – from raw materials to fi nished product. The highest quality and absolute consistency from lot to lot are assured by:
- Use of only fi rst-grade PTFE resins
- Our sophisticated systems for controlling the critical sintering process
- Specialized CNC production equipment
- QS 9000 registered
ProTech Materials
ProTech’s standard reinforced PTFE construction provides a wide range of operating capabilities including high or low temperatures and extreme chemical environments. The addition of other PTFE fillers extends the capability to special designs and services with enhanced physical properties. For example, we offer a PTFE blend for high-temperature stability in large diameter seals, and we also have a new electrically conductive PTFE used in the ProTech SG design.
Best Solution for Electric Motor Shaft Voltage
The ProTech SG’s unique design and superior performance make it an excellent solution for the electric motor market. The seal adds value by decreasing downtime common with bearing pitting / fluting damage, and prevents bearing damage common with contamination intrusion. Both of these design features are incorporated into one bearing isolator.
