A Solution for the Toughest Applications
ProTech Bearing Isolators offer superior protection even in harsh operating environments such a food and paper processing and in gearbox applications. Advanced proprietary PTFE compounds mean ProTech is well suited for caustic environments such as citric acids found in juice processing and strong sulfides in pulp and paper processing. ProTech 360 is a hybrid design that incorporates an outboard labyrinth for contaminant exclusion and PTFE lip technology for positive oil retention, even in vertical down applications, making it suitable for demanding gearbox applications.

Protect Your Bearings with ProTech™
Protecting your bearings not only helps extend the life of your machine, but it also reduces maintenance costs and increases reliability and efficiency. Parker’s ProTech Bearing Isolators are designed to meet the challenge in protecting your bearings from contaminants, even in the harshest environments.
In this 30-minute webinar, our experts explore the basics of labyrinth seal theory, examine the advantages of using bearing isolators in industrial applications and analyze real-world examples of how ProTech bearing isolators have solved complex sealing challenges in a variety of applications.

Protech Bearing Isolator Seals
ProTech Bearing Isolators are unitized two-piece, dynamic seals. The permanently assembled rotor and stator utilize labyrinth technology for complete lubricant retention and contaminant exclusion, thereby extending bearing life -- with zero shaft wear.
Bearing isolators are an upgrade from standard lip seals, however when one considers the total cost of the sealing system over the total life span, it is well worth it for key equipment such as pumps, motors, gear boxes, and split pillow blocks.
A Wide Range of Capabilities
- Size Range: Up to 60"
- Pressure: 0 psi (5 psi for select profiles)
- Speed:
- PTFE designs to 5,000 fpm
- Metallic designs to 7,000 fpm
- Easy-to-install press-fit on shaft and bore
- Labyrinth seal design
- Zero wear
- Zero torque consumption
- Superior water and dust exclusion
- Proprietary PTFE compounds including FDA compliant materials
- UL certified & IEEE IP-rated designs
Standard Profiles Available
- Available with or without flange to provide labyrinth sealing in restricted widths
- Single and multiple expulsion (drain) ports when directional installation is a concern
- Exceed IEEE-841 to provide premium bearing protection on severe-duty electric motors
- Split pillow block design meets OEM specifications
- Custom designs are available for higher speeds, axial movement and high misalignment (STBM) conditions.
Save Money with ProTech
Bearing isolators are an upgrade from standard lip seals, however when one considers the total cost of the sealing system over the total life span, it is well worth it for key equipment such as pumps, motors, gear boxes, and split pillow blocks.
The cost of downtime in today’s manufacturing environment has been the primary driver behind companies’ decisions to convert from standard lip seals to bearing isolator-type seals. Standard lip seals have a typical life of 3,000 to 5,000 hours. With true non-contact ProTech designs there is nothing to wear out; thereby extending mean time between failure (MTBF). With a bearing isolator solution, the seal is no longer the limiting factor for the bearings reaching the basic life rating stated by bearing manufacturers (L10 rating).
Cost savings are realized by
- Less unplanned downtime
- Lower maintenance expenses with fewer rebuilds
- Lower torque consumption which results in lower energy usage
In some cases, the energy savings alone offsets upgrade costs.
