Demo: Gearbox Sealing Solutions

Engineering Resilience: Innovative Sealing and Venting Solutions for Industrial Applications
The demo unit shown here was inspired by a recent project in which many of the same sealing and venting products were recommended for use in a functional gearbox.
Components Utilized in this Demo:


Gore® PMF100570 Gearbox Vent
- Improve component reliability: GORE® Protective Vents for Gearboxes (PMF100570) has an integrated membrane that effectively blocks contaminants — like water, dust and dirt — that can degrade the performance of oilcooled traditional and e-motors and other e-drivetrain components as well as gearboxes. The integrated pre-filter protects the membrane from internal oil aerosol that would quickly degrade a standard membrane vent.
- Preserve seal integrity: At the heart of these vents is the breathable GORE Membrane: It equalizes pressures under both normal and extreme operating conditions, to avert stress on seals.


Rogers Bisco HT-800 Silicone Foam
BISCO HT-800 Medium Cellular Silicone is a versatile, medium firmness silicone. HT-800 silicone foam leads the market in sealing and protecting outdoor communication, electronics and lighting enclosures. HT-800 silicone foam’s superb memory and low stress relaxation reduces maintenance costs from gasket failures caused by compression set and softening. Its compact cell structure and unique formulation provide enhanced sealing against penetration from fine particles and wind-driven rain and fire. It also offers shock reduction and vibration isolation in electronic components and transportation vehicles.
Benefits
- Offers consistent performance in all environments
- Excellent memory and low stress relaxation
- Reduces maintenance costs associated with gasket failures due to compression set and softening


3M VHB Gaskets
3M™ 4926 VHB™ Tape – 0.015″ is an acrylic foam tape that provides high-strength bonding and effective gasketing for gearbox covers and housings. Its conformable design ensures a tight seal, even on irregular surfaces.
Features:
- Acrylic foam core for permanent bonding
- Excellent resistance to vibration, moisture, and thermal cycling
- Conforms to uneven surfaces for a secure seal
- Typical uses: gearbox covers, housing assemblies, vibration dampening


Loctite 3321 Light Cure Adhesive
Loctite® 3321 Light Cure Adhesive is a UV/visible light-curing adhesive ideal for high-speed, automated assembly of gearbox components. It delivers strong bonds with clean, precise application.
Features:
- UV/visible light cure for rapid processing
- High shear strength on metals and plastics
- Low migration for accurate dispensing
- Typical uses: shaft collars, housing seams, and gearbox assembly


Freudenberg BAUMSL Rotary Oil Seals
Freudenberg BAUMSL Rotary Shaft Seals are built for high-speed rotary applications, protecting gearbox shafts by keeping lubrication in and contaminants out.
Features:
- Advanced elastomeric sealing lip with metal case
- Compatible with various oils and greases
- Designed for dynamic, high-speed shaft applications
- Typical uses: gearbox output shafts and industrial drive systems
Common Application Requirements
-
Prevent fluid leakage (oil and lubricants).
-
Exclude contaminants (dust, dirt, water, and debris).
-
Withstand pressure fluctuations without seal failure.
-
Handle thermal expansion and temperature extremes.
-
Maintain long-term durability in harsh environments.
-

Rethink Solutions for Bonding Composites and LSE Plastics
3M™ VHB™ Tape provides a flexible bond that allows for thermal expansion up to three times its thickness and is therefore ideal for joining dissimilar materials. It shows excellent dynamic stress performance that can even exceed certain structural bonds. By taking advantage of its ability to adhere to difficult-to-bond substrates, you can use lighter and thinner materials for groundbreaking innovations in form and function, supporting durability, aesthetics and weight reduction.
Recent advances in multi-material tapes and adhesives provide designers and manufacturers new assembly options beyond traditional mechanical and thermal assembly methods.
