Innovative solutions for your Power Tools

Freudenberg Sealing Technologies has been involved in the power tools market for decades and understands what really drives the industry. The demand for ever-increasing tool power, combined with lower weight and size, increased lifetime and lower costs along a globalized supply chain, poses major challenges to the entire industry. This is where the industry’s innovation partner of choice, Freudenberg Sealing Technologies, comes in. It helps its customers to gain a competitive edge with its customized, industry-leading special solutions for all key power tools applications.

We look forward to offering our state-of-the-art solutions for just about every power tool application to you as well – from seals and components for electrically driven hammer drills, gasoline-powered chainsaws, pneumatic nail guns, high-pressure cleaners to mowers, to name only a few. Test us, we won’t disappoint you!

Increased durability

FST Radialwellendichtringe Rotary Shaft Seals

Freudenberg’s material and design expertise helps to substantially increase power tools’ durability even at increasing speeds and higher temperatures thereby catering to one of the main needs of our customers. That means manufacturers can expect longer life spans from a Freudenberg Sealing Technologies seal – whether it’s a parametric seal for an electrical or pneumatic tool or an oil seal for a gasoline-fueled device. Our product range includes high wear- and heat-resistant PAH-compliant compounds for electric drills, hammers, grinders, nail guns, circular saws and screw drivers. And best of all: In most cases, our seals and components deliver these increased life spans at a lower cost to add to our customers’ competitiveness in the global market.  

Downsizing is another challenge in the power tools industry that has been addressed by Freudenberg Sealing Technologies: We have developed smaller and lighter customized seals for the segment – more than a small help as the size and weight of tools declines. We are also integrating more and more functions into our seals and components to help reducing the part count in our customers’ systems. For example, we provide components that combine classical sealing functionality with an integrated vibration control function to improve tools’ ergonomics while limiting the part count.

In addition, we continue to develop sealing solutions that withstand today’s higher speeds of mechanical motion. This allows our customers to realize increased tool power and thereby realize savings for the end users by reducing processing times and limiting rework needs.

FST Applications

Electric Power Tools

The most common types of power tools use electric motors to help simplify the work of craftsmen.

The most common types of power tools use electric motors to help simplify the work of craftsmen. The tools have to fulfill a whole set of design requirements (e.g., regarding weight limits, ergonomic demands, corporate style, etc.), but also be technically faultless (e.g., with regards to high power needs, high safety /security demands and long service life) and at the same time meet reasonable price points.

Electric power tools are quieter, cleaner and environmentally friendlier than most other power tools. Our seals and components for applications like drill hammers, grinders, nail guns, circular-saws and screwdrivers are made of highly wear- and-tear-resistant materials and PAH-compliant compounds to meet the specific needs in these applications.

Products we offer for electrical power tools applications are custom-molded parts (made of rubber or polyurethane), Simmerrings®, O-rings, boots and bellows (rubber or polyurethane), vibration control elements, lip seals and wipers.

FST Applications

Gas-powered Tools

Similar to electric power tools with regard to their fields of usage, but driven by gasoline.

Similar to electric power tools with regard to their fields of usage, but driven by gasoline. These tools help end users to get the job done faster because they are generally more powerful. In turn, they come at a mark-up compared to other power tools.

The professional target group and the high price point are linked to users’ and manufacturers’ expectation of very long durability and the extremely high power of these tools. That’s why we offer our customers sealing components tailored to the needs of gasoline- powered tools like chain-saws, trimmers, blowers and hedge-trimmers made of materials with a long service life, decreased friction and maintenance-free characteristics. Our product range for gas-powered tools includes vibration control elements, customized Simmerrings® and O-rings, and custom-molded parts.

Mowers and Cleaning Tools

Mowers help home owners and professionals alike to keep their lawns in shape.

Mowers help home owners and professionals alike to keep their lawns in shape. Depending on their usage, they may be pushed by the operator or allow users to ride them. They must be easy to use and well equipped to meet the demands of tools made for outdoor usage.

Cleaning tools, e.g. high pressure cleaners, are used just about anywhere - in the house, garden or workshop - where you can find shavings, sand, leaves or any other kind of dirt. Just as for mowers, ease of use and suitability for the outdoor environment are key demands on these tools.

For home or residential use, mowers and cleaners are mostly smaller devices, where price, weight and ease of use are key. For industrial and (semi-)professional settings, their size will typically increase. Here, power and durability play a more decisive role. We at Freudenberg Sealing Technologies understand these needs and offer specific solutions for all these applications, e.g. Simmerrings®, O-rings made of rubber or polyurethane, lip seals, wipers, custom-molded parts, vibration control elements, diaphragms, boots and bellows. Ask us for your individual solution.

Pneumatic Power Tools

Pneumatic tools, also called "air" or "compressed power" tools, employ an air compressor to operate.

Pneumatic tools, also called "air" or "compressed power" tools, employ an air compressor to operate. The air compressor is used to pressurize gas that is sent through a hose to operate the tool attached to the end of the hose. Freudenberg Sealing Technologies’ sealing solutions, which ensure both long tool life and compliance to PAH, are specifically designed for use in all pneumatic power tools, e.g. nail guns and wheel guns.

We are your one-stop professional partner for all your sealing needs, including O-rings, pneumatic components, PU or silicon molded parts, vibration control elements and 2K parts.
