Micro Seals Revolutionize Performance through Freudenberg

Micro Simmerring®: Precision Sealing for Miniaturized Shafts

As industries move toward miniaturization, the demand for precise sealing solutions is increasing. Freudenberg's Micro Simmerrings® stand out as reliable seals tailored explicitly for small shafts, showcasing customer-specific designs and elastomer materials adept at meeting diverse requirements. These seals offer versatile sealing for rotary shafts, spanning inner diameters from 1 mm to 3 mm. They excel in sealing oil, food-compatible detergents, and aggressive media within a temperature range of 40 to 200°C.

Customers benefit immensely from these Micro Simmerrings® through enhanced durability, extending product lifespan and reducing maintenance costs. Featuring a springless elastomer lip design, these seals minimize friction torque, ensuring efficient performance. Developmental efficiency is a hallmark, progressing from pre-development stages to serial production within nine months, catering swiftly to evolving needs. Notably, their exceptional performance includes a dry running capability and minimal adhesion, even in dry conditions, ensuring unparalleled reliability.

Their resilience to chemicals is commendable, achieved through high-performance elastomers like XP and Simriz.

Their advantages are numerous: boasting functional excellence with a tribological pump effect, embodying a hygienic product design, and delivering impeccable performance without detectable adhesion, be it in wet or dry starts. The seal undergoes strict tests for endurance, and they are easy to use because they do not require any tools to put together.

Rocker Valve Seals

Freudenberg Sealing Technologies' Rocker Valve Seals exemplify meticulous engineering, crafted for precision and reliability in demanding environments. Each seal embodies an elastomer composite part functioning as a static seal with a bead, accompanied by two dynamic seal pads to enhance operational efficiency. The seal comprises a precisely engineered plastic carrier part with bearing bore, guaranteeing optimal performance within rocker valve systems. The rocker valve seals can be produced out of one single tool with different elastomers (e. g. FFKM, FKM, EPDM) suitable for dedicated applications.

Rocker valves, known as critical components within several applications for laboratory and analytics, are pivotal for regulating media and gases. In this precise environment, proper sealing is paramount to prevent any leakage during processing, ensuring optimal function efficiency.

You can rely on our seals to provide exceptional sealing capabilities, ensuring prolonged durability and increased efficiency in your rocker valve systems. Their adaptability extends to 2/3-way valves in microfluidics, medical technologies, and laboratory environments. Anticipate reliable and long-lasting sealing solutions customized to meet the specific demands of these specialized industries.

Brake & Seal Disc

Innovating within dental drill technology, Freudenberg Sealing Technologies presents a remarkable advancement in miniaturization of brake & seal discs. These drills incorporate a specialized seal that serves a dual role: preventing liquid infiltration while also acting as a critical brake to swiftly halt shaft rotation within a second for enhanced safety measures. Operating as air-pressure turbines, these dental tools achieve incredible rotational speeds of up to 350,000 rpm.

Precision is paramount in this specialized development: the demanded lip thickness achieved during manufacturing, measuring a mere few tenths of millimeters, accompanied by a manufacturing tolerance in the hundredth range, serves as a testament to the attained process accuracy.

Brake & Seals discs within dental drills have relevance and application within dental equipment and devices, especially in dental drills used within dental practices and clinics. These drills, operating as air-pressure turbines, rely on this seal to prevent liquid ingress into the drill and to function as a safety brake to swiftly halt shaft rotation.
