Triple-Sealed Bearings for Ball Bearing Units

The Ultimate Solution for Dustproofing and Waterproofing

Ball Bearing Units

NHK Triple-sealed bearing units are engineered to provide superior dustproofing and waterproofing, significantly enhancing the longevity and reliability of ball bearing units. These bearings are equipped with a secure seal featuring three lips, offering protection against contaminants far superior to standard bearing seals.

Usage and Applications

NHK Triple-sealed bearing units are ideal for environments where machinery is exposed to heavy airborne dust and splashes of foul water. Industries such as steel-making, casting, garbage disposal, waterworks, sewage treatment, car washing, laundry washing, food processing, fish processing, construction, transportation, agriculture, textiles, and dyeing benefit from the enhanced protection these bearings offer.

Industry Applications

In the building materials manufacturing sector, machinery often encounters substantial dust and water exposure. For instance, in cement production plants, brick kilns, and steel mills, the presence of heavy airborne dust and high humidity can adversely affect bearing performance. Switching from standard bearings to triple-sealed bearings can significantly extend bearing life in these challenging conditions.

Material and Design

The construction of triple-sealed bearings involves a galvanized steel plate that enhances corrosion resistance. The optimal design contributes to improved pressure resistance, while the rubber seal extends to the outer circumference of the shielded plate, preventing contamination by dust or foul water. This design ensures excellent dustproofing and waterproofing, protecting the bearing from environmental contaminants.

Experience and Expertise

Manufacturers like NHK bearing units have developed triple-sealed bearings that feature a secure seal with three lips, providing reliable dustproofing and waterproofing superior to standard bearings. This design ensures a longer service life, even when exposed to heavy airborne dust and splashes of foul water.

Authoritativeness

NHK bearing units with triple lip seals are designed to protect bearings in severe conditions involving dust, sand, water, or slurry. The triple lip seal is a one-piece molded nitrile seal with three sealing lips, bonded to a protective outer steel pressing secured in the outer ring. This highly efficient sealing design ensures maximum protection against contaminants.

Trustworthiness

Tests have shown that by switching from standard-type bearings to triple-sealed bearings, the bearing life can be extended significantly. For example, in muddy water resistance tests, triple-sealed bearings have demonstrated a lifespan up to 59 times longer than equivalent standard bearings.
