Bearings are mainly used in fitness equipment to reduce friction between moving parts, improve smoothness and durability. For example, the running belt roller of a treadmill requires high-speed bearing support, the flywheel and pedal shaft of a spinning bike rely on silent bearings to ensure smooth rotation, the pulley group and barbell slide rail of a strength trainer achieve low resistance movement through bearings, and the joint parts of elliptical and rowing machines use sealed dust-proof bearings to adapt to frequent use. These applications usually use deep groove ball bearings or self-lubricating bearings to meet the needs of load resistance, rust prevention, and long-term maintenance free.

Ceramic bearings are widely used in wet and corrosive environments such as mixers and filling equipment in food machinery due to their oil-free self-lubricating, corrosion-resistant, non-magnetic insulation, and high hygiene level characteristics. They prevent oil contamination of food and are also used in medical machinery such as surgical tools, dental phones, and imaging equipment that require high-temperature sterilization or demagnetization to ensure sterile operation and precise equipment operation. They are an ideal choice for strict hygiene and high reliability requirements.
