Instructions for purchasing pulley wheel

Pulleys are often used in sliding doors in spaces such as balconies, kitchens, and restaurants, and the smooth sliding of sliding doors is largely achieved through the design and manufacturing of high-quality pulley systems. The bearings used for manufacturing pulleys must be multi-layer composite structure bearings, with the outermost layer being high-strength wear-resistant nylon liner, and the nylon surface must be very smooth without any ribbed protrusions; The inner ball bracket is also a high-strength nylon structure, reducing friction and enhancing the lubrication performance of the bearing; The load-bearing layers are all steel structures, and most of the pulleys in this design are ultra silent, with a service life of about 15-20 years.

Pulleys are important hardware components. Currently, there are three types of pulleys available on the market: plastic pulleys, metal pulleys, and fiberglass pulleys. Plastic pulleys have a hard texture, but they are prone to cracking. Over time, they become astringent and hard, resulting in poor push-pull feel; Metal pulleys have high strength and hardness, but are prone to noise when in contact with the track; The fiberglass pulley has good toughness, wear resistance, smooth sliding, and durability.
