Small clearance bearings are a type of rolling bearing characterized by small internal clearance (i.e. the gap between bearing rings), which achieves lower operating torque and axial stiffness through precision manufacturing processes. The following are its core characteristics: structural characteristics Small clearance bearings usually adopt a four point contact design, which evenly distributes the load through four rolling elements to enhance the load-bearing capacity. This structure can reduce friction and wear during high-speed rotation, making it suitable for high-precision equipment. advantage Low torque: Precision manufacturing processes reduce rotational resistance and improve transmission efficiency. High precision: The contact area between the rolling element and the raceway is large, resulting in higher positioning accuracy, making it suitable for precision instruments. High stiffness: The smaller clearance design enhances axial and radial stiffness, improving deformation resistance. Applicable scenarios Widely used in aerospace, automotive industry, machine tool equipment, wind power generation and other fields, especially outstanding in high-speed and high-precision scenarios.
