SF-2S Lead-free Lubricated Bearing for Printing and Dyeing Machines

The SF-2S oil-free bearing, as an upgrade to the SF-2 series, stands out with its unique design concept and excellent performance. It features a solid steel back as the base, with a middle layer cleverly sintered with spherical tin bronze powder, and a surface meticulously coated with a high-performance special polymer material. This bearing exhibits several significant advantages:
· Adaptive lubrication mechanism: Even under harsh conditions of room temperature or low oil environments, the SF-2S can easily cope, demonstrating extremely low friction coefficients and outstanding wear resistance.
· Extraordinary load-bearing and wear resistance: With a maximum static load capacity of up to 140N/mm² and an impressive dynamic load capacity of 70N/mm², it effortlessly meets the demands of various complex working conditions. Additionally, its excellent wear resistance ensures a long service life.
· Long-term maintenance-free characteristics: Under boundary lubrication conditions, the SF-2S can operate stably for extended periods without the need for additional oiling, significantly reducing maintenance costs and enhancing equipment efficiency.
· Stable dimensional characteristics: Its non-absorbent properties for both water and oil ensure long-term dimensional stability of the bearing, further extending its service life.
· Convenient processing performance: During the press-fitting process, the bearing can be flexibly reprocessed to achieve more precise tolerance matching, satisfying various precision requirements.
· Environmentally friendly material: The surface material is completely lead-free, fully complying with current environmental standards, and providing an ideal solution for applications in lead-free fields.
The SF-2S oil-free lubricating bearing is widely used in various mechanical equipment that require self-lubricating properties. For example, in applications involving swinging motions, susceptibility to wear, and corrosion, such as winches, bulldozers, printing and dyeing machines, coal mining machines, as well as cranes and overhead cranes for high-altitude operations, the SF-2S bearing plays a crucial role. Its oil-free lubricating characteristic allows these devices to maintain efficient and stable operation while reducing maintenance costs. Furthermore, the SF-2S bearing is often given priority consideration in situations where high load-bearing capacity and low friction coefficients are required.
