Two-piece JBS type: Featuring a two-piece structural design, both the housing and the spherical inner ring are made from SUJ2 material, offering high hardness, excellent wear resistance and stable precision. The overall structure is compact and robust, with precise transmission fitment. Suitable for various standard mechanical articulation and oscillating transmission applications, it offers stable and durable operation and is compatible with a wide range of general-purpose machinery.
PTFE-Lined FBS Type: The housing and spherical inner ring are made from high-quality SUJ2 material, combined with PTFE wear-resistant liners. This provides excellent self-lubricating and low-friction properties, ensuring maintenance-free operation, wear resistance and quiet running. It is effectively suited to high-frequency oscillating and light-load precision transmission applications, offering a longer service life and compatibility with various transmission structures in automated equipment.
