- Rod Ends: Models include JF, JM, JFG, JMG, JFT, JMT, JFTS, and JMTS. Primarily used in control rod linkage devices for transmitting tensile and compressive loads, these self-aligning bearings offer excellent performance in rotational and oscillating motions. The spherical inner ring is made of heat-treated high-carbon chromium bearing steel, the housing from SM45C or S45C carbon steel, with both maintenance-free (JFT, JMT) and stainless steel (JFTS, JMTS) options available.Rod Ends: Models include JF, JM, JFG, JMG, JFT, JMT, JFTS, and JMTS.

- Spherical Plains: Models include GE, SB, JS, and JET. These are suitable for accommodating heavy radial loads and are ideal for axial arrangements with shaft misalignment, tilting, rotational, or oscillatory motions at relatively slow sliding velocities. Products like GE20FO-2RS~GE80FO-2RS are press-fitted for heavy-duty applications.Spherical Plains: Models include GE, SB, JS, and JET.

- Ball Joints: Models include ZBL and ZBS. These bearings are for linkage control, facilitating rotational and oscillating movements in various industrial machines. They are manufactured by electrically welding stud bolts with high-precision steel balls and include rubber caps for waterproofing, rust prevention, and grease retention.Ball Joints: Models include ZBL and ZBS.
