Self-lubricating rod end joint bearings are widely used in mechanical systems where low friction and maintenance-free operation are essential. These bearings are designed to handle both radial and axial loads, making them ideal for applications such as industrial machinery, automotive components, and hydraulic systems. 1) **SI...C Type**: This bearing is an assembly of CE...C type bearings with a threaded rod end. The rod end is internally threaded, made from carbon structural steel. It can withstand constant loads in one direction and is capable of handling axial loads in either direction, up to 0.2 times the radial load. 2) **SA...C Type**: Similar to the SI...C type, this model also consists of CE...C bearings but features an externally threaded rod end. It is also constructed from carbon structural steel and is suitable for unidirectional loading, with axial loads not exceeding 0.2 times the radial load. 3) **SI...CS-2Z**: This version includes GE...CS-2Z bearings and an internally threaded rod end. Made from carbon structural steel, it supports radial loads and axial loads in either direction, with the axial load not exceeding 0.2 times the radial load. 4) **SA...CS-2Z**: A similar configuration to SI...CS-2Z, but with an externally threaded rod end. It also allows for radial and axial loads, with the axial load not exceeding 0.2 times the radial load. 5) **SIB...C**: Features an internally threaded rod end made from carbon structural steel. The outer sliding surface is composed of sintered bronze composite material, while the inner ring is hardened bearing steel. The outer surface is coated with hard chrome, allowing it to handle constant radial loads. 6) **SAB...C**: This model has an externally threaded rod end made from carbon structural steel. The sliding surface is also made of sintered bronze composite material, with a hardened bearing steel inner ring and hard chrome plating. It is suitable for constant radial loads. 7) **SIB...F**: Designed with an internally threaded rod end, this bearing uses glass fiber reinforced plastic with PTFE as an additive for the sliding surface. The inner ring is hardened bearing steel, and the sliding surface is hard chrome plated. It can handle radial loads in a fixed direction. 8) **SAB...F**: Similar to SIB...F, but with an externally threaded rod end. The sliding surface is made of glass fiber reinforced plastic with PTFE, and the inner ring is hardened bearing steel. The sliding surface is also hard chrome plated, enabling it to support radial loads in a constant direction. 9) **SQ...L Type**: This bearing is made from a special self-lubricating alloy material. It can handle radial loads and small axial loads in either direction, making it ideal for applications requiring long-term reliability without lubrication. Self-lubricating rod end joint bearings offer a reliable and efficient solution for various mechanical systems. Their design ensures minimal maintenance, reduced wear, and extended service life, which makes them a popular choice across multiple industries.
