⚙️Structure and Material Characteristics:
Composite Structure: Composed of an embedded ball bearing with an extended inner ring and a cast iron square flange seat. The inner ring is equipped with locking screws to achieve a rigid connection between the shaft and the bearing, and can be fixed to the side wall or frame of the equipment through 4 bolt holes;
Core Materials: The bearing body is made of bearing steel (ensuring wear resistance and bearing strength), and the bearing seat is made of cast iron (balancing rigidity and cost advantages);
Sealing Protection: Contact seals are provided on both sides of the bearing, forming a dual protection structure, which can effectively prevent contaminants from invading; The unit can be optionally equipped with end covers to further enhance the sealing level, suitable for complex environments such as high dust and humidity;
Lubrication Design: Pre-filled with lubricating grease, the bearing seat has its own re-lubrication holes and oil nozzles, supporting regular lubrication replenishment to extend the service life.

Installation is convenient: Square flange seat + 4-hole fixation design enables quick integration into the equipment frame;
Versatility is strong: Compatible with constant or alternating rotation directions, allowing for moderate installation errors;
High cost-effectiveness: Cast iron and bearing steel combination material balances performance and cost, with low maintenance costs;
Good durability: Double sealing + re-lubrication design extends the continuous operation time of the equipment.

| 1. Keep clean | 2. Use with caution | 3. appropriate tool | 4. Hot-loading | 5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
