B-Bearing

Generally refers to the bearing used in cylinder-related components (such as pistons, crankshafts, etc.), mainly playing the role of supporting and reducing friction, and can adapt to the reciprocating or rotating motion environment in the cylinder. It needs to withstand a certain temperature and pressure, and its structure is designed according to the stress situation. It is commonly used in cylinder components of internal combustion engines, compressors, etc., to ensure smooth movement and extend the service life of components.

Rolling Bearings
Composed of inner rings, outer rings, rolling elements (balls, rollers, or needles), and retainers, rolling bearings are widely used due to their low friction and easy maintenance. Ball bearings (e.g., deep groove ball bearings) are suitable for high-speed, light-to-medium load scenarios, such as electric motors. Roller bearings (e.g., cylindrical roller bearings, tapered roller bearings) excel in heavy-load applications, making them ideal for automotive axles and industrial gearboxes. Needle roller bearings, with slender rolling elements, are compact and used in space-constrained parts like engine connecting rods.
Product1
Plain Bearings
Also known as sliding bearings, they have a simple structure (typically consisting of a bearing shell and a shaft sleeve) and operate through sliding contact. Plain bearings are cost-effective, capable of withstanding extremely heavy loads, and are used in large machinery like steam turbines, marine propeller shafts, and hydraulic cylinders. They require proper lubrication (oil or grease) to reduce friction and prevent seizing.
Product1
Specialized Bearings
Tailored for specific working conditions, these include thrust bearings (supporting axial loads, used in aircraft engines and lathes), linear bearings (enabling linear motion, applied in CNC machine tools and sliding doors), and ceramic bearings (with high-temperature resistance and corrosion resistance, suitable for medical equipment and aerospace devices).
