Heavy Duty Machined Race Needle Bearings Without Inner Ring, Open Type, Inch Size
Heavy Duty Cage Needle Bearings are a type of roller bearings that use a cage or retainer to separate and guide the needle rollers. These bearings are designed to handle high radial loads with a compact and lightweight construction.
The needle rollers in these bearings are much thinner in diameter compared to the outer diameter of the bearings. This design allows for a higher surface area contact between the rollers and the raceway, enabling them to support heavy loads while maintaining a small footprint.
The cage or retainer in Heavy Duty Cage Needle Bearings serves several important functions. It maintains the proper spacing between the needle rollers, ensuring even load distribution and reducing friction between the rollers. The cage also acts as a guide, preventing the rollers from skewing or contacting each other excessively.
These bearings are commonly used in various applications across different industries. They are particularly suitable for applications where space is limited, and high load-carrying capacity is required. Some typical applications include automotive transmissions, power tools, printing machinery, textile machinery, and agricultural equipment.
