The Brief Description of Needle Roller Bearings:
Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter. In spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.
Needle roller bearing has a closed end and is suitable for shaft end applications with high dynamic loads. It has a smaller cross-section than a machined needle roller bearing for use in restricted mounting spaces. The steel cage provides guidance and even spacing of the rollers for minimum vibration and noise when operated at high speeds. The needle rollers are made of through-hardened, high-carbon chromium steel for durability and heat tolerance.
Precautions for Proper Handling of Bearings:
1.Keep bearings and surrounding area clean
Dust and dirt, even if invisible to the naked eye ,have harmful effects on bearings.It is necessary to prevent the entry of dust and dirt by keeping the bearings and their environment as clean as possible.
2.Careful Handling
Heavy shocks during handling may cause bearings to be scratched or otherwise damaged possibly resulting in their failure. Excessively strong impacts may cause brineling,breaking,or cracking.
3.Use proper tools
Always use the proper equipment when handling bearings and avoid general purpose tools.
4.Prevent Corrosion
Since perspiration on the hands and various other contaminants may cause corrosion , keep the hands clean when handling bearings. Wear gloves if possible. Pay attention to rust of bearing caused by corrosive gasses.

High precision BK series open needle roller bearing:
Roller bearings use rolling elements to maintain a separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. Roller bearings can be open on both ends (a shaft can pass through) or open on one end and closed on the other. An open end can be sealed or shielded to protect the bearing from solid contaminants and moisture that could reduce its lifespan. If an end is sealed, the sealing component is an elastomer lip that contacts the shaft. If it is shielded, the shielding is a non-contact lip, usually made of metal. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers etc.
