What are bearings
The main types include:
Ball Bearings: These use small, spherical balls to distribute the load and reduce friction. They are common in a wide range of applications due to their versatility.
Needle Bearings: Similar to roller bearings, needle bearings use long, thin cylindrical rollers. They are designed for applications with limited space and high radial load requirements.
Roller Bearings: Instead of balls, roller bearings use cylindrical rollers to support and distribute loads. They are suitable for heavier radial loads and high-speed applications.
Tapered Roller Bearings: These bearings have tapered rollers and are designed to handle both radial and axial loads. They are often used in applications where heavy axial and radial loads are present.
Thrust Bearings: These bearings are specifically designed to handle axial (thrust) loads and allow components to move parallel to the axis of rotation.
Plain Bearings (Bushings): Plain bearings do not have rolling elements. Instead, they consist of sliding surfaces that allow relative motion between two parts. They are often used in applications with oscillating or sliding movements.
Linear Bearings: Designed for linear motion, these bearings allow movement along a straight path rather than rotation. They are commonly used in linear motion systems.
Spherical Roller Bearings: These bearings have barrel-shaped rollers and can accommodate misalignment. They are commonly used in applications with heavy radial loads and moderate axial loads.
DFL Group is based on Hebei DFL Minmet Refractories Corp. Includes Hebei DFL Minmet Refractories Corp., Hong Kong CODO company, NSAR IND LLC in U.S.A., NSAR bearing manufacturing factory and a number of NSAR brand designated manufacturers. Our brands include NSAR, 3D, OWO, CBQ, and NASA .
NSAR bearings management team of managers, engineers, and technical staff have 15 – 25 years experience.
We supply customers with bearings not only produced in our own factory, but also produced in professional bearings plants designated by NSAR brand to meet customers’ different requirements, such as deep groove ball bearings,pillow block ball bearings,we have designated a factory in northern China, which has perfect testing equipment and can develop products to customer needs very rapidly. Miniature bearings are arranged in the factory in southern China, which has enjoyed a good reputation long term in producing miniature bearings.
