Ten Facts You Never Knew About Spindle Bearings.
Spindle Bearings cylindrical roller bearings are characterized by:
- High speed capability
- High radial load carrying capacity
- High rigidity
- Low friction
- Low cross-sectional height
These bearings are therefore particularly well suited for machine tool spindles where the bearing arrangement must accommodate heavy radial loads and high speeds, while providing a high degree of stiffness.
Spindle Bearings single row cylindrical roller bearings have a higher speed capability than double row bearings while double row bearings are more suitable for heavier loads.

How are ball bearings made
Bearing balls are components of ball bearings that achieve a smooth, frictionless rotational motion. They are usually made of steel, but can also be made of other materials, such as silicon nitride ceramics, plastics, and even glass.
Steel bearing balls are easily the most common ball material, with tens of millions produced each year. They are nearly perfectly round and mirror-polished to provide precise rotational motion in machines, power tools, motors, power transmission, and hundreds of other applications.
Have you ever wondered how they are made? The answer is a multi-step process that transforms a block of unhardened steel into a hardened, ground and polished ball.
How are ball bearings manufactured?
The outer ring enters the grinder which shapes its outer surface to a precise roundness and diameter lubricants keep the ring from overheating.
