Ntn High Precision Angular Contact Ball Bearings - Carbon Steel, Silver, Grease Lubrication | Engineered For High-speed Machining, Enhanced Load Capacity, Ultage Performance

NTN offers a wide range of Precision Angular Contact Ball Bearings for use in high speed machining. These product designs are manufactured to address both radial & thrust loads while still maintaining speed requirements needed for metalworking and other machining processes. These designs are normally found in CNC spindles which are critical for maintaining tight tolerances to achieve proper finished goods in manufacturing.

Precision Cylindrical Roller Bearings are essential in spindle designs utilized in the manufacturing marketplace. Both single and double row precision cylindrical roller bearing designs are manufactured with tighter tolerances and clearance options to maintain efficient finished goods. Cylindrical rollers bearings are required where thrust loads and rigidity are present in the machining process.

Precision Taper Roller Bearings are utilized within some CNC machining processes. They are found in small spindle designs that require heavy thrust load capabilities. They also can be found in other machining functions not related to the primary spindle itself. Their precision taper rollers are manufactured with tighter tolerances to maintain proper functionality.

The rigidity of the main spindle of a machine tool is associated with both bearing rigidity and shaft rigidity. Bearing rigidity is typically governed by the elastic deformation between the rolling elements and raceway surface under load. Usually, bearings are preloaded in order to increase the rigidity. Under same loading conditions, a roller bearing has a higher rigidity than a ball bearing of the same size.
