Boca Bearings
Boca Bearings introduces the new and expanded range of machine tool spindle bearings in both steel and ceramic hybrid configurations. The new line of steel and ceramic hybrid machine tool spindle bearings are designed for today's demanding manufacturing applications. A machine tool is a machine for shaping metal or other materials, usually by cutting, boring, grinding, or shearing. The latest bearing design delivers higher spindle speeds, increased stiffness, and greater resistance to high temperatures. This allows the spindle to machine more material in less time while maintaining tolerances. Extra hard ceramic balls are available with steel races to make for an exceptionally accurate and long-lasting machine tool bearing.
The ceramic hybrid machine tool spindle bearings have 52100 series steel races and silicon nitride (Si3N4) balls. The benefits offered by ceramic hybrid machine spindle bearings include longer bearing life thanks to the ceramic balls eliminating the possibility of cold welding between the ball and race. Ceramic balls operate at lower vibration levels than steel balls, offering higher spindle rigidity. And because ceramic balls allow the bearings to operate at lower temperatures there is a longer lubrication life meaning there is less frequent maintenance required.
The engineers and experts at The Boca Bearings Company present their White Paper on Ceramic Hybrid Bearings in Machine Tools.
According to Boca Bearings’ founder Allen Baum the company has the “Largest off the shelf inventory ready to be shipped."
