Double direction angular contact thrust ball bearings were developed by SKF to axially locate machine tool spindles in both directions. In these applications, a high degree of system rigidity is one of the main performance challenges, as the magnitude of elastic deformation under load determines the productivity and accuracy of the equipment. To keep up with the ever increasing performance challenges of precision applications, SKF developed a new generation of double direction angular contact thrust ball bearings. These super-precision bearings in the BTW series have a new, optimized design enabling them to accommodate higher speeds compared to bearings in the
former 2344(00) series. The benefits of the new design are evident by the improved overall bearing performance.
Bearings in the BTW series are characterized by:
• high-speed capability
• high axial load carrying capacity
• high stiffness
• low friction
• extended bearing service life
Bearings in the BTW series provide excellent
reliability and superior accuracy for various
applications, including surface grinding
machines, milling machines, machining
centres and lathes.
