Ball bearings

Angular Contact Ball Bearings

A shoulder-relieved raceway takes combined load at speed. Used in pairs or trios, it is the standard answer for a spindle that has to be stiff in both directions and still run cool.

Design

Matched, preloaded, at speed.

Every batch is measured on the finished part, and the measurement file travels with the goods. Send a designation, a drawing or a photo of the failed part and an engineer will answer with a lead time and a price, usually inside 48 hours.

  • 15°, 25° and 40° contact anglesShallow for speed, steep for axial stiffness — chosen against the actual load case.
  • Universal matchingPairs and trios matched for preload so they can be mounted in any order.
  • Preload classesLight, medium and heavy preload, each with a measured starting torque.
  • P4 running accuracyFor spindle noses where runout shows directly on the workpiece.

A designation, a drawing, or a photo of the failed part is enough to start. Technical questions reach an engineer, not a mailbox.
