The Spindle Bearing

Angular contact spindle bearings are bearings of remarkable speed accuracy and precision Though seemingly simple they are in fact complex components that enable and support a remarkable range of sophisticated manufacturing processes The great value of angular contact spindle bearings is their ability to handle loads in both the radial and axial directions (see Fig 1)

Super-precision angular contact ball bearings are typically located axially on shafts or in housings with either precision lock nuts or end plates These components require high geometrical precision and good mechanical strength to provide adequate support and location

Spindle bearings are single row angular contact ball bearings comprising solid inner and outer rings and ball and cage assemblies with solid window cages They cannot be dismantled The bearings are available in open and sealed versions Spindle bearings have restricted tolerances They are particularly suitable for bearing

A spindle assembly ( 20 ) adapted to be mounted on the rotatable head ( 21 ) of a Davenport multi-spindle automatic screw machine broadly includes a one-piece outer spindle ( 38 ) a seal member ( 39 ) a front bearing assembly ( 40 A 40 B 40 C) a front bearing retainer nut ( 41 ) forming with the seal member a tortuous passageway ( 85 ) a two-part spacer ( 37 ) a rear bearing assembly

How to Replace Damaged Bearings on a Precision CNC Spindle We see a lot of forums with questions concerning how to replace bearings on a CNC spindle So we've decided to write a few blog pages that we hope will be helpful for the shops that want or need to DIY

2000-3-1In order to minimise the sources of vibration the spindle is configured as a non-contact drive system where the rotor is supported by pairs of angular contact ball bearings in a tandem arrangement at each end and in a back to back formation providing a high dynamic stiffness The bearings are grease lubricated for spindle speeds up to 20 000

2011-2-5Auto supply bearings are fine for cars and most other stuff but not for spindle bearings 0 0017 random runout is not that uncommon for low grade taper roller bearings but no good for a lathe spindle OK I was all wet ranting on and on about leaving sleeping spindle bearings lie Better replace those dud bearings with real spindle grade bearings
