Spindle Repair & Engineering Services
UPSPL repairs high speed and precision spindles comprises of grinding spindles, boring spindles, milling spindles, machine tool spindles as well as wood router spindles, and other high speed or high accuracy rotating devices.



We work with you to achieve increased spindle life and performance. Needless to mention, that does substantially reduce the number of spindles we rebuild, but it does create long term business relationships. UPSPL has been providing service with integrity since 1993.

We attend to every detail with an obsession for cleanliness, dimensional accuracy and geometric perfection. Our advanced inspection procedures and experience allow us to determine the root causes of failure. We use this information to help you save money.

With tolerances measured in microns, bearings and spindles will perform as expected only when every detail is attended with hyper-critical attention.  Precision bearings rely on extremely small tolerances. That is why spindle rebuilders need specialized knowledge, experience and equipment, which UPSPL certainly has.

The spindles are assembled in clean rooms. Contamination of any size, damages bearing components. Also bearing inner & outer rings conform to the roundness of their mating components. Poor shaft or housing geometry will distort the bearing. Improper fits change preload and reduce bearing life.  Super precision bearings demand a super precision environment. UPSPL has complete infrastructure including Ultra Sonic washing machines, oil injection equipments, hydraulic pusher/puller and other special tooling to disassemble and assemble spindle with utmost precision.
