This Gilman block spindle is grease lubricated and capable of running up to 5,000 rpm. We can improve the contamination prevention properties of Gilman spindles to help improve the lifespan of the spindle in your machine.
CHALLENGE
This Gilman block spindle arrived at Northland Tool and Electronics in pretty rough shape. The first thing we noted was that the pilot was pitted in the relief area but the contact area with the tooling was functional. Second we noted, the air purge was plumbed with hard tubing that was destroyed upon arrival. We can not duplicate the tubing because of this, but we can replace the metal tubing with plastic. Lastly, the bearings were noted as severely contaminated. No dimensional deviations were noted for this repair.
SOLUTION
The following actions were performed on this Gilman Block spindle:
- Clean all parts of the spindle
- Replace bearings, o-rings, and assembly screws
- Replace seals and tubing made of plastic for air purge
RESULT
After reassembly of all components, adjusting bearing preload, and undergoing break-in and testing procedures, this spindle passed our final quality inspection before being returned to our customer with a 1-year warranty.

It’s a fact of machining — eventually, even top-of-the-line turning machines will experience a spindle failure. Spindles endure tension, torsion, heavy loads, and speeds up to and beyond 150,000 RPM, to name a few of the standard stressors.
