About HST Spindles

HST Spindles is an independent spindle repair facility with over 50 years of experience. We specialize in both mechanical and air-bearing spindle repairs for numerous industries. Each senior technician is OEM-trained with more than 15 years of experience. We have repaired more than 100,000 spindles of virtually every type and model. A production-critical spindle can be repaired in 3 days.

By analyzing the cause of failures, we can prevent future failures and improve spindle performance. We balance and analyze your spindle with modern equipment. We grind to micron precision in-house. With calibrated and certified test equipment and a climate-controlled work area, our Certified Big Plus spindle repair shop meets OEM specifications. For rolling element bearings, we use ABEC 7 or better. On repaired spindles, we meet or exceed OEM warranties.

We're big enough to handle all machine tool spindle rebuilds and repairs, but small enough to know every customer personally.
