Belt driven or motorized, block or cartridge, with over fifty years EXPERIENCE we have the expertise to handle all your precision spindle rebuilding needs. Our reputation is more than engineering, tooling, or technique; it's tempered with pride for a job well-done and a speedy return of your investment safely and on time. You can count on Sopko for performance.

Whether it's routine preventive maintenance or an unexpected spindle failure, our service department is dedicated to fast turnaround. An extensive inventory of spindle parts, including ABEC 7 and ABEC 9 precision bearings combined with a "Do It Right the First Time" philosophy is how we define SERVICE.

Our precision spindle specialists have rebuilt the world's most sophisticated spindle systems. We understand precision tapers, tolerances and bearing pre-loads, and we have perfected our process management to assure you of only the highest standard of QUALITY.

At Sopko we're constantly aware of providing customers with value. Downtime is expensive and nothing is more valuable than workmanship you can trust. We provide a fair, no-charge estimate for you to approve before work begins. You can count on Sopko to do the job right the first time-every time. That's real ECONOMY.

• Disassembly - We completely tear down, clean and inspect each component part.
• Evaluation - The spindle is systematically evaluated and you are quoted a firm price for rebuilding.
• Restoration - As needed, the process includes hard chrome plating, regrinding of bearing journals and housing bearing bores. Our grinding professionals hold an accuracy of 0.000050" on internal diameters. Finished spindle shafts are balanced on a computerized Hofmann H10BK.
• Assembly - We use ABEC7 and ABEC9 precision bearings. All assembly is done in our environmentally controlled "clean-room". A run-in period tests every spindle at rated RPM for balance, bearing temperature and critical runout.
• Shipping - We use a High-Density Foam-in-Place packaging system to protect your spindle during shipment. This high performance system blocks and braces your investment to provide superior shipping protection.
