KITAGAWA BR SERIES POWER CHUCKS

The future of high-accuracy workholding has arrived with the Kitagawa BR Series Power Chucks—the next evolution of precision, performance, and productivity in CNC machining.

For over 50 years, the Kitagawa B200 Series Power Chucks have been trusted by the world’s leading machine tool OEMs and found on the most popular machine tool brands worldwide. Known for exceptional accuracy, long service life, and proven reliability, the B200 Series set the standard for high-performance workholding.

After years of research, development, and rigorous testing, Kitagawa introduces its flagship BR Series Power Chucks, engineered to surpass the performance of its predecessor and redefine what “high accuracy” truly means in metalworking.

UNMATCHED GRIPPING ACCURACY—AS A STANDARD

Many chuck manufacturers claim “high-accuracy” performance, yet few meet the benchmark already established by Kitagawa’s legacy designs. Industry standards for repeatability traditionally measured 20 microns when clamping, unclamping, and re-clamping a formed jaw workpiece.

The BR Series Power Chuck pushes this boundary even further—achieving gripping accuracy below 10 microns, with 0.01mm T.I.R. or less immediately after jaw forming as a standard specification.

This unprecedented level of accuracy makes the BR Series suitable not only for roughing, but also for high-precision finishing operations, eliminating the need to switch chucks between processes.

Note: BR12 models achieve gripping accuracy of 0.015mm T.I.R.

ELIMINATE JAW REFORMING WITH OPTIONAL TNUT-PLUS

The optional Kitagawa-patented Tnut-Plus system is a game-changer for setup efficiency and shop productivity.

Unlike conventional systems, Tnut-Plus allows soft jaws to be formed once—then removed and reinstalled without sacrificing accuracy. With Tnut-Plus, the BR Series maintains ≤0.01mm T.I.R. gripping accuracy even after jaw removal and reattachment.

Real-World Time & Cost Savings:

Assumes 3 setup changes per day

30 minutes per jaw forming cycle

1.5 hours saved per day

450+ labor hours saved annually

The result: thousands of dollars saved, reduced downtime, and more spindle time where it matters most.

DESIGNED FOR PERFORMANCE, BUILT FOR THE SHOP FLOOR

Beyond accuracy, the Kitagawa BR Series Power Chucks deliver a host of performance-driven improvements:

Extra-large through-hole (same as BB200 Series) as standard

Reduced jaw lift during clamping

Up to 15% reduction in grip force loss caused by centrifugal force

All-new chuck body design engineered for stability and longevity

Every BR Series chuck also features a distinctive rounded bevel design and the iconic Kitagawa “K” logo in branded blue—making it instantly recognizable on the machine.

For added convenience, each chuck includes an integrated QR code, allowing instant access to chuck-specific data, documentation, and specifications directly from the shop floor.

THE NEW BENCHMARK IN CNC POWER CHUCKS

With industry-leading gripping accuracy, dramatic reductions in setup time, and proven Kitagawa reliability, the BR Series Power Chuck sets a new benchmark for high-performance CNC workholding.

If your operation demands tighter tolerances, faster changeovers, and maximum productivity, the future is already here.
