• Convenience and high reliability are achieved by combining ball bearing and bearing housing.
• Since ball bearings for units have the same geometry as deep groove ball bearing, load rating, reliability, and other functions are equivalent to deep groove ball bearing.

• Plummer Block housings easily constitute bearing units by combining them with self-aligning ball bearings or spherical roller bearings.
• Accuracy, strength, and rigidity are improved by NACHI original design.

HyperDuAl SP Hob

• Capable of ultra-high-speed hobbing at a speed of 300 m/min or more, and high-efficiency hobbing of difficult-to-machine materials
• Demonstrates outstanding performance under harsh conditions
• Re-grinding and re-coating specifications (full coating)

HyperDuAl GP Hob

• Multi-purpose hob that can be used under any machining conditions, regardless of the cutting speed, work materials used, and whether a coolant is used or not
• Designed for use under general hobbing conditions (cutting speed: 80-180 m/min)
• Re-grinding and re-coating specifications (full coating)

• Energy saving.Power consumption: 50W(approx. 95% down)
• Low noise.57 dB(A) during operationZero noise during stop
• Low heat output .Oil temperature is room temperature + 7C
