THK's New Heavy Load Ball Screw Type HBN with Caged Technology Outperforms Hydraulic Cylinders

Schaumburg, IL (August 16, 2002) - THK's new Heavy Load Ball Screw Type HBN with Caged Technology features improved energy savings, superior positioning accuracy, clean operation, enhanced machine control and reduced maintenance. Because of these features, the Type HBN outperforms hydraulic cylinders.

With the high thrust feeding speeds and durability of a hydraulic cylinder, the Type HBN goes where no conventional ball screw has ever gone before. The Type HBN is uniquely designed for use in injection molding, pressing, blow molding and die casting machines.

THK's revolutionary Caged Technology is the secret to the Type HBN's success. This ball screw achieves a maximum of 130,000 DN.

THK's Caged Technology acts as a reservoir for lubricants, eliminating the need for an external lubricating system. Specific benefits include increased speed and accuracy of motion, decreased noise levels, long-term, maintenance-free operation and reduced sources of contamination.

To improve the rating load of their ball screw, THK optimized the design of its internal structure. In heavy load durability tests (118kN load, 48 mm stroke, 3.8m/min max. travel speed) the Type HBN performed 1,000,000 cycles without any problems. Test operations at high ambient temperatures found movements to be identical at 20°C and 80°C temperatures.

The Type HBN is available in diameters from 32 to 63 mm and leads from 10 to 20.
