and ball screws with its extra large line of products.
THK's large scale Type SNS300 LM Guide is the company's largest LM Guide with caged ball technology. The SNS300 features a height of 300mm, a block width of 540mm, a block length of 976mm and a rail width of 300mm. The Type SNS features a four-direction, equal load rating.
THK's heavy load ball screw Type HBN has a large load capacity due to the optimized design of its internal structure. In heavy load durability tests (118kN load, 48mm stroke, 3.8m/min max), the Type HBN performed 100,000 cycles. Test operations at high ambient temperatures found movements to be identical at 20° and 80°C temperatures. Improved energy savings, positioning accuracy, clean operation, enhanced machine control and reduced maintenance all make the Type HBN interchangeable with hydraulic cylinders. THK's ball screw achieves an increase in maximum nut RPM (130,000 DN). The Type HBN is available in sizes up to 12025.
THK's caged technology employs a synthetic resin cage with a patented curvature that cradles each ball and separates it from the next. The spaces between the rolling elements retain grease and act as a lubrication system for long-term maintenance-free operation. Other caged technology benefits include reduced noise, increased speed and accuracy of motion, rigidity, reduced dust generation and smooth movement.
