Product Description KGG High Quality Inverted Roller Screws-CHRI SeriesLoad Capacity Life The advantage of a planetary roller screw is the ability to provide higher dynamic and static load ratings than a ball screw. A threaded roller instead of a ball will allow the load to be released quickly through numerous contact lines, resulting in a higher resistance to impact. From Hertz's law of pressure, we can conclude that a planetary roller screw can withstand 3 times the static load of a ball screw and 1 1/2 times the life of a ball screw.Speed and Acceleration Planetary Roller Screws can provide higher rotational speeds and higher acceleration, and the lead length of a Planetary Roller Screw can be smaller than that of a Ball Screw. Since the lead of a planetary roller screw is a function of the pitch, the lead can be less than 0.5mm or less. The lead of a planetary roller screw can be designed to be calculated as an integer or fractional number (e.g., 3.32mm per transfer) and will not require a reduction gear to match. The change in lead does not introduce any change in geometry to the screw shaft and nut.In contrast, the lead of the ball screw is limited by the diameter of the ball, thus the lead will be standard.Stiffness and Strength The numerous contact lines of the planetary roller screw will substantially increase the stiffness and impact resistance. Application: CNC machine tools, robotics, aviation (aircraft/helicopter), aerospace (rocket/satellite), weaponry (tank/canon/missile/aircraft carrier/nuclear submarine). Precision injection molding machines, mechanical presses, medical industry, measuring instruments, special machine tools, laser equipment, petroleum industry, chemical industry, optical instruments, metallurgical equipment, automotive industry, servo-electric cylinders, etc.Technical DrawingSpecification List FACTORY DETAILED PROCESSING PHOTOS FAQ1.
