The ball screw is also very reliable and requires almost no maintenance. It is recommended to use a wiper kit or an integrated wiper together with a ball nut to prevent contamination of the interior by foreign matter potentially damaging materials. In order to maintain the best ball screw performance, lubricant must be used. Without proper lubrication (usually oil or lithium grease), the expected life of the ball screw will be lost by 90 percent . The standard lubrication process for anti-friction bearings is suitable for ball screws. Depending on the actual ball screw application, it may also be necessary to ensure a corrosion-resistant coating and/or lubricated surface treatment.
Always ensure that the ball screw is operated within the recommended temperature range. The thermal expansion of the screw can cause positioning errors. By keeping the working temperature of the screw within the specified range, design engineers can avoid this situation, ensure that the lubrication works properly, and achieve reliable and reliable performance.
Precision ball screws are still the "preferred" solution to meet the unique linear motion control requirements of medical/laboratory applications. However, choosing the most suitable ball screw configuration for specific needs requires an objective assessment of the application requirements and the corresponding ball screw characteristics. By understanding the scope of the key factors discussed in this article, design engineers will not only meet their linear actuation needs, but will also implement the most effective, cost-effective, and reliable solution to control motion in their medical or laboratory equipment. .
Industrial linear actuators promote linear motion, while conventional motors move in circular motion. When considering the use of linear actuators instead of electromechanical systems of other technologies, there are multiple ways to solve an application. All changes differ in accuracy, speed, load and cost. This will ultimately guide the choice of linear motion solution type.
