About Ground ball screw with double nut
In its most basic form, a double ball nut is essentially two single ball nuts that have been tensioned against each other to induce preload. Three common methods for inducing preload in a double nut are: With a spacer ring between the ball nut halves. With a spring between the ball nut halves.Unmatched Precision and StabilityDelivering ultra-precise linear motion, this ground ball screw features a double preloaded nut, achieving zero axial clearance for highly stable and repeatable positioning. The 0.003mm lead accuracy and ISO 3408 Class 1-3 rating exceed demanding industry standards in CNC and automation.
High Load Capacity and DurabilityDesigned for heavy-duty requirements, this ball screw handles dynamic loads up to 75 kN and static loads up to 142 kN, depending on the chosen size. The component is manufactured from hardened alloy steel (HRC 58-62) and is polished for an extended service life, with optional anti-corrosion coatings.
Versatile Configuration and Easy MaintenanceWith customizable screw sizes and maximum lengths up to 6 meters, this solution fits a broad spectrum of machinery. Internal ball recirculation reduces noise, while grease fittings or central lubrication connections ensure effortless and consistent maintenance.
FAQ's of Ground ball screw with double nut:
Q: How does the double preloaded nut benefit my application?
A: The double preloaded nut ensures there is absolutely zero backlash (axial clearance of 0 mm), enhancing positional accuracy and repeatability. This is particularly crucial in CNC machinery, robotics, and high-precision automation setups where precise motion control is required.
Q: What is the process for maintaining lubrication in the ball screw assembly?
A: This ground ball screw integrates a grease fitting for regular lubrication and also supports central lubrication systems for automated or high-duty installations. Proper lubrication, following the recommended intervals, guarantees smooth operation and prolongs the lifespan of both screw and nut.
Q: Where is this ground ball screw typically used?
A: These ball screws are widely applied in CNC machines, robotics, positioning systems, and automated equipment, where high precision, load capacity, and low noise are required. Their robust design also makes them dependable in demanding industrial environments.
Q: What sizes and configurations are available for different machinery needs?
A: The screws are available in diameters from 12 mm to 40 mm and can be customized in length up to 6 meters. Standard head sizes correspond to each model, and further customization options can be discussed for unique machine requirements.
Q: What is the benefit of the internal ball recirculation design?
A: Internal ball recirculation ensures seamless rolling motion with minimized noise and reduced wear. This design improves operational quietness and efficiency, making it ideal for sensitive or noise-restricted environments.
Q: When should I consider an anti-corrosion coating for my ball screw?
A: Anti-corrosion coating is recommended when the ball screw will operate in humid, chemically aggressive, or outdoor environments. This optional finish helps protect the component against rust and extends its operational life in challenging conditions.
Q: What quality standards are followed in manufacturing this ball screw?
A: The screws are manufactured to ISO 3408 Class 1-3 quality levels, ensuring high lead accuracy, durability, and consistency. This strict adherence results in reliable performance, especially crucial for precision motion applications.
