Rollon 重新设计 TV 系列滚珠丝杠执行器，提升力矩负载能力
Rollon redesigns TV actuator series for higher load capacity
Rollon 重新设计并推出 TV 系列滚珠丝杠驱动执行器，提供 65、80、110 三种规格，重点提升力矩负载能力、防护性能与整体表现。重新设计将两个直线导轨滑块布置在彼此尽可能大的间距上，滚珠丝杠螺母位于两者之间，形成更宽的支撑跨距以承受更高力矩负载。内部组件防护新增聚氨酯密封带，该方案已在 Rollon 其他执行器系列中使用，密封带由滑座内的微型轴承保持位置，在穿过滑座时阻力最小，同时保护滚珠丝杠驱动与直线导轨系统免受污染物侵入。新产品可选不同滚珠丝杠导程，以适应不同速度和负载需求；更长行程版本可选内置滚珠丝杠支撑，减少丝杠挠曲，从而实现更高运行速度。TV 系列定位重复精度达 5μm，直线导轨配两个预紧循环滚珠轴承滑块，方形截面提供刚性导向，直线导轨与滚珠丝杠均设专用润滑通道。该系列适用于工业自动化、包装和机器人等需要精确可重复直线运动的场合。Rollon 首席技术官 Andrea Tosi 表示，此次重新设计通过优化滑座架构和引入新密封系统，提升了系列的性能与可靠性。

Rollon, a global leader in linear motion solutions, announces the launch of its redesigned ball-screw-driven TV actuators, featuring enhancements aimed at increasing moment load capacity, protection and overall performance. Available in sizes 65, 80 and 110, the TV line is designed for precise and repeatable motion across a range of industrial applications.
The redesign increases the moment-load capacity of the actuators. The two linear guide blocks are positioned at the maximum possible distance from each other, with the ball screw nut located between them, creating a wider support span to accommodate higher moment loads.
Protection of the internal components has also been enhanced with the introduction of a polyurethane sealing belt, a proven solution already used across other Rollon actuator lines. The belt protects the ball screw drive and linear guide system from contaminants and is kept in position by micro-bearings inside the carriage. This configuration minimises resistance as the belt passes through the carriage while maintaining effective protection of the internal components.
The redesigned TV actuators are available with different ball screw leads, providing greater flexibility to meet varying speed and load requirements. Additionally, for longer strokes, an optional internal ball screw support helps reduce shaft deflection, enabling higher operating speeds. TV actuators are suitable for a wide range of applications requiring precise, repeatable linear motion, particularly in industrial automation, packaging and robotics.
Andrea Tosi, chief technology officer at Rollon, said: “This redesign marks an important evolution of the TV series, with a focus on increasing moment load capacity while providing greater protection for the actuator’s internal components. By optimising the carriage architecture and introducing the new sealing system, we have enhanced the performance and reliability of the series to better address the requirements of demanding automation applications.”
The TV actuator range combines a rigid construction with high precision and reliability, making it suitable for demanding linear motion applications. Its linear rail with two preloaded recirculating ball bearing blocks, together with the square cross section, provides a rigid guidance system, while positioning repeatability reaches 5μm.
Reliability over time is also supported by dedicated lubrication channels for both the linear rail and ball screw, facilitating maintenance of the unit. With its redesigned architecture, the TV series gives machine designers greater flexibility to meet the precision, load and speed requirements of different automation applications.
