PBC线性启动微型度量标准球螺钉组件

PBC Linarear是一家太平洋轴承公司，也是线性运动解决方案的全球领导者，已扩大其全面的投资组合，包括微型度量标准球螺丝组件。在其铅螺钉技术的成功基础上，精确螺丝螺钉和紧凑螺母的这种结合从经济包装中推动了出色的性能。复杂的实验室设备，医疗设备，半导体和其他自动化应用程序的制造商将发现这些高精度球螺钉是针对其小规模线性运动需求的有价值的解决方案。此外，PBC线性提供较短的交货时间，这是通过其圆螺钉生产过程和中西部中部位置完成的，其中许多产品经过了工程和生产。

设计和选项
As with lead screws, ball screw assemblies are used to convert rotational motion to linear motion. They typically include a ball nut, threaded shaft, and a recirculating system that utilizes a continuous movement of balls to transfer forces and propel the nut along the screw. Each ball screw and nut are engineered with gothic arch threads that define the track of the nut and screw thread, offering high rigidity, durability, and duty cycles. The main benefit of ball screws is higher efficiency and accuracy, making them ideal for a variety of industrial and automotive applications.

PBC线性目前提供直径为6毫米，8毫米和10毫米的微型球螺钉，并提供铅长度和螺母类型的选项。此外，可以为独特的客户需求提供标准和特殊的加工期刊。其他选项包括固定或浮动端块。

The other half of the ball screw assembly consists of the nut. Miniature metric ball screw nuts from PBC Linear feature two types of ball return systems to accommodate shorter or longer leads. Short leads are synonymous with internal multiliner returns, and long leads are represented in our end-cap return system.

Each are available in flanged or cylindrical configurations, with optional end support blocks and bearings. Flange-style nuts can often be easier to remove and install in an assembly, provided the assembly can be designed so that the mounting screws or bolts can be easily accessed. Cylindrical nuts allow for a more compact assembly design as there is no flange.

Dynamic load ratings在确定用于应用的正确微型球螺钉时，是一个重要因素。PBC线性将基于1,000,000 Rev（n）在该产品家族中提供保守的动态负载额定值。这确保了那些希望在系统中实现微型球螺钉的人，可信赖，可靠的性能。

Ball screws from PBC Linear come standard without preload (backlash clearance held to 0.05 mm MAX). We offer a Preload option that offers higher rigidity and better positional accuracy, but at the expense of slightly diminished load capacity. This P-type preload uses oversized balls to preload the assembly up to 3% of dynamic capacity.

标准和测试
PBC线性球螺钉组件符合10年级和7年级的标准ISO准确性。此外，客户可以就5类精确度与应用程序工程师联系。为了满足行业需求，PBC线性利用高端测试设备，例如钥匙式光学比较器，Mitutoyo线程形式示踪剂和自定义动态铅检查器，可分析每米高达15,000点。

PBC线性uses a high-precision CNC roll threading process for the most consistent thread forms and high accuracy rate. They also measure and record 100% positional accuracy along the entire travel length of the screw
