定义
设计用于集成到滚珠丝杠或导螺杆系统中的滚珠轴承,这些系统将旋转运动转换为精确的直线运动。这些轴承支撑丝杠轴,承受轴向和径向载荷,并在工作应力下保持对中。它们具有精密磨削的滚道和高等级滚珠,以确保在苛刻的工业应用中实现最小间隙、高刚性和长使用寿命。

基于精密滚珠与淬硬滚道之间的滚动接触原理。当丝杠旋转时,滚珠在轴承内循环,将滑动摩擦降至接近零的水平。这使得运动和力的传递具有高精度和高重复性,同时均匀分布载荷以防止局部磨损。
工作原理
Operates on the principle of rolling contact between precision balls and hardened raceways. When the screw rotates, the balls circulate within the bearing, reducing sliding friction to near-zero levels. This allows efficient transmission of motion and force with high accuracy and repeatability, while distributing loads evenly to prevent localized wear.
材料
通常由铬钢(AISI 52100或等效材料)制成滚道和滚珠可选不锈钢(AISI 440C)以提高耐腐蚀性。保持架可由压钢、黄铜或工程聚合物(如聚酰胺)制成。密封件通常为丁腈橡胶或氟橡胶以防止污染。

常见问题

What is the difference between ball bearings for ball screws and standard radial bearings?

Ball screw bearings are optimized for high axial load capacity and precision alignment, with tighter tolerances (e.g., ABEC 5 or higher) and often preloaded designs to minimize backlash, unlike standard radial bearings which prioritize radial loads.

How often should ball screw bearings be lubricated?

Lubrication intervals depend on operating conditions: typically every 3-6 months for general use, or more frequently in high-speed, high-load, or contaminated environments. Use grease compatible with bearing materials (e.g., lithium-based for steel).

Can these bearings be used in high-temperature applications?

Standard chrome steel bearings operate up to 120°C; for higher temperatures (up to 250°C), specify bearings with heat-stabilized materials like AISI 440C stainless steel or ceramic balls, and high-temperature lubricants.
