1高依赖性
滚珠丝杆是以多年来所积累的制品技术为基础,从材料、热处理、制造、检查至出货,都是以严谨的品保制度加以管理,因此具有高依赖性。
2圆滑的动作性
具有比传统螺杆更高的效率,所需扭矩只有30%以下。可轻易将直线运动转变为回转运动。滚珠螺杆即使给予预压,亦能维持圆滑的动作性。
3无背隙与高刚性
采用哥德式沟槽、轴方向隙调整做预压调整。又于1个或2个螺帽做预压调整,给予消除轴方向间隙,使其具有可符合使用适当刚性。
4循环方式
外循环方式
内循环方式
5优异的耐久性
以累积多年的滚珠丝杆之生产技术为基础,采用严谨的材料高度热处理及加工技术,可供给耐久性的制品

精密滚珠丝杆的导程精度,以JIS规格为基准,并由四个特性项目加以规定。各特性之定义与容许值。一般用滚珠丝杆之累积导程误差。仅以螺杆之有效长度内任取300mm的误差容许值和表加以规定,各以0.05mm及0.21mm。
