LINEAR SYSTEM LINEAR SYSTEM PROCESS FOR SELECTING NB LINEAR SYSTEM Check the application conditions The NB linear system is a linear motion mechanism which utilizes the rotational motion of ball and/or roller elements. NB offers a wide range of linear motion products of high precision quality that contribute to the size and weight reduction of machinery and equipment. Decide system type ADVANTAGES Low Friction and Excellent Response Despite the compactness of the NB linear system, the system uses relatively large rolling elements on a long raceway resulting in a high load capacity and a long...

LINEAR SYSTEM ALLOWABLE LOAD LIFE Load and Moment Figure 1-1 Load and Moment A load is applied to the linear system as Figure 1-1 shows. Sometimes moment loads are applied to, for example, slide guides. Load and moment are defined as follows. Basic Static Load Rating (compliant with ISO14728-21) and Allowable Static Moment When excess load or impact load is applied to the linear system while it is stationary or moving slowly, a permanent deformation occurs on the rolling elements and the race way. If this deformation exceeds a certain limit, it causes vibration and noise during operation resulting...

LINEAR SYSTEM ・ 3 10 Lh 2・ L ・n1・60 …………………… 9 ℓS L h: life time hr ℓ : stroke length S m　 cpm n1: number of cycles per minute In the linear system, the guide rail or shaft works as race way of the rolling elements. Therefore, the hardness of the rail or shaft is an important factor in determining the rated load. The rated load decreases as the hardness decrease below 58HRC. NB products hold appropriate hardness by advanced heat treatment technology. In case of using the rail or shaft of insufficient hardness, please take the hardness coefficient (Figure 1-2) into the life calculation equation....

LINEAR SYSTEM RATED LIFE CALCULATION EXAMPLE 1 ●Average Applied Load 2 Horizontal Axes, 2 Blocks each, Considering Acceleration/Deceleration The load applied to a linear system generally varies with the travel distance depending on how the system is operated. This includes the start/stop processes of the reciprocating motion and work on the system. The average applied load is used to compute the life corresponding to the actual application conditions. ①When the load varies in a step manner with the travel distance (Figure 1-7). 　　ℓ1 is the travel distance under load P1 　　ℓ2 is the travel distance...
