Linearguidings are used to solve linearmovement-requirements in various fields of engineering and machine building. As they contribute significantly in designing a machine technically and commercially, linearguidings gained in importance these days. This catalogue introduces powerful linear-roundrail-components, mainly precision shafts, linear ballbushings, linear slidebushings, linear housing units and construction components, in 5 chapters. Besides the mentioned standardcomponents, also special designs are available. These will be manufactured following a customer-drawing or will be designed...

Technical Considerations Linear Technology Temperature and Friction The temperature range, these linear ball bearings are suitable for applications between -20 and +80°C. For higher temperatures we recommend all-steel bearings with special lubricants. The coefficient of friction depends on the quality of the seals as well as on pressure and lubrication. The linear bearings have a Coefficient of Friction of 0.001 to 0.005. Construction, Design and Materials Linear housings - aluminium extruded section Housing units can be fitted with all the linear bearings contained in this catalogue. Aluminium...

Technical Considerations Operating Life and Working Load for Linear Ball Bearings Linear Technology 1. The load is applied at 90° to the horizontal plane 2. The surface hardness is HRC 62±2. The following formula applies to configurations other than those given: WR = required dynamic load (N) P = resultant of externally applied loads (N) KS = hardeness factor of shaft K = factor for direction of resultant load Working Load The load conditions listed in the tables apply to the linear ball bearings described in this catalogue in combination with precision steel shafts. KL = factor for operating...

Technical Considerations Linear Technology Load Limit The load limit is the maximum load which may be applied to the bearing. Any application must be analysed in advance in order to ensure that maximum and / or shock laods will not exceed the load limits. Dynamic Load Conditions The dynamic load condition refers to the maximum continuos load which may be applied to a bearing, with a 90 % propability that a working life of 100 km can be achieved under normal operating conditions. However, it must be considered that extremly short strokes, and the direction of load application, are also deciding...

Load Calculation When designing a linear motion system, the way in which operating variables will influence performance must be considered. The following examples show how the posi- tion of the load and the load center can influence selec- tion of the product. When considering an application, every force acting on the system must be evaluated in order to enable the most suitable product to be selected. At the time of movement with uniform velocity or at the time of At the time of movement with uniform velocity or at the time of stop. Side Mounted Application At the time of movement with uniform...

Technical Considerations Linear Technology Shaft Deflection When using hardened precision steel shafts with end supports, care must be taken to ensure that the shaft deflection within the bearing travel does not exceed the bearing performance criteria. The following tables give the shaft deflection at the center of a shaft with end supports. Systems using fully supported shafts are not subjected to these deflections. Values of El for Hardened and Ground Shafts Shaft ∅ (mm) Simply Supported Shaft with Single Block Simply Supported Shaft with 2 Single Blocks

Technical Considerations Linear Technology Lubrication Oil-lubrication: Possible. Useful when a central lubrication system with oil is already installed. Our recommendation is Klüberoil GEM 1-68 N. All Linear Guiding Systems must be lubricated to ensure their function. The volume and the way of lubrication depends on the product. The definition of the re-lubrication, in terms of volume and cycles, are depending on the applications and can be calculated by our technical department. The information about grease- and oil-lubrication refer to standard industrial applications and are not obligatory....
