    Support Unit Introduction

     

    ♦   Preload selection and applications

         - Light (L)

              * Machine Requirements:Equipments with small vibration and small thrust, load in one fixed direction. High accuracy is not required. Reduction of frictional force.

              * Application Examples:Laser welder, small CNCmill machine, cutter, welder, automatic tool changer, packing machine, material supply equipment.

         - Medium (M)

              * Machine Requirements:Equipments with load on a post. Equipments with a torque acting on it. Equipments working in one direction. Equipments with low load. Equipments with high accuracy.

              * Application Examples:Automated feeder, linear feeder, automatedpainting machine, precision slide table, Z-axis control on machines, PC board punch machine. Industrial robot, EDM machine, NC lathe.

         - Heavy (H)

              * Machine Requirements:High rigidity, high vibration, high thrust equipments. High load, high torque equipments.

              * Application Examples:Machining center spindle, NC lathe, Z-axis spindle of the machinery, milling machine, grinding wheel feeding of grinding machine.

     

    ♦  Pre-Loaded Description

         - Purpose:1. Increase the rotational accuracy of axle

                            2. Increase the rigidity of axle

                            3. Reduce unwanted clearance

                            4. Reduce vibration and noise while bearing stops.

         - What is bearing preload?:The preload describes the process wherein a permenant thrust road is applied to the bearing, so that the bearing is secure in the groove and has no axial clearence. Apply normal force (N). Measure value of L of a pair of bearings. L=L1+L2. Press these pair of bearings on the covers to apply preload and bring these bearings together

     

    ♦   Selection Notes

    - [ Model ]:Pick up the model according to assembly method.

       Assembly:

              1. Plane mounting:GAK、GBK、GEK、GAF、GBF、GEF、GSW、GSWE、GUN、GTN。

              2. Suspension and spindle mount:GFK、GFF、GRW、GRWE、GUR、GTR。

    - [ Size ]:Decide the size according to the ballscrew shaft O.D., and the center height.

    - [ Grade ]:Standard and economic types for options.

    - [ Pre-loaded ]:Decide pre-loaded of the bearing per needs.

    - [ Surface Finish ]:

                        Black dyed - Regular environment use, low humidity.

                        Nickel plating - Clean room use.

    - [ Bearing category ]:Available Japanese series and Taiwanese series.
