转盘轴承安装前，先要对主机的安装面进行检查，要求支承件应具有足够的强度

Mounting the front wheel bearings, first mounting surface of the host checks, it requires the support member should have sufficient strength, even <br>surface to be machined, smooth surface free of debris and burrs. For flatness can not achieve the required machining, the <br>possible use of special high-intensity injected plastic as fillers, to ensure accuracy and mounting surface for the damping. <br>Quench wheel bearing rings flexible bands, so that the end surface of the ferrule which are marked "S", the user should install <br>the flexible belt position in a non-regular or non-load zone in the load zone (always in the plug hole soft belt at). <br>When mounting wheel bearings, positioned to be advanced acts, cross Tighten the screws, and check the rotation of the bearing. <br>Tightening the bolt should have adequate preload, the preload which should yield 70% limit bolt material. Mounting bolts should be equipped with <br>the use of non-tempered spring washer flat washer.

Before the turntable bearing is installed, the mounting surface of the main frame should be checked, requiring that the support should have sufficient strength, even The face should be machined, the surface is flat without debris and burrs.<br>For those who cannot mechanically achieve the required flatness,<br>Fillings can be made with special plastics with strong injection strength to ensure the accuracy of the installation plane and to reduce vibration.<br>The collar of the turntable bearing has a quenched soft band area, which is marked "S" on the end face of the collar, and the user should make the installation<br>The soft band position is placed in the non-load zone or non-regular load area (stopper holes are always located at the soft belt).<br>When installing turntable bearings, the mounting bolts should be positioned in an advanced way, and the swing of the bearings should be checked. The bolt should have sufficient pretension force when tightening, and the pretension force should be 70% of the yield limit of the bolt material.<br>Mounting bolts should be used The use of spring washers is not strictly prohibited by conditioning the flat washers.

Before the installation of the rotary table bearing, the installation surface of the main engine shall be inspected first, and the supporting parts shall have sufficient strength.<br>The joint surface shall be machined and flat without sundries and burrs. If the required flatness cannot be achieved by machining,<br>Special plastics with high injection strength can be used as fillers to ensure the accuracy of installation plane and to reduce vibration.<br>The ring of the rotary table bearing has a quenching soft belt area, which is marked with "s" on the end face of the ring. When the user installs it, he should<br>The soft belt is located in the non load area or non frequent load area (the plug hole is always located in the soft belt).<br>When installing the bearing of the rotary table, the radial positioning shall be carried out first, the mounting bolts shall be tightened crosswise, and the rotation of the bearing shall be checked.<br>Sufficient pre tightening force shall be provided when tightening the bolt, and the pre tightening force shall be 70% of the yield limit of bolt material. Mounting bolts shall be equipped with<br>It is forbidden to use spring washer for tempering flat washer.<br>
