Bearing tolerance, bearing size accuracy and rotation precision is according to ISO and JIS standard. Asking for high precision and high speed running of the machine, it is recommended to use level 5 or more precision of the bearing, deep groove ball bearings, thrust ball bearing to the heart or cylindrical roller bearings are used in high precision operation of the machinery. Rigid, when the roller bearing and groove surface under pressure, can produce elastic deformation. Some mechanical will need to minimize elastic deformation. Roller bearing than the ball bearing effects of elastic form variables small.

In addition, in some cases bearings are applying preloading to increase rigidity. The program usually used for deep groove ball bearings, thrust ball bearing and heart to taper roller bearings inside and outside circle bias, shaft bending, shaft or bearing box tolerance change, with mistakes will lead to internal and external to the eccentricity of the circle. To prevent eccentric Angle is too large, automatic self-aligning ball bearings, automatic self-aligning roller bearings, or self-aligning bearing is a better choice. Voice frequency and torque is, rolling bearings are according to the standard of high precision manufacturing, so voice and torsion small. Deep groove ball bearings, and cylindrical roller bearing for low voice to apply, low torque with special demands of the occasion.

 

Installation and removal, some applications need often remove and installation to ensure that we can periodically testing and maintenance. Can be installed inside and outside circle respectively bearing such as: cylinder bearing, needle bearing, and cone bearing very applicable to this occasion. Cone shape automatic self-aligning ball bearings and automatic spherical roller bearing in under the help of the collar, also simplified installation procedures.
