1, push rafah
The pushing method is generally used for positive clearance, and the axial clearance between the bearing raceway and the rolling body can be measured. Apply a force to the shaft or bearing seat in one direction, push the dial indicator to zero for reference, and then apply a force in the opposite direction, push the dial indicator after the rotation is the value of the gap. Oscillate the rotating roller slowly during measurement to ensure that the roller is correctly positioned on the inner rim
2, Acro - SetTM method
The theoretical basis of ACro-set is Hooke's law, which states that the shape variable of an elastic deformable object is proportional to the external force. The spacer or spacer clearance is measured to obtain the correct clearance under a certain mounting force. Read the correct spacer or spacer dimensions as required directly from a diagram created during the prior test
3, the Torque - SetTM method
Torque-set is based on the principle that, under preload, the rotational Torque of the bearing increases as a function of the preload of the bearing. The experimental results show that for a group of new bearings of the same type, under the condition of given preload, the rotational torque of bearings changes very little. Therefore, rotational moments can be used to estimate precompactness
