Ajuste do rolamento 639

A necessidade de uma coordenação correta
Generally speaking, only when the fit between the bearing and the shaft has an appropriate amount of interference, satisfactory radial positioning and appropriate support can be obtained. Improper or incorrectly fixed inner and outer rings of the bearing will usually cause damage to the bearing and its accessories. Careful research must therefore be done when selecting the correct fit. Listed below are some bearing failures caused by incorrect fits.

Cracks appear in the raceway, early spalling and raceway displacement.
Due to incorrect fit, the internal clearance becomes negative and the bearing is burned.
Wear occurs due to deformation and abrasion between the bearing and shaft or bearing box.
Causes deformation of the raceway, resulting in increased noise levels and reduced rotation accuracy.

Condições para rotação e ajuste
Rotating conditions consider the relationship between the bearing ring and the direction of the load, usually including “rotating load” and “static load”. Bearing components under rotating load conditions usually use an interference fit to prevent bearing slippage. At the same time, under static load conditions, clearance fits may also be used to adapt to specific operating conditions or to facilitate the installation and disassembly of bearings.
