The width of the bearing is also critical; it must be sufficient to support the load and resist deformation under operational stresses The width of the bearing is also critical; it must be sufficient to support the load and resist deformation under operational stresses
However, if bearing prices are too high, manufacturers may find it difficult to invest in research and development, which could limit their ability to introduce new and improved machinery products However, if bearing prices are too high, manufacturers may find it difficult to invest in research and development, which could limit their ability to introduce new and improved machinery products
