This ensures not only a longer service life but also consistent performance under extreme conditions, such as elevated temperatures or aggressive environments This ensures not only a longer service life but also consistent performance under extreme conditions, such as elevated temperatures or aggressive environments
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
Stainless steel and other corrosion-resistant alloys were developed to withstand harsh operating conditions, while improvements in manufacturing techniques allowed for the production of smaller, more precise bearings Stainless steel and other corrosion-resistant alloys were developed to withstand harsh operating conditions, while improvements in manufacturing techniques allowed for the production of smaller, more precise bearings
. Speed rating, on the other hand, indicates the maximum rotational speed the bearing can withstand. The clearance, or the small gap between the inner and outer rings, affects the bearing's running accuracy and temperature rise during operation.
