cylindrical roller bearings manufacturer with up to three times longer service life than the previous SKF standard, which is super­ior to all other conventional cylindrical roller industrial bearings. The performance improvements of SKF cylindrical roller bearings over the past 50 years have permitted downsizing, whilst still main­taining the required performance diagram fT).

contact profile ^^^h
This important fea­ture of SKF cylin­drical roller bearings - for the past twenty-odd years - has been further refined for the rollers used in SKF Explorer bearings. The bearings are thus even less sensitive to small mis­alignment and can carry heavy loads.
SKF Explorer bear­ings feature an extremely clean
and homogenous steel with a minimum number of inclusions. This improved steel is so much cleaner than the high­est grades covered by present classi­fications. The reduction in the number of inclusions increases the fatigue strength in the rolling contacts and enables the bearings to operate much longer.
Heat treatment
New heat treatment | procedures opti­mize the bearing resistance to operational damage and temperatures without affecting dimen­sional stability.
Roller end/flange geometry
The optimized roller end/flange contacts of SKF cylindrical roller bearings are also present in SKF Explorer bearings. The resultant advantages include re­duced friction, lower operating tempera­tures and less wear.

have contributed to a significant im­provement in product quality. This means that the rings can be produced with an increased roundness and the deviation from true form of the rollers has also been further reduced. The results of the tighter tolerances may be invisible but the bearings run markedly quieter and with less vibration.
cant impact on a bearing's ability to withstand given operating conditions. That is the reason for making SKF Explorer bearings available with up to four different cages. The design of the cages used in SKF Explorer bearings contributes to good lubrication of all contact surfaces, even under occa­sional interruptions in lubricant supply.
