Cylindrical roller bearings are available in two different designs-

• Sealed
• Split

In sealed bearings, the rollers are protected from contaminants, water and dust, and provides lubricant retention and contaminant exclusion. This results in lower friction and longer service life. On the other hand, split bearings are intended primarily for bearing arrangements which are difficult to access, example can be crank shafts, where they simplify the maintenance process and replacements.
