Export Water pump bearing

الوصف

The WN-S bearing design features standard “WN” family characteristics with a shaft reduction on the impeller end. Some designs offer shaft reductions on both ends. A WS bearing consists of a ball / ball internal design. The “S” represents a special design and is associated with any ball / ball bearing that does not offer standard outer ring or shaft dimensions. A WNS bearing consists of a ball / roller internal design. This bearing utilizes a roller complement for increased radial load carrying ability. The “S” represents a special design and is associated with any ball / roller bearing that does not offer standard outer ring or shaft dimensions. Orientation of ball raceway and roller raceway may vary. The WK bearing is essentially a “king size” W bearing that features a ball / ball internal design. Standard dimensions consist of a 1.***0" outer ring diameter and a 2.**5" outer ring length. The standard shaft diameter size is 3/4". Larger rolling elements and envelope dimensions allow for higher load carrying ability. This bearing is typically used in automotive water pump applications. Some special designs are available that allow this bearing family to be used in many other applications.
