Product Features of YSA 210-2FK Bearings

  • Quick and easy mounting
    Different locking methods allow quick and easy mounting of the housing bearing onto the shaft.
  • Adapting to initial misalignment
    Spherical outer surface can be initially misaligned by tilting in the housing
  • Service life
    Long The different sealing solutions available offer a long service life for a variety of applications with high contamination levels.
  • Reduced noise and vibration levels
    Where high noise and vibration levels are required, SKF can provide suitable shaft locking methods.

Applications of YSA 210-2FK Bearings

Insert bearings (SKF Y-bearings) are based on sealed deep groove ball bearings in the 62 and 63 series, but have a convex outer ring and in most cases an extended inner ring with a specific locking device, enabling quick and easy mounting onto the shaft.The following are examples of applications where insert bearings may be used:

  • Agriculture
  • Food and beverage processing and packaging
  • Air handling

FAQ of YSA 210-2FK Bearings

  • Generally speaking, insert bearings are standard radial bearings that fit into the housing. Although they are usually sold with the housing, these bearings can also be purchased as a stand-alone product to be used as a replacement. While standard radial ball bearings must be pressed into a machined shaft, with special mounting tools, insert bearings can be fitted directly to the shaft with a sliding fit. However, insert bearings are usually mounted on shafts with bores slightly smaller than the bore diameter of the bearing. This loose fit requires a locking device to hold the bearing firmly in place. The inner ring of the bearing extends to one side to accommodate the locking device. In addition, the width of the inner ring of a housing bearing may vary depending on the type of bearing.

Loads are defined by their direction. Loads perpendicular to the shaft are called radial loads and loads parallel to the shaft are called axial (thrust) loads.

DGBB can carry axial loads in both directions, whereas angular contact ball bearings can only carry axial loads in one direction.
