Light Double Row Angular Contact Steel Shielded Ball Bearings

The 5200 series has a smaller cross section than the 5300 series, making it suitable for smaller spaces, lighter loads, and higher speeds.

  • Double row angular contact ball bearings provide the function of a pair of single row angular contact ball bearings arranged back-to-back but require less space. They also provide very stiff, rigid bearing arrangements.
  • Low-alloy, through-hardened carbon chromium steel for durability and resistance to deformity under heavy loads.
  • Suitable for supporting tilting moments the 20-degree contact angle of the balls in relation to the raceways gives the bearing a greater capacity for supporting thrust loads over bearings with a standard contact angle of zero degrees.
  • Used in blower motors, high speed pumps, motorcycle, transmissions and many other industrial applications.
  • Double Row Angular Contact ball bearings may offer some economic benefits as well as handling and mounting benefits versus pairs of Single Row Angular Contact ball bearings; however, they may offer less design flexibility and performance in some cases.
  • The bearing has a shield on both sides to reduce contaminants and lubricant leakage.
