3) Deep-groove bearings have higher load ratings for their size than shallow-groove , but are also less tolerant of misalignment of the inner and outer races.
4) A misaligned shallow-groove bearing may support a larger load than the same sized deep-groove bearing with similar misalignment.
5) This kind of bearing is also available both in open design and sealed design.
6) The seals way of the bearing: RS: contact seal on one side of the bearing
2RS: contact seals on both sides of the bearing
Z: shield on one side of the bearing
ZZ(2Z): shields on both sides of the bearing.
7)special processing on the surface or with rubber covers to proofing water,proofing dust and with good sealing.(RS,2RS)
8) Bearing with -RS seals has better sealing but lower limited speed compared with the bearing with –Z seals.
9)special processing on the surface or with iron covers to proofing dust and with good sealing.(ZZ).
