Features:
Single row deep groove ball bearings can bear radial and axial loads, and allows very high speed. Deep groove ball bearings can not be split. Deep groove ball bearings can be sealed maintenance-free, and can simplify the structure.
Deep groove ball bearing type:
A dust cover with seals or bearings (expressed as 2RS or ZZ)
2 with a dust cover: single-sided or double-sided iron dust cover. (Expressed as ZZ)
3 with a non-contact rubber seals: single or double-sided non-contact seals. (Expressed as 2LS)
4 with contact rubber seals: single or double contact seals with the inner contact.
N: outer ring with a groove
NR: outer ring with snap ring groove and stop.
Deep groove ball bearings use:
As the deep groove ball bearings self-aligning capability is limited, so need to install the bearing seat concentricity, concentricity bad balance will affect the operation, increase bearing stress, thus shortening the working life of the bearing. Deep groove ball bearings can only allow a small deflection angle, which also depends on the load size.
