Deep groove ball bearing:

Deep groove bearing has wide dimension range, which is the mostly type among roller bearing, can carry radial load and certain extent double row axial load.
1, Capped type (with shield or seal)
Could simplify peripheral sealing device of bearing.
Pre-lubricated with an adequate quantity of grease, needn't refilling.
For mainly type and capacity of bearing with shield or sea.

2, With snap ring
Could localize axial by snap ring, simplified the mounting inside case shell.
3, Maximum load type
In structure, standard single row deep groove ball bearing has a siling slot among inn-erring and outer ring, increased ball diameter and the number of ball filled, consequently increase the nominal radial load, but not applicable to carrying axial load or high rate rotary.
Trying fixing the filing slot position of non-rotary ring in the non-carrying load side when mounted.
