After the deep groove ball is loaded on the shaft, the axial displacement of the two targets of the shaft or outer casing can be restricted to the axial overlapping boundary line of the bearing, so that the axial direction can be positioned in the two direction. The rest, this type of bearing also has a positive calorie strength that is still working properly when the outer casing hole is skewer 2 '~ 10', but there is affirmative effect on the bond life. The deep groove ball bearing suction is mostly a steel plate stamping ribber, and a large-scale bearing is used to use a vehicle metal solid holder.
