DEEP GROOVE BALL BEARING

タイトルまたは説明

Deep groove ball bearings are mainly used to withstand radial loads, but also commonly used to withstand radial and axial composite loads。Especially when the speed of mechanical equipment is very high, not suitable to use thrust bearing, the bearing can be used to withstand two-way pure axial load, and during the work without maintenance, is a low price, a wide range of uses of a bearing.Deep groove ball bearing model is: deep groove ball bearing (****0 type); Deep groove ball bearing with stop groove in the outer ring (****0N); One side with a dust cover, Deep groove ball bearing with stop groove on the other outer ring (*****-ZN); Dust cover on both sides, Deep groove ball bearing with stop groove in the outer ring (******2 ZN type); Deep groove ball bearing with dust cover (****0Z); Deep groove ball bearing with dust cover on both sides (******2Z); Deep groove ball bearing with sealing ring (*****-LS, *****-RZ); Deep groove ball bearing with sealing ring on both sides (******2LS, ******2 RZ); Deep groove ball bearing of flange outer ring (type F****0); Deep groove ball bearing with outer flange with dust cover (F*****-Z); There are *1 kinds of deep groove ball bearings (F******2Z) with dust cover on both sides.[2]According to the size of the deep groove ball bearing, it can be divided into:
(1) Micro bearing- - - -nominal outer diameter size range of less than *6mm;
(2) Small bearings- - - -nominal outer diameter size range of ****5mm;
(3) Small and medium-sized bearings- - - -nominal outer diameter size range of *****5mm bearings;
(4) Medium and large bearings- - - -nominal outer diameter size range of ******0mm bearings
(5) Large bearings- - - -nominal outer diameter size range of ******0mm bearings;
(6) Super large bearing- - - -bearing with nominal outer diameter size range of more than **0mm.
