deep groove ball bearings Thrust ball bearings are more advantages.

Deep groove ball bearings are bearing the most common type. Basic deep groove ball bearings have an outer ring, an inner ring, a set of balls and a group holding structure into. Deep groove ball bearing type code 6.
Deep groove ball bearings are mainly used for pure radial load, but also to support radial load and axial load. When the only pure radial load, the contact angle is zero. When the deep groove ball bearings with a larger radial clearance, ie performance with angular contact bearings can bear large axial load. Deep groove ball bearing friction coefficient is small, limit speed is also high, especially in very high speed axial loading conditions, deep groove ball bearings Thrust ball bearings are more advantages.
Deep groove ball bearing structure is simple, easy to reach compared with other types of high manufacturing precision, so easily into a series of mass production, lower manufacturing costs, the use of extremely common. In addition to basic type deep groove ball bearings, there are a variety of structural variants, such as: Shielded deep groove ball bearings; with rubber ring of deep groove ball bearings; a groove deep groove ball bearings; has loaded ball gap large load capacity of deep groove ball bearings; Double row deep groove ball bearings.
 deep groove ball bearings with dust cover
Standard deep groove ball Precision bearing  ith dust cover and Z-2Z-two, one side with a dust cover is Z-shaped, both sides with a dust cover is 2Z type.
Shielded bearings lubricated with more difficult in a separate, placement lubricating oil and inspection inconvenient conditions, bearing the manufacturer has been filling the quantitative, grades rust, dual lithium grease lubrication. Each bearing grease injected amount of available space inside the bearing is usually 1/4 to 1/3, can also be used according to user requirements increase or decrease the amount of fat. Usually injected grease in the bearing operating conditions -40 ~ +120 ℃ operating. If there is a higher demand for bearings, but also filling other performance under the circumstances, grades of grease. Shielded bearings through the grease can be effective long-term work, without re-grease during use.
Shielded bearings are used for small and medium sized generators, motor rotor ends, cars, tractors, air conditioners, fans, etc., as well as noise and vibration of the bearing with special requirements of the occasion.
