608zz 608 2rs Ball Bearing With GCr15

Advantages of Deep Groove Ball Bearing:

• Sustain radial, axial, or composite loads.
• Provide both high-running accuracy & high-speed operation
• Can replace high speed angular contact ball bearings
• Simple design
• Maintenance free
• Longer service life

• Small and mid. size bearings are  available in a variety of shield, seal and snap ring arrangements. Big ones normally are fitted with solid brass or steel cages.

ball bearing 608

Deep groove ball bearing 608 bearing is smaller bearing.Its structure is simple, it consists of inner and outer rings with deep symmetrical ball race, separator and complement of balls, and it can be easy to operate.It is mainly used for standing the radial load. But when the radial play is increasing, it has the performance of angular contact bearing assembly. In that case, it may simultaneously stand the radial loads and the axial loads.In some cases, which are not suitable to using spherical roller thrust bearing and the rotational speed is rather high. It can also be used to stand purely axial loads.Compared with other kind of bearings with the same size, this kind of bearing enjoys smaller coefficient of friction and higher limits speed. But they cannot

bear impact. Therefore, it is not suitable to bear heavy load.

How a 608 Bearing Functions

In a 608 bearing, the bearing balls rotate between two rings – an inner ring and outer ring – and are kept apart by a metallic crown type "H" or a two piece metallic ribbon type "R" cage which are interchangeable in most common applications. The entire unit is sealed with a rubber or metal shield. This shield is helpful in reducing the entry of particulate contaminants into the bearing and also reduces the amount of lubricant leakage. Bearings are usually appended with letters like S, Z, SS, or ZZ to indicate that they are sealed, shielded, or double shielded bearings. In fact, just by looking at the part number of a 608 ball bearing, you can tell what type it is. 608 ball bearings from NMB Tech are pre-lubricated either with oil or grease to make them less susceptible to corrosion or bearing failure, and to allow them to withstand high temperatures.
