Features of Deep groove ball bearings NTN 60-67-68-69-62-63-63-64-160 series (contains model 6904ZZNCM)
Deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread. In addition to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, snap rings are sometimes used on the periphery. As to cages, pressed steel ones are the most common. For big deep groove ball bearings, machined brass cages are used. Machined cages are also used for high speed applications.
Application: Like with other types of bearings, deep groove ball bearings are used in a wide variety of different industrial machines, including gearboxes, industrial instruments, motors, pumps, internal combustion engines, agricultural machinery, construction equipment, and engineering machinery. Deep groove ball bearings are especially critical to the operation of electrical motors.
