Radial Ball Bearing Both Sides Rubber Sealed 6004-2RS

Basic Info

Model No.: 6004-2RS

Product Description


6004-2RS Ball Bearing 20x42x12mm Sealed Single Row Radial Ball Bearing, Both Sides Rubber Sealed: Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearingsS are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.



Single row deep groove ball bearings are used in a wide variety of applications, they are simple in design, non-separable, suitable for high speeds and are robust in operation, and need little maintenance. Deep raceway grooves and the close conformity between the raceway grooves and the balls enable deep groove ball bearings to accommodate axial loads in both directions, in addition to radial loads.


RSH or RS = Sheet steel reinforced contact seal of acrylonitrile-butadiene rubber (NBR) on one side of the bearing
2RSH or 2RS = RSH or RS contact seal on both sides of the bearing
RSL = Sheet steel reinforced low-friction contact seal of acrylonitrile-butadiene rubber (NBR) on one side of the bearing
2RSL = RSL low friction contact seal on both sides of the bearing
Z = Shield of pressed sheet steel on one side of the bearing

2Z or ZZ = Z-Shield on both sides of the bearing



Single row deep groove ball bearings are manufactured as open type (unsealed), sealed and shielded, the most popular sizes of deep groove ball bearings are also produced in sealed versions with shields or contact seals on one or both sides, the bearings with shields or seals on both sides are lubricated for life and are maintenance free. A sealed bearings seals has contact on the bearings inner and outer, a shielded bearings shield has contact on the outer only, and Shielded bearings are primarily intended for applications where the inner ring rotates. If the outer ring rotates, there is a risk that the grease will leak from the bearing at high speeds.
