Product Description

Specification of 61902-2rs/61902Z deep groove ball bearing

Deep Groove ball bearings are the most popular of all the ball bearing types because they are available in a wide variety of seal, shield and snap-ring arrangements.The bearing ring grooves are circular arcs made slightly larger than the radius of the ball.

The balls make point contact with the raceways (elliptical contact when loaded). The inner ring shoulders are of equal height (as the outer ring shoulders). Deep Groove ball bearings can sustain radial, axial, or composite loads and because of simple design, this bearing type can be produced to provide both high-running accuracy and high-speed operation. Standard ball retainers (cages) are made from pressed steel. Machined cages are used in bearing operation at very high speed or for large diameter bearings.

Bearing characteristics of deep groove ball bearing 61902-2rs/61902Z

Single row deep groove ball bearings are the most widely used roller bearing type in the world due to their versatility

and overall performance. They are characterized by having deep raceway grooves in which the inner and outer rings

have circular arcs of slightly larger radius than that of the balls. They also have non-separable rings. Their straight forward basic

design has many advantages:

Excellent for high speeds
Good radial load capacity
Acceptable axial load capacity in both directions
Have low torque capacity at startup and running speeds
Can operate with low noise
Require little maintenance

As flexible as the performance is, the configurations of single row ball bearing is also as versatile. 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 outside edge. While many different retainers are available,

pressed steel cages are most commonly used. Even tapered bores are available upon special order.

Series representing the size and load capacity of each. They are:

6000 Series - Extra Light Ball Bearings – Ideal for limited space applications
6200 Series - Light Series Ball Bearings – Balanced between space and load capacity
6300 Series - Medium Series Ball Bearings – Ideal for heavier load capacity applications

Deep groove ball bearings are the simplest yet the most popular bearing:

Suitable for very high rotating speeds
Well suited for medium high radial and axial loads in one or both directions
Various seals and grease variants available for different operating conditions
Numerous clearance and tolerance classes available for different operating conditions

Series: 600, 6000, 6200, 6300, 6400, 1600;

Application examples: electrical motors, general machinery, industrial gearboxes, pumps, agricultural machinery, et
