Retainers keep the balls evenly spaced around the raceway preventing ball to ball contact and thus allowing higher speeds.
Shields, contact seals and non-
Load ratings are expressed in Kgf (kilogramme force)on this website. To keep it simple, we say 1 Kgf = 10 Newtons.
Also referred to as internal radial clearance, it is the amount of play
or looseness between the inner and outer ring.
A number of factors affect speed limitation such as temperature, load, vibration, radial play, retainer, lubricant, ball material and closures.
The ideal fit is where the shaft/housing is the same size as the bore/O.D. of the
bearing which is known as a line-
Tolerances control the dimensional accuracy of a bearing.
This affects the free-
The amount of machining imperfections in the form of uneven surfaces contributes to the amount of bearing vibration and bearing noise.
Correct lubrication is critical to bearing performance. The lubricant will affect most other aspects and ultimately, bearing life.
