Fafnir Radial Bearing Thrust Capacity
Fafnir Radial Bearing Thrust Capacity
(OP)
I'm having trouble locating the thrust load capacity of a Fafnir 204 radial bearing. I've spoken with a couple people at Timken, and am getting tossed around a little.
Is there a convention similar to some rod-ends, where the thrust or axial load capacity is 20% of the radial capacity?

RE: Fafnir Radial Bearing Thrust Capacity
Then there is the thrust load that causes a problem because it moves the contact ellipse too far up the race. That depends on clearance, etc, but is usually between .4 and .5 for ball bearings under 60 mm bore

this application? Did Timken buy Fafnir?
There should still be some Fafnir Catalogues
about and you might be able to get the
Static and Dynamic Capacities from it.
Often Radial bearings have little thrust
capacity.

contact angle of the balls in the raceway
and is a sine function of that angle.
Divide by approx 1.25 which assumes only a
80 percent of the balls are carrying the load.
The radial capacity is dependent on the
contact angle of the balls in the raceway
and is a cosine function of that angle.
Divide by 4.37 which assumes only a 25 percent
of the balls carry the load.
I would assume the contact angle to be approx
15 degrees or less for a radial bearing.
These are rough guidelines
