Basic load rating(Cr, C0r) ƒ0 factor is obtained.
This design provides high load rating, uniform wear behavior, low friction and extended service life.
Basic dynamic load rating(Cr) is obtained from the bearing specification table.
From equation(1), the basic dynamic load rating is obtained as follows.
If the TOB linear bushing is used will two ball circuits loaded uniformly, the load rating will be greater.
We primarily produce derrick equipment with a 25 ton or 30 ton load rating, but also have experience manufacturing heavy derricks with a 100 ton load rating.
The basic dynamic load rating of the linear bushing is 882N from the dimension table.
Its perfomance and characteristics are similar to CA, but load rating is lower.
Furniture dolly features a solid wood construction and has a load rating of 1,000 lbs.
Since dimension stabilizing treatment diminishes material hardness, the basic dynamic load rating may be reduced for some types of bearings.
The lift(L) of a linear bushing can be obtained from the following equation with the basic dynamic load rating and the load applied to the bush.
One concern is that the load rating is slightly low for UK roads, going forward if possible we would like to have it slightly higher.
Through this, it was possible to improve dynamic load rating by 10%, static load rating by 30% and life by around 1.3 times that of a conventional bearing.
D: Motor load rating: Normally the derating is 20% of the rated load, and it needs to adopt a circuit that suppresses the impulse current and the arc is also required.
The basic static load rating is the static load which responds to the calculated contact stress shown below, at the contact center between the raceway and rolling elements which receive the maximum load. .
JTEKT has attained bearing longevity by increasing load rating and improving bearing material cleanliness through optimal internal design(maximum design), in order to better respond to the tough application conditions of spherical roller bearings.
Note: Although the special 2”(50mm) cross rod spacing does allow for less open space on the grating surface, it does not affect the load rating of the grating.
In high temperature operation, bearing material hardness deteriorates, as material compositions are altered. As a result, the basic dynamic load rating is diminished.
Accordingly, where the dynamic equivalent load is P, and rotational speed is n, equation(5-4) can be used to calculate the basic dynamic load rating C; the bearing size most suitable for a specified purpose can then be selected, referring to the bearing specification table.
Load rating(60Hz).
