What do spherical bushings do?
Spherical bushings work very similarly to rod ends, but the bushings has a much larger surface area than the rod end. In high-power or high-load applications, this increase in surface area spreads the load, giving you an increase in strength. This will also allow the bushing to last longer than a smaller rod end.
Which bearing is used for axial load?
thrust bearings
Axial bearings, or thrust bearings, are designed to withstand force in the same direction as the shaft. This is called an axial load, or thrust load. In some applications, ceramic bearings, a type of radial bearing, are used to withstand high rotational speeds.
Why are bushings spherical?
What are spherical roller bearings used for?
Spherical Roller Bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection and with relatively heavy radial loads and some axial loads in either direction.
What are self-aligning spherical bearings and how do they work?
Self-aligning spherical bearings were first used by James Nasmyth around 1840 to support line shaft bearings in mills and machine shops. For long shafts it was impossible to accurately align bearings, even if the shaft was perfectly straight. Nasmyth used brass bearing shells between hemispherical brass cups to align the bearings to self-align.
How do roller bearings stay in place?
Each roller is loosely retained in place within a cage that goes full circle between the raceways. Figure 1 shows a simplified drawing of a spherical roller bearing on a shaft under deflection.
Can ball bearings support axial loads Besides radial loads?
They can support axial loads in two directions besides radial loads. Ball bearings are used for controlling oscillatory and rotational motion. For example, in electrical motors where the shaft is free to rotate but the motor housing is not, ball bearings are used to connect the shaft to the motor housing.
