Types of Bearings

There certainly are so numerous different varieties. Ball bearings happen to be the most typical type and they are utilized in a wide range of applications. Bearing tools, components and accessories work in a wide range of products made to defend them and produce smooth operation. For instance, gear extractors extract bearings for inspections and repairs, and bearing shields stretch a bearing's life by making sure that the lubricant inside the raceway stays put. Made up of basically a ball and an outside and inside smooth surface for rolling, the ball will carry the load weight, and the force associated is what encourages rotation.


The way the force is placed depends upon if it is a thrust load or radial load. Radial loads put weight on the bearing making it rotate from tension, while axial loads put stress directly on the bearing from an angle. Some bearings even handle both radial and thrust loads. One example is an automobile tire, wherein it supports a radial load on a straight and a thrust load when taking on a corner. There are various different types of bearings all made to handle both types of loads as discussed above. Both load type and capability to support weight come into play when choosing the right bearing for the job.


Here are a number of variations.

Ball Bearings - Ball bearings are the most typical as they take on both radial and thrust loads. The downside is they can only handle small load weights, plus they sometimes warp if they're overloaded. They are available in a lot of merchandise to include a hard disk drive and roller blades among others.

Roller Bearings - Roller bearings are made to carry heavy loads. The main roller is cylindrical and the load is distributed over a bigger area making it simpler for the bearing from taking on huge amounts of weight. Radial loads are ideal for roller bearings, but thrust loads aren't, sometimes a needle bearing is used if there is not sufficient space.


Ball Thrust - Low weight and low-speed thrust loads are better managed by ball thrust bearings. Ball thrust bearings are utilized in bar feces to support the seat better, this is just an example of how they're used.

Roller Thrust - The roller thrust bearings are much like ball thrust. The amount of weight handled by the bearing is where the difference lies, and roller thrusts are found in car transmissions to support helical gears.

Tapered Roller Bearings - Tapered roller bearings are made to take on big thrust and radial loads. The versatility of those bearings makes them ideal for vehicle hubs as they may carry both types of loads at a very high weight.
