How to choose the right bearing

Запчасти

Any bearing, regardless of design and purpose, must be lubricated for normal operation. Its absence leads to increased friction, overheating and failure of the unit.

How to choose the right bearing

The assortment of this group of goods is so large that even an experienced specialist can get lost in its diversity. After all, it is necessary not only to determine the design features of the part, but also to take into account the physical, landing dimensions. The larger the selection of bearings https://podshipnik-market.com.ua/shop/, the easier it is to find the best one to replace a worn out part. But, here, too, several important factors must be taken into account.

Most important criteria

If we take all types of bearings, they can be conditionally divided into several groups. This will not only facilitate future searches, but will also improve the reliability of the assembly by choosing a better product. The main groups are:

  1. Self-aligning form, or classic.
  2. Designed for radial, thrust or angular contact loads.
  3. One or more rows of rolling elements.
  4. Balls or rollers are used for rolling.

The ball type bearing is the simplest, but at the same time it is capable of withstanding significant loads, subject to the right choice. Roller analogs are more expensive and are used in mechanisms with particularly heavy physical loads on the mechanism.

Types of tested loads

The key selection factor is the load that the bearing must take on. If you make a mistake in this, the part will fail almost immediately, since the bearing will simply collapse under the action of an unusual load for it. The following types are available for selection:

  • rollers or needles take on radial loads, correctly distributing it over a large area;
  • axial load is assumed on balls or radial thrust rollers;
  • the combined load, the most difficult, is usually used on the wheels of the car.

Any bearing, regardless of design and purpose, must be lubricated for normal operation. Its absence leads to increased friction, overheating and failure of the unit. The availability of quality lubricant in the right amount significantly extends the life of the balls, rollers and grooves in which they slide. Fully enclosed bearings already have a lifetime lubrication requirement for normal operation.
