What are pulleys bearings?

The

Pulley bearings are located in the center of the Kladic wheels used in a given pulley mechanism. Usually the pulley bearing is cast or forged from heat -resistant metal or metal alloys. Depending on the specific bearing type, it usually looks like a metal ring or a set of rings built into the center of the pulley. Inside the bearing, inner and outer tracks, balls, lubricating oil and other components to turn the pulley. In the case of ball bearings, each ball rotates inside the pulley and acts as dozens of small fingers to turn into a pulley, distribute load weight and absorb heat.

Since the pulley wheels need the ability to turn full 360 degrees, most of the wheels are mounted in the center. Medium mounting gives the pulley wheels a total shape similar to a donut, with a central opening mounted on the axle. A metal bearing is inserted around the center mounting opening, usually pushed in a place when the wheels are Manufaktured. The purpose of the bearing of the pulley JE protect the mounting structure and the wheel from the heat, allow increased speed and ensure smooth operation. Some types of pulley bearings also reduce fluctuations and vibrations, forcing the pulley wheels to turn on the level, even the axis.

Regardless of the specific design, materials or type of bearing used, the bearing of the pulleys allow smooth and continuous rotation of the pulleys and at the same time reduce the resistance and heat by friction. Types of pulley bearings differ depending on the type of pulley wheel used. The most commonly used ball bearings mechanisms, a number of small, heavily oiled metal balls set in the metal track. As the pulley wheels turn, the individual balls inside the bearing help evenly spread the load weight, reduce friction and provide smooth, even rotation with limited vibration or speed loss.

pulleys made of plastic, nylon and other synthetic polymERs are most often incorporated by the pulp bearings. Since the wheel itself is made of plastic, the heat of friction caused by rotation can easily the curriculum, melt or otherwise shorten the life of the pulley. When mounted a wheel with pulley bearings around the mounting hole, each wheel is able to handle heavier loads at higher speeds without causing damage to plastic or other polymer. Instead of the plastic wheel bearing the weight and heat of a particular load, it absorbs most of the voltage and heat and ensures that the wheel maintains its shape and power.
