Product Description
What is a deep groove ball bearing
Ball bearings are composed of 1 or more rows of balls, placed between 2 coaxial rings. High resistance, they are particularly suitable for high speeds.
That’s why we find them in many mechanical applications. Ball bearings can be with or without seals (water and dust). Ball bearings with integrated seals contain a lubricant that is effective for life. These do not require maintenance.
Our range is also composed of sealed ball bearings with, on both sides, sheet-reinforced acrylonitrile-butadiene rubber (NBR) contact seals. They are supplied ready for assembly and pre-greased.
Deep groove ball bearings are simple in construction as well as easy to operate and maintain. They can run at high speeds and can support both radial and axial loads, furthermore they are robust, versatile and quiet running.

Three basic types of pulleys, their applications and ideal mechanical advantagesThere are 3 basic types of pulleys: movable, fixed and compound. Each has its advantages and disadvantages, and you should be able to judge which type is best for your needs by looking at the table below. Once you have mastered the different types of pulleys, you can choose the right pulley for your next project. Now that you have mastered the 3 basic types, it is time to understand their applications and ideal mechanical advantages. describeThe stress characteristics of a pulley depend on its size and construction. These stresses are derived by comparing the stress characteristics of different pulley designs. Stress criteria include static and fatigue strength analyses and specify maximum stress ranges. Stresses are calculated in a 3D stress field, including radial, tangential and axial stresses. The stress characteristics of pulleys are critical to the design and manufacture of industrial machines. typeA pulley system uses a rope to move the object and 1 side of the rope to lift the load. The load is attached to 1 end of the pulley, while the other end can move freely in space. The force applied to the free end of the rope pulls the load up or down. Because of this, the mechanical advantage of the movable pulley is 2 to one. The greater the force applied to the free end of the rope, the greater the amount of movement achieved. applicationThe applications for pulleys are almost limitless. This simple machine turns complex tasks into simple ones. They consist of a rope or chain wrapped around a wheel or axle. Using ropes, 1 can lift heavy objects without the enormous physical exertion of traditional lifting equipment. Some pulleys are equipped with rollers, which greatly magnifies the lifting force. Ideal mechanical advantageThe ideal mechanical advantage of a pulley system is the result of rope tension. The load is pulled to the center of the pulley, but the force is evenly distributed over the cable. Two pulleys will provide the mechanical advantage of 2 pulleys. The total energy used will remain the same. If multiple pulleys are used, friction between pulleys and pulleys reduces the return of energy. Materials used in manufacturingWhile aluminum and plastic are the most common materials for making pulleys, there are other materials to choose from for your timing pulleys. Despite their different physical properties, they all offer similar benefits. Aluminum is dense and corrosion-resistant, and plastic is lightweight and durable. Stainless steel is resistant to stains and rust, but is expensive to maintain. For this reason, aluminum is a popular choice for heavy duty pulleys. costReplacing a tensioner in a car’s engine can cost anywhere from $90 to $300, depending on the make and model of the car. Cost can also be affected by the complexity of the pulley system and how many pulleys are required. Replacement costs may also increase depending on the severity of the damage. The cost of replacing pulleys also varies from car to car, as different manufacturers use different engines and drivetrains. |
