In an internal engineering study, Nyloil bushings and C93200 Bronze bushings were used together to test the effect of: PV limits of the bushing. As mentioned previously, bushings are typically used for heavier loads at slower speeds. This is evident in the diagram as neither bushing is capable of handling significant loads at high speeds. The faster the speed, the lower its load capacity. P-max (psi) and V-max (fpm) values are provided by the manufacturer for each product. P-max is the maximum load at 0 rpm and V-max is the maximum speed at light load (maximum shaft rpm). For practical applications, compare the calculated P, V, and PV values to the maximum tolerances to determine if the bushing will operate. Ensure that the bushing operates within a range below the limiting PV curve.

Graphite bushings are used in many applications due to their unique mechanical and physical properties.

Sleeve bearings are not designed for high speeds, with studies showing their top speed is around 5,000 RPM. This limitation can cause a number of problems in applications that require higher speeds, such as motors and fans. Another problem with sleeve bearings is that they tend to have a limited life expectancy when used in heavy-duty applications such as large industrial machines. Their design also makes them unsuitable for radial loads as they easily deform under pressure. Over time, the amount of dirt that gets into the sleeve bearings increases, which can lead to premature failure.

Bushing – often called a sleeve bearing, is a cylindrical bearing used to support the load on an operating shaft that slides back and forth between moving surfaces. Bushings are special bearings that can be made from a variety of materials and slide on a rod or shaft, providing extremely low friction movement, excellent shock absorption, and minimizing energy consumption, noise and wear while providing an effective seal , protected from dust and moisture. . Fortunately, bushings are self-lubricating, making them ideal for low- or maintenance-free operation. Self-lubrication is achieved through a uniform pattern of dimples on the bushing surface, which act as grease reservoirs. Regardless of the type or size of sleeve bearings used, they have an advantage over traditional ball or roller bearings due to their lower coefficient of friction due to their minimal contact area. This makes bushings ideal for applications where speed, accuracy and durability are critical. With these benefits in mind, it’s easy to see why sleeve bearings are so popular in many industries today. Bushings are widely used in automobiles, white goods, drilling tools, motors, hydraulic external gear pumps, etc. In the automotive industry, for example, sleeve bearings provide rotary linear motion in hinges, seat adjustment systems and steering wheels. Some nylon bushings can operate without the use of lubricants and are particularly suitable for the food and textile industries where dry applications are preferred.
