When it comes to reliable performance, there are a few types of bearings that can accommodate heavy loads with varying misalignments in extreme conditions. Spherical plain bearings are one among them and they are known for minimum maintenance, long life and high reliability. The bearings are crafted to handle high radial loads and perform consistently under harsh conditions of critical application stress and reduced lubrication.

When it comes to usage in applications, spherical plain bearings, with cylindrical rolling elements, sphered ring raceways and a cage are used. The spherical plain bearing with rod ends is the other choice. Nevertheless, these bearings are available in various dimensions, designs, sizes and series. There are large bearings and small ones that are maintenance-free. They are suitable for heavy-duty applications for the sphered rollers allow axial loading, as well as angular misalignment.
Some of the characteristics of this state-of-the-art and ready-to-mount bearing are:
Simple maintenance: The sliding contact surfaces are made of carbon chromium steel, which are treated with phosphate and special lubricant. This makes it suitable for applications in areas that require handling of high static loads and alternating loads, and high-frequency alignment.
Better service life: Where there is heavy direction load, the spherical plain bearing has to do minor alignment movements. This may cause lubricant starvation in the bearing. With the multi-groove system, the bearing ensures better lubricant supply to the loaded zone, allows extended re-lubrication intervals and extends the lubricant reservoir.
High operational reliability: The spherical plain bearing is made of stainless steel and it comes with seal or without seal. The sealed ones are designed to have lip seal integral with the outer ring face to prevent the sliding contact surfaces from getting contaminated in extreme or normal environments.
Exhaustive range:When it comes to normal requirements, the bearing comes in a wide range of sixes and designs. Starting with a 4 mm bore, there are numerous types to suit any application.
Typical Uses of Spherical Plain Bearings in Applications
The variations in design, sizes and dimensions of a spherical plain bearing makes it suitable for a wide range of applications. There are some used for heavy applications in industry and they are maintenance free. Some of the popular types of spherical plain bearings are the radial spherical plain bearing, spherical plain thrust bearing, and angular contact spherical plain bearing, which is same as the angular contact ball bearings in managing axial and radial loads.
The bearing is also available in improvised versions, with a bearing pillow block and rod ends. This helps easy maintenance, high reliability and long service life. These improved variants of a spherical plain bearing do not influence any deformations and therefore, give minimal edge stresses to the adjacent components.
