The diverse demands in the engineering field have led to the introduction of highly sophisticated mechanical components like the spherical plain bearing. The self-aligning feature and multi-directional movements of the bearing help in various applications in the industries like automobile, aviation, construction, transportation, farming equipment, and so on.
The standardized designs of the spherical plain bearing have hardened carbon chromium steel, which undergoes phosphate and Molybdenum Disulfide treatment to reduce friction. This bearing offers provision for re-lubrication through the grooves or holes provided in the outer races. Further developments in its design have resulted in using PTFE lined rings to help self lubrication so that its use in the machines requires no maintenance.
The stainless construction also helps avoid the corrosion of the parts of the bearing and provides high efficiency and low friction in various applications.
Many Uses of Spherical Plain Bearings
The unique features of spherical plain bearings have made it the most important component in the heavy industrial applications. To get to know the distinctive characteristics of spherical plain bearings, it is important to know their uses. The following are the primary uses of this bearing in various applications.
The bearing with its inherent design can accommodate varying degree of misalignment in the shafts and rods
It is designed to support heavy radial loads that it provides consistency in performance. This feature makes the spherical plain bearings best suitable in construction, power, railway and oil industries.
The marginal lubrication is the principal attraction that has lead to the wide application of this plain bearing in various industrial places. The design supports re-lubrication and self-lubrication with grooves in the races and PTFE coatings in the cylindrical housing respectively for maintenance-free long running of the machines.
The spherical plain bearing in the heavy-duty industries permit axial loading for it has spherical rollers. It also allows relative misalignment between the unit and shaft.
Applications of Spherical Plain Bearings
Like angular contact ball bearings, the spherical plain bearings are known for heavy radial support load. However, the latter’s applications are wide due to its adaptability to high alternating, as well as shock loads. The bearing pillow block in this field is another development as it offers durability, high performance and easy installation. Some of the industries using the spherical plain bearing are gear drives, oil exploration, railway, wind turbines, railway engineering, construction, power generation and rolling mills.
