SKF radial spherical plain bearings are a type of bearing specially designed to bear radial loads and combined radial and axial loads. This type of bearing has excellent misalignment compensation capabilities and can maintain good working performance even in the case of installation errors or shaft bending. SKF’s radial spherical plain bearings usually use steel-on-steel or other material combinations of sliding contact surfaces to meet the needs of different working conditions
Design features and technical advantages Material selection and surface treatment: SKF’s radial spherical plain bearings choose different material combinations according to specific application scenarios. For example, some models use SKF Explorer steel-on-steel sliding contact surface combination. This material not only improves the dynamic load-bearing capacity of the bearing, but also reduces friction and extends service life through special surface treatment
Seal design: In order to protect the internal structure from the intrusion of contaminants, SKF’s radial spherical plain bearings are equipped with a variety of types of sealing devices. For example, some models have three-lip heavy-duty contact seals on both sides, which can effectively prevent dust and moisture from entering the bearing while allowing lubricant to be replenished.
Lubrication method: SKF radial spherical plain bearings can be lubricated through lubrication holes and annular grooves, which is convenient for maintenance and maintenance.
Application scenarios SKF radial spherical plain bearings are widely used in various occasions that need to withstand heavy loads and complex working conditions, such as metallurgical equipment, heavy machinery, railway vehicles, etc. These bearings can operate stably in high temperatures and harsh environments, and have the characteristics of long life and low maintenance requirements.
SKF Radial Spherical Plain Bearings are high-performance, self-aligning components engineered to manage radial loads while accommodating misalignment between shafts and housings. Featuring a spherical inner ring and a convex outer ring, these bearings enable smooth rotational and oscillating movements in applications subjected to heavy loads, vibrations, or harsh environmental conditions. Designed for durability and minimal maintenance, SKF’s radial spherical plain bearings are widely used in industries such as construction, agriculture, mining, and renewable energy, where reliability and adaptability are paramount.
