You can buy Sealmaster Bearings products like mounted bearings, rod ends and spherical plain bearings at any of your local stores, but if you cannot find your preferred bearing type, you can always shop online.

A plain bearing, identified as a plane bearing as well as a friction bearing may become the simplest kind of bearing, composed of only a bearing surface with no rolling elements. Hence the journal slides on the fag bearing surface. The most basic instance of an plain bearing may be a shaft rotating in a hole. A simple linear bearing is a pair of flat surfaces manufactured to allow motion; e. g., a drawer as well as the slides it rests on or the ways around the bed of a lathe.

spherical plain bearings have an inner ring with a sphered convex outside diameter and an outer ring with a correspondingly sphered but concave inside surface,which enables it to tolerate large load.According to their types and configuration,it can tolerate axle and radial load as well as conbined axle and radial load.Since it has composite material on the outer sphere of the inner ring,thus it can produce self-lubricating during work. Self-lubricating "spherical plain bearings" applies in water conservancy,specialized mechinery and other industries.

Because of the large sphere slidinig contact area and tilt angle of the plain bearing ,as well as most of the spherical plain bearings take special craft treatment,such as surface phosphating, galvanization,chromate treatment,and inlaid mats, spray coating and so on,thus, it has larger load capacity and anti-force capability,as well as anti-corrosion,wear resistant,sel-aligning and self-lubricating features.They can work normally even if it installed mismatch. Therefore,spherical plain bearing are widely used in low-speed swing motion,tilt and rotation movement.

spherical plain bearings are manufactured in a wide variety of materials and are designed to offer bearing solutions in almost any operating environment. SRG koyo Bearings offers a complete line of Spherical Plain Bearings available in inch and metric.
