Plain Bearings
A plain bearing, also known as a plane bearing or a friction bearing is the simplest type of bearing, comprising just a bearing surface and no rolling elements. Therefore the journal (i.e., the part of the shaft in contact with the bearing) slides over the bearing surface. The simplest example of a plain bearing is a shaft rotating in a hole. A simple linear bearing can be a pair of flat surfaces designed to allow motion; e.g., a drawer and the slides it rests on[3] or the ways on the bed of a athe.
Plain bearings, in general, are the least expensive type of bearing. They are also compact and lightweight, and they have a high load-carrying capacity.Welcome to SANBURG BEARING INT'L LTD for Spherical Plain Bearings. RBC has been a pioneer in spherical bearing technology since inventing the fractured outer race design over 20 years ago.
Since that time, SRG has continued to introduce industry leading innovations such as high misalignment, angular contact, extended inner ring, tapered bore, case carburized, and enhanced lubrication groove spherical bearing designs. These advanced products are used in pivoting, high load bearing applications where angular misalignment is required. Most typically, SRG spherical plain bearings are employed in hydraulic cylinder rod ends, vehicle steering linkage suspensions, heavy equipment articulated joints, and other severe duty uses.
