The article presents information on the identification of the best plain bearing. Topics include the use of sleeve-type bearings in rotating or sliding shaft applications, the need to consider factors during the selection such as contamination, operating temperatures, and chemical use, and an understanding of the pressure multiplied by the speed of operation (pV) value.

Reports miniature and instrument-sized ball bearings excel in jobs needing predictable levels of torque, runout and stiffness. Reason bearing makers typically package the units in Class 100 clean rooms after final inspection; Most common cause of raceway damage in miniature bearings; Three basic preload methods needed by bearings to remove axial play and boost axial and radial stiffness. INSET: PRESS FIT DO'S AND DON'TS.

The article presents a comparison of bearings including products from SKF US Inc., Kaydan Bearings Division, Igus Inc., Graphite Metallizing Corp., Stafford Manuacturing Corp. and GGB North America LLC.

The article features the self-lubricating rod end bearings from J.W. Winco Inc. The bearings are in threaded-stem or tapped type metric sizes control and link mechanisms in high-load, low-speed applications with hanging angles. The body of the bearings is made of zinc-plated steel with ball socket of hardened and ground bearing steel.
