217 Bearing Structural Features & Performance Benefits
The performance of the 217 bearing is defined by its robust construction and material selection. The single row design with deep raceways provides excellent radial load capacity, with a dynamic rating of 21,762 lbf and a static rating of 22,481 lbf. The use of a Nylon cage reduces friction and weight, contributing to the high limiting speed and smooth operation. The chrome steel rings and balls ensure high wear resistance and long service life under standard operating temperatures ranging from -30°C to 120°C. The open design allows for versatile lubrication options to suit specific application needs.
