Barrel - Provides assistance to high radial socks loads that cause misalignment and uses its shape and size for compensation. [7] Needle - Varying in size, diameters, and materials these types of bearings are best suited for helping reduce weight as well as smaller cross sections application, typically higher load capacity than ball bearings ...
A needle roller bearing. A needle roller bearing is a special type of roller bearing which uses long, thin cylindrical rollers resembling needles. Ordinary roller bearings' rollers are only slightly longer than their diameter, but needle bearings typically have rollers that are at least four times longer than their diameter. [1]
In such instruments, jewel bearings are often used as pivots for their needles which need to move reliably and with low variability even when measuring small changes. Bearing bores are typically smaller than 1 mm and support loads weighing less than 1 gram, although they are made as large as 10 mm and may support loads up to about 500 g. [3]
A rolling element bearing's static load rating is defined to avoid this failure type. Increasing the number of elements can provide better distribution of the load, so bearings intended for a large load may have many balls, or use needles instead. This decreases the chances of brinelling, but increases friction and other factors.
In the case of ball bearings, the bearing has inner and outer races and a set of balls. Each race is a ring with a groove where the balls rest. The groove is usually shaped so the ball is a slightly loose fit in the groove. Thus, in principle, the ball contacts each race at a single point.
In 2003 Torrington was purchased by the Timken Company, nearly doubling its size. [4] Timken ceased all operations in Torrington and shut down the plants in 2006. [5] Timken also redistributed employees to their other plants. [2] The rest of the heavy bearing plants and needle bearing plants were eventually sold to JTEKT in 2009.
