Roller bearings are the earliest known type of rolling-element-bearing, dating back to at least 40 BC. Common roller bearings use cylinders of slightly greater length than diameter. Roller bearings typically have higher radial load capacity than ball bearings, but a

» Lubrication of bearings at low temperatures

Nov 16, 2000  Bearing friction is related to the shear stresses that occur in the lubricant during rotation. These stresses will not be the same in a small ball bearing as in a large spherical roller bearing. Consequently, this test is also not reliable on its own for the assessment of low-temperature lubrication.
