  2. Rolling-element bearing - Wikipedia

    en.wikipedia.org/wiki/Rolling-element_bearing

    A cylindrical roller bearing. 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 a higher radial load capacity than ball bearings, but a lower capacity and higher friction under axial ...

  3. Linear-motion bearing - Wikipedia

    en.wikipedia.org/wiki/Linear-motion_bearing

    A linear-motion bearing or linear slide is a bearing designed to provide free motion in one direction. There are many different types of linear motion bearings.. Motorized linear slides such as machine slides, X-Y tables, roller tables and some dovetail slides are bearings moved by drive mechanisms.

  4. Needle roller bearing - Wikipedia

    en.wikipedia.org/wiki/Needle_roller_bearing

    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]

  5. Tapered roller bearing - Wikipedia

    en.wikipedia.org/wiki/Tapered_roller_bearing

    The bearing was composed of two sets of cylindrical rollers, one set larger in diameter than the other, that fit on flats machined on the tapered axle-skein. In 1898, Henry Timken was awarded a patent [2] for the tapered roller bearing which used conical rollers. At the time, Timken was a carriage-maker in St. Louis and held three patents for ...

  6. Spherical roller bearing - Wikipedia

    en.wikipedia.org/wiki/Spherical_roller_bearing

    Spherical roller bearing with a brass cage in a cut-through view. A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring.

  7. Lewis Heim - Wikipedia

    These bearings contained a full complement of balls or rollers that made the bearing suitable for higher load ratings as well as extending its operating life. Many of Heim's machines and methods developed in the 1950s and 1960s continue to be employed in the manufacture of modern rolling bearings.
