Structural Design for Non-Structural Engineers - EIT

Roller support: A roller support allows the rotation of a meer about an axis perpendicular to the plane of the structure, as well as lateral displacement along the support by moving back and forth. It does not, however, allow vertical upward or downward displacement at the support loion and therefore the only possible reaction is a

Tapered Roller Bearings - NACHI

A single-row Tapered roller bearing can support a coined radial and axial load. If either a radial load or bi-directional axial load is to be carried, a pair of bearings must be used in a "face-to-face" or "back-to-back" mounting. Tapered roller bearings are separable into the components: outer ring, inner ring and roller assely.

Angular Contact Ball Bearings - NACHI

The construction of this type ball bearing is similar to the adjacent, BACK-TO-BACK mounting of two Single-row Angular Contact ball bearings. Because fewer balls can be inserted per row compared to Single-row Angular Contact ball bearings, a Double-row Angular Contact ball bearing will have less load capacity than an equivalent size/series BACK-TO-BACK set of …

Tapered roller bearing - Wikipedia

A tapered roller bearing is a unit that consists of both tapered raceways (inner and outer rings), and tapered rollers. The construction is intended for coination loads, such as dual acting axial and radial loads. The bearing axis is where the projected lines of the raceway coine at a common loion to improve rolling, while reducing friction.

Tapered Roller Bearings Matched pairs

Single row tapered roller bearings transmit radial forces from one raceway to the other oblique to the bearing axis. In the case of a shaft supported by two single row tapered roller bearings of identical or different size, the radial load on bearing A leads, due to the inclination of the raceways (0 0°), to an axial load on bearing B.
