One-way bearing combining sprags and bearing rollers in one race Sprags jam when driven and slide when in reverse. A sprag clutch is a one-way freewheel clutch.It resembles a roller bearing but, instead of cylindrical rollers, non-revolving asymmetric figure-eight shaped sprags, or other elements allowing single direction rotation, are used.
A ball bearing motor is an unusual electric motor that consists of two ball-bearing-type bearings, with the inner races mounted on a common conductive shaft, and the outer races connected to a high current, low voltage power supply. An alternative construction fits the outer races inside a metal tube, while the inner races are mounted on a ...
National Bearings Company Limited (NBC) was founded in Jaipur by Shri B. M. Birla in a technical collaboration with Hoffman, UK in the year 1946. It began with the production of ball bearings from the year 1950. Following a political change in the princely state of Hyderabad, the company was renamed as National Engineering Industries Limited.

However the bearing movement also becomes reciprocating rather than continuously rotating, which is a more difficult problem for lubrication. Notable engines to use fork-and-blade rods include the Rolls-Royce Merlin V12 aircraft engine, EMD two-stroke Diesel engines, and various Harley Davidson V-twin motorcycle engines.
Rotating bearings allowed movement in both the horizontal and vertical directions. Both plane bearings and roller bearings were made of metal. In the mid-1900s, deformation bearings began to be used, which were made of rubber. Deformation bearings primarily include elastomeric bearings, the most common type of bridge bearing used today. [5]

The conduit methods were known to be of better quality, but cost significantly more than K&T. [2] In 1909, flexible armored cable cost about twice as much as K&T, and conduit cost about three times the price of K&T. [6] Knob and tube wiring persisted since it allowed owners to wire a building for electricity at lower cost.
