The Rolamite bearing has very little friction. A Rolamite is a technology for very low friction bearings developed by Sandia National Laboratories in the 1960s. [1] It consists of two cylindrical rollers held captive in a channel by an S-shaped metal strip. The strip is under tension, which keeps the rollers pressed together with the strip ...
Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races. Common ball bearing designs include angular contact, axial, deep-groove, and preloaded pairs.
Silicon nitride bearing balls, in diameters ranging from 1 to 20mm. Bearing balls are special highly spherical and smooth balls, most commonly used in ball bearings, but also used as components in things like freewheel mechanisms. The balls themselves are commonly referred to as ball bearings. [1] This is an example of a synecdoche.

An indoor rower, or rowing machine, is a machine used to simulate the action of watercraft rowing for the purpose of exercise or training for rowing. Modern indoor rowers are known as ergometers (colloquially erg or ergo) because they measure work performed by the rower (that can be measured in ergs). Indoor rowing has become established as a ...
Thrust ball bearings, composed of bearing balls supported in a ring, can be used in low-thrust applications where there is little axial load. Cylindrical roller thrust bearings consist of small cylindrical rollers arranged flat with their axes pointing to the axis of the bearing. They give very good carrying capacity and are cheap, but tend to ...
Bow ball A small, soft ball no smaller than 4 cm diameter securely attached to a rowing or sculling boat's bow. Primarily intended for safety, but also used in deciding which boat crossed the finish line first in very close races. Bow number A card displaying the lane number assigned to the boat for a race. Bow rigged
