2. Rolling-element bearing - Wikipedia

   en.wikipedia.org/wiki/Rolling-element_bearing

   The third character is the radial clearance, which is normally defined by a number between 0 and 9 (inclusive), in ascending order, however for radial-thrust bearings it is defined by a number between 1 and 3, inclusive. The fourth character is the accuracy ratings, which normally are, in ascending order: 0 (normal), 6X, 6, 5, 4, T, and 2.

3. Plain bearing - Wikipedia

   en.wikipedia.org/wiki/Plain_bearing

   The design of a plain bearing depends on the type of motion the bearing must provide. The three types of motions possible are: Journal (friction, radial or rotary) bearing: This is the most common type of plain bearing; it is simply a shaft rotating in a hole. [3]

4. Conveyor pulley - Wikipedia

   en.wikipedia.org/wiki/Conveyor_pulley

   A conveyor pulley is a mechanical device used to change the direction of the belt in a conveyor system, to drive the belt, and to tension the belt. Modern pulleys are ...

5. SKF - Wikipedia

   en.wikipedia.org/wiki/SKF

   The startup and growth of SKF depends not only on technical inventions but also on industrial and corporate management strategies and power. Axel Carlander was a co-founder of SKF as a co-owner and member of the board of Gamlestadens Fabriker AB, which corporate policy provided conditions for experimenting with the new bearing models and the startup of SKF, and also he was the first chairman ...

6. Pulley - Wikipedia

   en.wikipedia.org/wiki/Pulley

   A sheave or pulley wheel is a pulley using an axle supported by a frame or shell (block) to guide a cable or exert force. A pulley may have a groove or grooves between flanges around its circumference to locate the cable or belt. The drive element of a pulley system can be a rope, cable, belt, or chain.

7. Conveyor belt - Wikipedia

   en.wikipedia.org/wiki/Conveyor_belt

   A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types of conveyor systems.A belt conveyor system consists of two or more pulleys (sometimes referred to as drums), with a closed loop of carrying medium—the conveyor belt—that rotates about them.

8. Bearing (mechanical) - Wikipedia

   en.wikipedia.org/wiki/Bearing_(mechanical)

   A ball bearing. A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts.The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.

9. Belt (mechanical) - Wikipedia

   en.wikipedia.org/wiki/Belt_(mechanical)

   Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel. In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the ...
