The company sells Baldor-Reliance and ABB branded industrial electric motors. Products are available in both IEC and NEMA configurations and range from fractional to 100,000 horsepower. The company also sells the Dodge brand of mechanical power transmission products, including mounted bearings, enclosed gearing, couplings, sheaves, and bushings.
As speeds or bearing loads later increased, forced pressure lubrication became more prevalent and the ring oiler fell from use. A ring oiler is a simple device, consisting of a large metal ring placed around a horizontal shaft, adjacent to a bearing. An oil sump is underneath this shaft and the ring is large enough to dip into the oil.
Working principle for a ball bearing; red dots show direction of rotation. A four-point angular-contact ball bearing. A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It ...
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 ...
Grease fitting on a bearing A grease nipple on the driver's door of a 1956 VW Beetle. A grease fitting, grease nipple, Zerk fitting, grease zerk, Alemite fitting, or divit is a metal fitting used in mechanical systems to feed lubricants, usually lubricating grease, into a bearing under moderate to high pressure using a grease gun.
Fluid bearings are typically quieter and smoother (more consistent friction) than rolling-element bearings. For example, hard disk drives manufactured with fluid bearings have noise ratings for bearings/motors on the order of 20–24 dB, which is a little more than the background noise of a quiet room. Drives based on rolling-element bearings ...
A true grease consists of an oil or other fluid lubricant that is mixed with a thickener, typically a soap, to form a solid or semisolid. [1] Greases are usually shear-thinning or pseudo-plastic fluids, which means that the viscosity of the fluid is reduced under shear stress.
Nowadays, with proper industrial parts washer equipment, it is accepted that aqueous cleaners remove oil and grease as easily as solvents. Another approach is with solid cleaning media (blasting) which comprises the CO 2 dry ice process : For tougher requirements, pellets are used while for more sensitive materials or components CO 2 in form of ...
