Bearing heaters typically range from 1 kVA to 25 kVA and are used to heat parts from 1 to 650 kg (2.2 to 1,433.0 lb), dependent upon the application. The power required is a function of the weight, target temperature and cycle time to aid selection many manufacturers publish graphs and charts.
Tempering (metallurgy) Differentially tempered steel. The various colors produced indicate the temperature the steel was heated to. Light straw indicates 204 °C (399 °F) and light blue indicates 337 °C (639 °F). [1][2] Tempering is a process of heat treating, which is used to increase the toughness of iron -based alloys.
A sealed deep groove ball bearing. In mechanical engineering, a rolling-element bearing, also known as a rolling bearing, [1] is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two concentric, grooved rings called races. The relative motion of the races causes the rolling elements to roll with very ...
In metallurgy and materials science, annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for an appropriate ...
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.
Interference fits are commonly used with aircraft fasteners to improve the fatigue life of a joint. These fits, though applicable to shaft and hole assembly, are more often used for bearing-housing or bearing-shaft assembly. This is referred to as a 'press-in' mounting.
Thermal stress. In mechanics and thermodynamics, thermal stress is mechanical stress created by any change in temperature of a material. These stresses can lead to fracturing or plastic deformation depending on the other variables of heating, which include material types and constraints. [1] Temperature gradients, thermal expansion or ...
DN factor, also called DN Value, is a number that is used to determine the correct base oil viscosity for the lubrication of various types of bearings. [1][2][3][4][5] It can also be used to determine if a bearing is the correct choice for use in a given application. [3] It is a product of bearing diameter (D) and speed (N). [1][2]
