BM3 Self-Aligning Ball Bearing

It is made in India. Chrome steels are particularly useful in applications that involve high speeds or temperatures. The chromium content makes it resistant to oxidation and corrosion under most circumstances. It also has the ability to absorb considerable amounts of heat, which allows it to retain properties like flexibility even when operating at high temperatures. One of the best ways to describe chrome steel is as a superalloy. These alloys are designed with specific properties in mind and are generally more expensive than non-alloyed materials. When choosing bearings, the material used in the bearing races is just as important as the materials used in the rolling elements. Depending on their intended use, bearings can be made from a variety of metals and alloys. The most common bearing materials are brass, bronze, chromium steel, high-carbon steel and stainless steel. Some of these materials are better suited for certain applications than others. Ceramic and plastic balls are not generally used in precision, small-diameter bearings because they tend to deflect under load. Bearing rings made of nylon or hard rubber may be used when special conditions make metal rings unsuitable, such as when operating at elevated temperatures or when exposed to chemicals that could cause corrosion of metallic components. Bearing selection is based on many factors including size, load capacity and speed rating. Bearing is a mechanical device which is used to reduce friction and wear in moving parts. The mechanical structure of bearing consists of a central shaft, called the spindle and an outer ring called the race. A ball bearing uses small spherical balls as rolling elements between the races. The balls have a diameter that is 20% less than the inner diameter of the raceway so that they can move freely. The balls are permanently locked into place and do not fall out when the bearing is not under load. Some bearings are single-directional while others allow for motion in two directions. For this type of bearing, there are two different styles; one allows for movement from side to side while the other allows for radial and axial movement.
