The taper ratio of these bearings typically ranges from 112 to 130, allowing for a balance between load distribution and load capacity

Bearings play a crucial role in numerous mechanical and engineering applications, facilitating smooth motion and reducing friction between moving parts. One such bearing that is widely utilized is the 6403 bearing. This article delves into the dimensions and specifications of this particular type of bearing, providing a comprehensive understanding for engineers, technicians, and enthusiasts alike.

Another advantage of taper rolling bearing supports is their adaptability to various mounting configurations. They can be used in fixed, floating, or location arrangements, providing designers with flexibility when integrating them into new or existing equipment. This versatility, combined with their robust construction, ensures that these bearings can withstand the rigors of industrial environments, including exposure to moisture, dust, and extreme temperatures.

Bore Size The bore size refers to the diameter of the inner ring of the bearing. It is measured in millimeters (mm) and is typically specified as an integer value. For example, a bearing with a bore size of 60 mm would have an inner ring diameter of 60 mm.

This bearing finds its application in a broad spectrum of industries, from automotive to aerospace, from home appliances to precision instruments
