First, what is a bearing housing?
Simply put, a bearing housing is the housing and base of a bearing, like a snail and its shell.It provides stable and accurate support and positioning for the bearing, and can withstand the forces from the bearing and transmit them to the machine base or frame.
Secondly, why can't a bearing housing be replaced?
Why can't the bearing be directly mounted on the machine?-1)The shaft must rotate so that the inner and outer rings of the bearing must be perfectly concentric. Bearing housing are precision-machined to ensure the precise location and dimensions of the mounting holes, ensuring optimal bearing performance.
-2)Bearing housing provide perfect protection for the bearing during operation, isolating it from most impurities and dust.
-3)The advent of bearing housing significantly reduces installation difficulty and time costs.
There are many varieties and types of bearing housing, but we only need to remember two core types.
-1)Integral bearing housing: These housing are cylindrical in shape, simple in structure, and offer excellent performance. Examples include machine tools and motors.
Are the top covers of separate bearing housing round or square?
The round ones are called "P housing," and the lower ones are called "SN housing." The square ones are suitable for heavy loads, while the round ones are more flexible.
