The operational requirement for the movable portion of the bearing block is that it must rotate freely and tilt 4 degrees in any direction. This specification is crucial for ensuring that machinery operates smoothly under varying loads and conditions. Allowing for both rotation and a slight tilt enables the bearing block to accommodate misalignments and vibrations that may arise during operation. This flexibility helps maintain consistent contact between moving parts, reducing wear and enhancing the lifespan of the components involved.

In contrast, having a bearing block that is fixed in place would not allow for the necessary adjustments to maintain alignment as parts move relative to each other, potentially leading to increased friction and premature failure. Similarly, having no movement capability would completely negate the function of the bearing, which is to support rotating elements while allowing for smooth motion. Thus, the ability to rotate and tilt ensures optimal performance and durability.
