What percentage of friction is added to a Common Bearing?

The correct percentage of friction added to a Common Bearing is typically recognized as 10%. In the context of theatre rigging and mechanical systems, friction is an important factor to consider as it affects the efficiency and performance of bearings.

When a bearing operates, it is essential to account for friction to ensure accurate calculations for load-bearing capacity, torque, and overall system performance. The standard practice acknowledges that adding around 10% to the calculated friction allows for a more realistic assessment of how the bearing will function under operational conditions. This adjustment helps in ensuring that systems remain safe and efficient, particularly in the dynamic environments often found in theatre rigging.

In contrast, other percentages do not align with common industry standards for friction losses in common bearings, which is why they are not considered accurate in this context.
