Standard angular contact ball bearing FAQS

QDo ball bearings need lubrication?

ASo most bearings use cages to separate and evenly space the balls. These cages cause friction and to reduce this friction, you generally need to lubricate your bearings, often with thick grease to ensure a long lifespan.

QHow is a steel ball bearing used?

ABy minimizing friction, a steel ball bearing also reduces wear between two pieces of metal, which can reduce maintenance requirements and extend the like of the objects. To understand how a steel ball bearing is used, it's helpful to picture the wheels on a skateboard.

QIs oil suitable for ball screw lubrication?

AThe short answer is yes: ball screws can be lubricated with either grease or oil. Grease is more commonly used for ball screw lubrication because it doesn’t entail complicated delivery methods, and it requires less frequent re-lubrication intervals.

QWhat sizes are ball bearings?

AThe specification limits under which the ball bearing can operate are 0.74 inch (lower) and 0.76 inch (upper). Past experience has indicated that the actual diameter of the ball bearings is approximately normally distributed with a mean of 0.753 inch and a standard deviation of 0.004 inch.

QWhat is ball screw thrust?

AA ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction.
