This resulted in loud noise during operation, a short running life, and did not have the ability to be run at high speeds.  \n20 years later, rotary ball bearings with ball cages were developed. This type was quieter in operation and capable of high rotational speeds. Although containing less balls, it provided exellent running life and contributed to the major success of rotary bearings. The history of the needle bearing reveals how quality improved through the use of ball cages. Balls, at their  \ntions and at twice the speed of each of their rotation. This resulted in severe wear, loud noise, and a short running life. The massive pressure from the metal to metal contact and slip between the balls also caused the oil film to break down.  \nAlternatively, balls and ball cage contact each other over a large surface area and at half the relative velocity. This prevents the break down of oil and provides for quieter operation, higher rotational speeds, longer running life and extended maintenance.  \nAt  , we utilized our many years of experience along with innovative manufacturing techniques to develop the new Caged Ball™ technology, and we have built this technology into the new generation of smooth-running LM guides.
