Bearing Tolerances & Clearances ISO Bearing Tolerances

When a bearing’s inner race is mounted on a shaft with an interference fit, some expansion of the inner race O.D. (roller path or ball groove) occurs. This has the effect of reducing the manufactured or “bench” internal clearance of the bearing. This is a very important consideration when designing a machine.

point (fig. 3). Those same lines along the surfaces of ball or cylindrical roller bearings are parallel. The advantage of this design is that the tapered rollers have a positive alignment with the shaft. That is, each roller will align itself perfectly on the tapered faces of the cup (outer race) and cone (inner race).

Rod mills, how they function Mine Engineer.Com

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.
