Miniature Bearings from Dynaroll



Miniature Bearings - Dynaroll Corporation was founded in 1988 and has become one of the world's largest independent suppliers for miniature bearings to the automotive, medical, aerospace and other high-precision industries.  Miniature bearings Manufacturing facilities in San Fernando, California and Kuala Lumpur, Malaysia.

Miniature Bearing Manufacturing - Ball Bearing Overview.

For miniature bearings, single-row deep groove radial ball bearings are the most common type of miniature bearings, having a wide range of suitable applications. The raceway grooves on both inner and outer rings have circular arcs of slightly larger radius than that of the balls. In addition to radial loads, axial loads can be applied in either direction. Because of their low torque, they offer high speed operation with low power loss. miniature bearings and instrument radial ball bearings are made with very high levels of precision, therefore these are generally used in applications where accurate rotational performance and low torque is necessary, and load capacity is a secondary issue.

Miniature Bearing - Tables
The miniature bearings listed in these ball bearing tables are available in a variety of different grades. As discussed, ABEC and ISO standards only cover part of the overall picture for ball bearings, particularly for more demanding applications. Beyond the basic dimensions and tolerances of ball bearings, characteristics such as raceway finish, cage quality, ball matching and consistency of internal geometry can affect the performance of an individual bearing in its application. These characteristics are generally determined by the level of sophistication of the equipment used to manufacture the miniature bearings. This sophistication, in turn, affects the cost and availability of the bearing. All Dynaroll bearings are guaranteed to meet stated performance specifications, and bearing quality is monitored according to ISO 9000 quality standards. It is recommended that demanding applications for ball bearings are discussed with a bearing engineer at Dynaroll.
