Bearing

Engineers can get rid of clutches, cams, and other mechanical controls by using rolling-ring bearings in autoreversing motion-control systems.

Spiral retaining rings from Smalley Steel Ring Co., Wheeling, Ill., give designers a new type of tamperproof fastener.

A golf-ball-like surface improves lubricant flow inside bearings.

A new line of wipers from Schneeberger, Bedford, Mass., protects monorail carriages and guideways from harsh environments.

JetEdge systems are used in a variety of industries from manufacturers of titanium hips to aerospace suppliers.

Today's customers demand machine tools that are precise and durable. Bearing systems play a major role in determining accuracy and life.

To overcome heat, vibration, and wear problems, tool builders can turn to ball screws and spindle bearings containing Cerbec ceramic balls.

Ball-to-ball friction in bearings generates heat, limits the speed, and shortens the life of linear-motion guides.

Composite journal bearings can operate without external lubrication, even in harsh environments that challenge most conventional types.

From left: sharply crowned, gradually crowned, and radiused-ring bearing plates.

A tolerance ring retains a guide bearing
in the gimbal housing of a sterndrive engine.

Shown are plots of representative bearing
types with standard inner and outer race curvatures.

Hollow-cylindrical-roller bearings are intended for light load applications, including all types of grinding, machining, and milling spindles.

Hollow-cylindrical bearings, rolling-ring linear actuators, and self-aligning bearings are some of the topics covered in this bearings reference guide.

Sunon Inc., Brea, Calif., devised a fan in which the permanent magnet in the motor's rotor assembly interacts with a metal plate to generate a magnetic field.
