NEW BEARINGS FOR BALLSCREW DRIVES

ROD 260 BallscrewFor several years R. A. Rodriguez has marketed the UNITEC brand of ballscrew support bearings designed for high performance machine tool applications. Now in addition to the high load and exceptional performance capabilities of this needle roller bearing range, the company has introduced a new range of ball bearings to meet more general high precision needs of ballscrews.

Sourced from the R. A. Rodriguez German facility, the DRF/DRN double row ball bearings for screw drives are high precision components with a contact angle of 60

New energy efficient twin tandem wheel bearing cuts fuel consumption and emissions on vehicles

Twin TandemThe Schaeffler Group has developed an innovative, energy efficient four-row, angular contact ball bearing, which replaces conventional tapered roller wheel bearings, resulting in reduced fuel consumption and emissions on trucks, SUVs and light vans, but which potentially could be developed for use in other heavy engineering applications

By replacing

How Are Your Bearings Holding Up? Find Out with Ultrasound

UltrasoundA condition-monitoring program based on ultrasonics can catch problems before they turn into catastrophes, and can find leaks that could be costing you money.

An effective condition-monitoring program provides many benefits, ranging from improved asset availability to reduced energy consumption. One primary focus of condition monitoring is the status of bearings, whose health (or lack of it) can mean the difference between meeting production goals and causing chaos. Should even a single bearing fail, the consequences can be damaged equipment and product, a production run stopped, parts that must be ordered for repairs, and considerable man-hours wasted.

A program for monitoring bearing condition need not be extremely complicated, nor does it necessarily require a large investment of capital to get it going. One technology that is both cost-effective and relatively easy to incorporate in such a program is air-borne/structure-borne ultrasound.

Seals for the ultimate challenge - the cockpits of jet fighters

TornadoAt service ceilings of up to 15,000 meters, maximum speeds of 2,000 kilometers per hour, rates of climb of 12,000 meters per minute and under extreme pressures, the seal on the jet fighter cockpit presents the ultimate sealing challenge. Even a pinprick in the seal between the cockpit and the plane could put the pilot

Using Vibration Analysis to Detect Early Failure of Bearings

Schaeffler BearingsDr. S. J. Lacey, Engineering Manager, Schaeffler (UK) Ltd

Vibration produced by rolling bearings can be complex and can result from geometrical imperfections during the manufacturing process, defects on the rolling surfaces or geometrical errors in associated components. Noise and vibration is becoming more critical in all types of equipment since it is often perceived to be synonymous with quality and often used for predictive maintenance.

Rolling contact bearings are used in almost every type of rotating machinery, whose reliable operation very much depends on the type of bearing selected and the precision of associated components such as shafts, housings, spacers and nuts.
