When a machine is subjected to a noise-reduction program, bearings are normally involved. Even when bearings are not generating noise, they may be concerned with noise transfer. Generally, ...

February 16, 2007 In an interesting development, the same technology that is used in noise-cancelling headphones (roughly speaking) is to be applied to heavy marine engines to reduce their noise and ...

Bearing clearance is one of the fundamental aspects of engine building and one that continues to spark debate and divisive opinions—and as with everything from nitrous systems to eating chocolate, ...

Schaeffler’s standard deep groove ball bearings set the benchmark when it comes to relevant technical characteristics, such as minimising friction and noise. Reduced friction means, for example, lower ...

Typically, wheel bearings are like Simon and Garfunkel (or Disturbed, if you prefer) and emit "The Sound of Silence." Not the song, that'd be annoying, but actual silence. However, when wheel bearings ...

Why they matter: Wheel bearings reduce friction and support your wheels’ rotation; failure can cause wobbling, noise, and even wheel detachment. When to replace: Listen for humming, grinding, or ...

Experience shows seemingly identical rolling bearings operated under identical conditions may not last the same amount of time. In most cases, it is impractical to test a statistically significant ...

Back in 1983, I inherited my grandfather's 1973 Buick Apollo, equipped with a low-mileage Buick 350 V8 engine. The car is mostly stored, but I start it up and exercise it every few years. The last ...

Engine noise makes us more nervous than any other automotive sound because noise can mean expense and inconvenience. And, sometimes engine noise is nothing more than a normal dynamic of the engine’s ...
