Precise movements are made with precision slides. Reciprocating linear bearing accuracy, the possible runout in any plane, is typically as low as 0.005 in./in. Because linear bearings are only as ...

Careful measurement is the key to quality work. Work slowly when measuring rod journal diameter to guarantee an accurate reading by ensuring the micrometer is perpendicular to the journal surface. If ...

The primary job of an engine bearing is to establish a low-friction interface for a rotating shaft. Most bearings today are half-round assemblies used around crankshafts, for example. While you might ...

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, ...

Measuring bearing clearances is one of those steps that all good engine builders take to establish a solid and reliable rotating assembly foundation. It can be tedious trying different bearings to put ...

Friction slows equipment, wears components, and renders motion profiles unpredictable. One remedy for linear-motion friction is to use air bearings to carry normally contacting components while ...
