A tolerance ring retains a guide bearing in the gimbal housing of a sterndrive engine. A tolerance ring is a mechanical fastener that also acts as a flexible shim. The rings are formed from thin ...

When we think critical, under-the-hood car parts, we envision tough metal parts operating under the harshest conditions involving high heat, cold, and grime of all kinds. Plastics may not even be a ...

Geometric tolerance standards for precision-class tapered roller bearings (TRB) used in machine tool applications are controlled by the ISO and ABMA standards, and must be understood in order to ...

The challenge that machine tool builders face when designing spindles for milling machines and lathes is selecting bearings with the optimal balance of speed, load-carrying capacity, stiffness, and ...

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 ...

We have seen some compelling but anecdotal evidence suggesting that wheel-end tightness can affect fuel economy — sometimes significantly. Joel Morrow, head of research and development, Ploger ...

Dynaroll miniature ball bearings make a dime look large. (Left)Grooves make room for adhesive to flow without raising runout. (Right)Make sure the shoulder rim clears the opposing ring when locating a ...
