Scrapped components: Typical scrapped components include one-time-use soft goods such as packing, body gasket, thrust washer, seat gaskets, any severely damaged components and seats. What you can and can't re-use heavily depends on your valve concept. Repairable components: Typically these include the ball, stem, body and end piece, and metallic parts …
Read OnWelding bearing damage. 11-30-2011, 07:22 PM. Just wondering if anyone has experience with bearing damage caused by welding. I discovered that four one inch tack welds were made on a piece of machinery. The ground was clamped in a position where the current likely flowed through a huge bearing when these tacks were welded.

Read On• Shaft deflection = diagonal contact with ends of bearing • Longer machine = Higher production costs The longer and heavier the rotor, or the more flexible the shaft, the more shaft deflection (Figure 3) should be expected. Shaft deflection may force the designer to increase the clearance between the sleeve bearing and journal.
Read OnBent Shaft Straightening. A bent shaft can occur as a result of damage during shipment, rigging, or operation. Shaft straightening methods, when properly applied, can sometimes be used to salvage damaged shafting. Because of the …
Read OnTherefore, the motion will be transferred to other components which are forced to accept the unusual motion due to the ball joints being the control arm bushings. By that, the bushings will get damaged easily. Bad ball joint can cause many damage to your car. Secondly, worn ball joints can lead to car accidents when it completely breaks.
