An overview of methods for determining target C10 values to select tapered roller bearings. These bearings are especially good at handling axial shaft loads.
is this bearing alone water leak resistant? i have diy project that contain shaft with bearing mixing the liquid on a container. can I use this bearing alone to prevnt water leak fro mixer?
No...it is not naturally leak resistant. You can, however, purchase a sealed bearing that will incorporate a polymer seal that also slides against the shaft. They increase friction and will, eventually wear out. Water resistant is also a lot different from water proof. If all you need is water resistance, then you could probably use a sealed bearing. Your best bet is to go to the SKF or Timken or other manufacturers site and open a chat to discuss options. There are seals, alone, that are designed to isolate locations on the shaft...but these are different from bearings...think of a crankshaft seal on a car, for instance, or seals that are required for prop shafts in boats/submarines. Sealing against pressure is a tough proposition that gets expensive.
Shigley's Mechanical Engineering Design text has the images, otherwise I imported CAD drawings into Fusion 360 using the import part menu item. I import the CAD drawings from McMaster Carr,
This is not good, and I have never encountered that problem. If the outer ring, known as the cup, is rotating, it means that the rollers are not sliding properly on the cone and the race. The outer ring is supposed to be secured by a set screw or a press fit or otherwise locked into the housing. Also, you should be using these bearings in pairs ( not required, but advisable) so the induced axial load does not 'push' the shaft/cone out of the cup...that could also be happening. Bottom line, you need to fix that, but be advised that it may have been induced by excess friction in the bearing itself. Sounds like it is time for a new bearing. As an intro guideline to mounting, watch the SKF training video at ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JugU6NHgqVY.html
@@MechaTomics thanks for your response. The machine was run with lubricant below the required amount therefore having insufficient lubrication. However in skf literature they indicate that the only causes for this to happen would be shaft unbalance and incorrect fit during assembly. However I also believe that a higher frictional force would cause this as well as "bearing creep".
