A warm bowl of chili is perfect after a long day of hiking. In your cast iron Dutch oven, sauté onions, bell peppers, and garlic until soft. Add ground meat (or a meat substitute) and brown it thoroughly. Then, mix in canned tomatoes, kidney beans, chili spices, and simmer over the fire. This one-pot meal is rich in flavor and will warm you from the inside out.
Requirements of the shaft
Even more important than a correct interference fit of the Oil Seal is a perfectly smooth shaft in the region of the seal, particularly if shaft surface speed is high and the medium to be sealed is under a certain amount of excess pressure. The surface roughness of the shaft depends on the average profile depth Ra of the tool marks caused by the machining process. Oil Seals made of PTFE require, independent of the surface speed, a surface roughness of between 0,1 to 0,2 mm, because PTFE has less wear resistance than rubber seals. For normal circumstances, the shaft in the region of the seal must have a surface roughness of approximately: To summarize, the surface of the shaft in the region of the seal should not have noticeable machining marks. For pivoting shafts and other difficult or critical sealing applications, it is recommended that Oil Seals with a helical groove hydrodynamic pattern, which has a pumping effect, be used. When grinding and polishing, an axial movement of the grindstone along the shaft must be avoided in order to prevent machine lay.- 3. Sealant Application Apply a sealant to the gasket surface to enhance the sealing performance. Use a silicone-compatible sealant that is recommended by the gasket manufacturer.
made of a yieldable resilient material having flat sealing faces and comprising two ring portions connected together by an annular portion substantially v-shaped in cross-section which may yield or expand as the mounting requires.

These seals are designed to fit snugly around the shaft of the machine, preventing oil from leaking out while also keeping dirt, dust, and other contaminants from entering.
