oil seal 29x44x7. As the shaft rotates, the seal provides a cushioning effect and reduces the amount of contact between the two surfaces. This not only extends the life of the shaft and housing but also improves the overall efficiency of the machine by reducing energy losses due to friction. 
metallic oil seal. This versatility makes metallic oil seals indispensable in industries that require sealing solutions for diverse fluids, such as petrochemical processing and chemical manufacturing. Modern engine concepts, like higher engine speeds and oil temperatures, longer intervals between oil changes and lubricants with modern additives, require new solutions for dynamic seals. They have to withstand the high loads lastingly. PTFE technology is the answer, since it perfectly meets these demands.

Various materials with unique properties are utilised in the construction of rotary shaft seals, allowing manufacturers to tailor the sealing solution to specific industry requirements and ensure optimal performance.
Another factor that can affect the cost of new spark plugs is the brand. Some well-known brands in the automotive industry may charge a premium for their spark plugs due to their reputation for quality and reliability. However, there are also more affordable brands that offer reliable performance at a lower cost.
