Pick the proper seal for your bearing with the NBC bearing.
- A high temperature oil seal is primarily constructed from materials that exhibit exceptional resistance to heat degradation. Materials like silicone rubber, fluoroelastomers, and carbon graphite are commonly used due to their excellent thermal stability and chemical inertness. They can endure temperatures ranging from -50°C to 300°C or even higher, depending on the specific compound used. The unique composition of these seals ensures minimal swelling, hardening, or softening, thereby preserving their sealing effectiveness over extended periods.

The dimensions of the 25x47x7 oil seal refer to its inner diameter, outer diameter, and thickness, respectively. These measurements are important in ensuring a proper fit for the seal in the machine or engine it is intended for. By providing a secure seal between moving parts, the oil seal helps to maintain proper lubrication in the machine and prevent the loss of oil.
Aspects to consider when selecting oil seals
Metal O.D. wall type Ensures improved fitting retention between the seal O.D. and the housing bore.
• Machining of lip surface (stable oil drip under pressure)
