Other important factors are ensuring the hardness and roughness of the shaft are correct. A shaft hardness of HRC 45 is recommended for a rubber sealing lip, with a roughness of Ra 0.4-0.8. A higher shaft hardness of HRC 60 and shaft roughness of Ra 0.1-0.4 is recommended for a PTFE lip.
- 1. Temperature resistance High temperature rubber gaskets can withstand extreme temperatures, making them suitable for use in harsh environments.
- Labor costs are another important factor in the cost of spark plugs and wires. The manufacturing process involves a variety of tasks, such as casting, machining, and assembly, which require skilled workers. The cost of labor depends on factors such as the wage rate, working hours, and benefits provided by the employer.
- There are several different types of shaft oil seals, including lip seals, mechanical seals, and labyrinth seals. Lip seals are the most common type and consist of a flexible lip that comes into contact with the shaft. Mechanical seals, on the other hand, use mechanical components to create a seal, while labyrinth seals have multiple barriers to prevent the entry of contaminants.
Oil seal characteristics

With the help of tips and information from our suppliers, our specialists will be happy to explain how to install oil seals. Please read the instructions carefully before installation.
The sealing lip is always made of a rubber or synthetic material. For oil seals with a rubber outer case (R, RST, GR, GRST), the rubber quality of the sealing lip and the outer case are the same.
In addition to their reliability and durability, floating oil seals are also easy to install and maintain
. These seals do not require complex installation procedures or special tools, making them a cost-effective solution for businesses looking to minimize downtime and reduce maintenance costs. With proper care and regular inspection, floating oil seals can continue to provide effective sealing performance for years to come.
