• Commonly used in machinery operating in high-temperature environments

What materials are used in this seal and how do they contribute to its performance?

The seal is made from nitrile rubber, which offers excellent resistance to oil and grease, ensuring longevity and effective sealing in high-temperature conditions. This material choice enables the seal to perform efficiently in varying operational environments.

How does the design of the sealing lip influence its sealing capability?

The conventional sealing lip design allows for effective contact with the shaft, minimising the risk of fluid leakage. This design also allows for flexibility and adaptability in maintaining contact during motion, enhancing overall sealing effectiveness.

What maintenance considerations should be taken into account for this seal?

Regular inspections are recommended to ensure that the seal remains intact and free from wear. It is also important to monitor operational temperatures and speeds to ensure they remain within specified limits for optimal performance.

What circumferential speed can this product handle, and why is it significant?

This seal can accommodate a circumferential speed of up to 6.93m/s, which is crucial in applications with rapid rotational movements. Adhering to this limit helps to prevent overheating and potential failure due to excessive friction.

In what environments can this seal function optimally?

It is designed for operation in harsh environments, such as those found in the industrial sector, where temperatures can range from -40°C to +100°C, making it suitable for various mechanical and automotive applications.
