Installation of DC Oil Seal

●Medium Compatibility:

Suitable for mineral oil, synthetic oil*, and grease.

Note: For synthetic oils (polyglycol/polyalpha-olefin), ensure the maximum operating temperature does not exceed 80°C.

●Temperature Range:

Operates effectively between -40°C and +100°C.

Can withstand short-term temperatures up to 120°C.

●Speed Specifications:

Maximum allowable linear velocity: 5 m/s.

●Speed Calculation Formula:

v [m ⁄s] = shaft-ØD [mm] x RPM [1/min] x π / 60,000

v [ft ⁄s] = shaft-ØD [in] x RPM [1/min] x π / 720

●Stress Tolerance:

Maximum pressure: 0.05 MPa / 0.5 bar
