Description of Heavy Duty Large Diameter FKM Rotary Shaft V-Seal
Special features Heavy Duty Large Diameter FKM Rotary Shaft V-Seal
-
Suitable for heavy duty applications: Heavy duty large diameter FKM rotary shaft V-seal is specially designed for heavy-duty industrial applications and can withstand high loads and harsh working conditions. They are typically used on large equipment such as large pumps, compressors, and rotating machinery.
- Large Diameter Seals: They have a larger sealing diameter range than traditional seals. This makes them suitable for large-diameter rotary shafts and able to meet the needs of a variety of equipment.
- FKM Material: FKM (fluoroelastomer) is a high-performance material with excellent resistance to heat, chemicals, and wear. It can maintain sealing performance under high temperatures and corrosive media while having a long service life.
- Rotating shaft seal: This seal adopts a V-shaped sealing lip design, which can form an effective seal on the surface of the rotating shaft to prevent liquid or gas leakage. They can withstand high-speed rotation and maintain stable sealing performance.
- Wear Resistance: Since heavy-duty applications often involve high loads and frequent operations, this seal has excellent wear resistance. They can withstand long periods of operation and friction and are not prone to wear or failure.

How it (Heavy Duty Large Diameter FKM Rotary Shaft V-Seal)works?
The seal body has a stretch fit on the shaft and the flexible lip seals against the counter face. As the shaft rotates the seal also acts as a slinger. The centrifugal force decreases the elastomer lip's contact pressure as speeds increase - keeping friction losses and heat to a minimum.
- shaft Surface Speed: To 1600 fpm (8.1 m/s)
- Shaft Size Range: 17.720 to 79.000 inches (450.1 to 2000 mm)
- Maximum (STBM) Misalignment: 1 to 4 degrees
- Typical Applications:
- This large cross-section V seal(or V-ring) is used in a variety of heavy-duty applications such as rolling mills, work rolls, and backup rolls.
