1. Integral vulcanized seal ring
The integral vulcanized sealing ring process is Closed -loop molded vulcanized sealing ring which is suitable for the initial assembly of bearing. The molded product has the advantage of compact structure and dimensional stability. The products are not having joint which can completely eliminate the defects caused by manual splicing, and it also can reduce the stretching or squeezing under installation and guarantee its lifetime.
2. Sealing strip
We also can supply the sealing as strip which is suitable for the operation and maintenance of wind field and on-site technical improvement.

MAIN SHAFT BEARING SEAL FOR WIND TURBINE

Main shaft bearing seals of wind turbines are made of highly specialized rubber material reinforced with durable fabric and stainless steel springs. Their main purpose is to ensure long-term, defect-free, and efficient operation of turbine rotor blades through sealing in grease lubricants.

Main-vice lips seal(TJRF Type)

¡¤  Introduction
¡ñ The main-vice lips seal(TJRF) design has stronger and more flexible waist and lip, the anti-pollutant lip prevents dust from entering bearing casing.
¡ñOffset in circular center position (to maximum of 1.5mm) of the rotating main shaft is a primary cause for seal failure; TJRF seal design has a longer waist, thus able to tighten around the main shaft and follow-up,to compensate for the failure mode for double-fed wind turbine systems with double main shaft bearings.
¡ñ PTFE 0.02¡« 0.1mm sprayed at lips to enhance the abrasion resistance and service life.

Double main lips seal(TJY)

¡¤   Introduction
¡ñDouble lips will has the effect of double seal, the second seal will prevent the dust well.
¡ñDesigns for double-fed with single shaft bearing. Because the axial and radial offset issue of single main shaft bearing is worse than double main shaft bearing, wind speed and direction will also affect it. The usual seal design can¡¯t satisfy that working condition, especially for radial offset and will cause grease leak. The special construction of the waist will provide better following-up and will make up for axial and radial offset of the shaft to ensure good seal performance.
¡ñ Chinese patented product.
