Rubber Bellows Mechanical Seal WMMG912(INCH)

Rubber bellows mechanical seals WMMG912(INCH) is non-directional, technically advantageous, and extremely versatile. Rubber bellows mechanical seals WMMG912(INCH) can be used regardless of the direction of the rotation since the driving torque is not transmitted through the single-coil spring. The required driving torque is enhanced through the rubber bellow which fits on the shaft through the interference fit between the collar, rubber bellow, and shaft. Shaft runout is compensated by Elastomer bellow and spring due to its self-aligning capability. Rubber bellows mechanical seals WMMG912(INCH) protects Shaft/Sleeve from Fretting.
