Manufacturer: Fukudaco

Overview

Designed for machinery in petrochemical plants, paper mills, steel mills, and more, such as steam turbines, pumps, motors, gearboxes, pillow blocks, and mixers. Each labyrinth seal is custom-designed for specific equipment. With IP66-equivalent sealing performance, it prevents water and dust from entering the bearings, protecting them throughout their expected lifespan.

Applications

• Pumps
• Motors
• Gearboxes
• Pillow blocks
• Paper mill rolls
• Powder handling equipment

Features

• Forms a complex labyrinth structure with high sealing performance through the combination of rotor and stator.
• Prevents air movement even when stationary, thanks to the VBX® ring.
• The non-contact design eliminates friction, wear, and heat generation, ensuring a long lifespan.

Further evolved bearing isolator “VB45 series”

The VB45 series is Inpro/Seal’s latest series of bearing isolators. The chamber angle of the conventional VBX® ^ring (vapor O-ring) is inclined at 45 degrees, making the seal thinner while maintaining high sealing performance. It has already been adopted in many production facilities both in Japan and overseas.

VB45-S ^™ (16mm thin with IP66 equivalent sealing performance)

VB45-S ^™ maintains the same high sealing performance as before with a thickness of about 16mm. In addition, the D groove for oil bath lubrication has been enlarged, and the sealing performance against oil leakage has been strengthened.
