New Solution for Powder Leakage at the Shaft End of Kneading Machines — BrowSeal Rotary Shaft Seal
Common kneader sealing shaft ends typically use packing seal technology, where frequent leakage issues such as dust leakage and material jamming causing seal damage often require shutdowns for maintenance. The new sealing solution is a high-performance rotary shaft seal, which addresses the frequent dust leakage problems in kneading machines, enhances production line capacity, and offers better cost-effectiveness in overall usage.

Sealed Friction Transfer - Mainshaft Wear Transferred to Sealed Wear-prone Components
Why do packing seals wear the shaft, while rotary shaft seals do not? The key lies in friction transfer. Traditional seals involve direct hard contact between the shaft and packing material, causing continuous wear as the shaft rotates. In our shaft seals, the internal silicone elastomer is interference-fitted with the shaft, rotating synchronously with it and conforming perfectly to the shaft surface, completely avoiding friction damage. Then, the PTFE rotor rotates relative to the metal stator plates, turning the shaft-wearing process into rotor-wearing. The shaft never contacts the wearing components, keeping the main shaft smooth and pristine. The same rotation, different outcomes.

Easily handle factory inspections, with clean floor surfaces around rotary shaft seals demonstrating standardized management
When customers visit the factory, their initial impression is immediately affected by the powder residue on the floor. This is a common experience for owners in new energy materials, food, and pharmaceutical industries. During 5S inspections and customer factory audits, a clean floor is a basic requirement. Even if the shaft ends leak powder daily, making it impossible to sweep completely, the customer may not say it outright but already has a judgment in mind. The rotary shaft seal's triple-sealing structure, with positive pressure blowing outward, prevents powder from escaping easily. A clean workshop floor ensures greater confidence during factory inspections.
