FAQ
A1: The full-flow design prevents impurities in the coolant from accumulating and avoids clogging pipelines and joints; the labyrinth structure + multiple large leakage ports effectively block impurities from entering the ball bearings, protecting the bearings from damage, reducing equipment failures during deep hole machining, and ensuring continuous operation.
A2: Yes. Standard pressure models can be upgraded to 120 bar high-pressure compatibility by replacing high-pressure resistant rotary seals. Customization is also supported; connection methods and sealing configurations can be adjusted according to actual equipment requirements to adapt to special working conditions.
A3: Yes. With a balanced mechanical seal design and high-quality sealing components, stable sealing is maintained under operating conditions of 15000 RPM high speed, 70℃ high temperature, and corresponding pressure, preventing coolant leakage and meeting the operation requirements of high-speed machine tool spindles.
