1109-043-212 rotary joint

1109-043-212 rotary joint is a high-performance single channel rotary joint designed specifically for industrial high-speed rotary applications. This model belongs to the Deublin 1109 series and is mainly used in scenarios where coolant or micro lubrication (MQL) media need to be transported from stationary pipelines to high-speed rotating equipment such as machine tool spindles, centrifugal pumps, etc. The core design concept is to balance sealing reliability at high speeds with low maintenance costs, especially suitable for conditions that are sensitive to impurities and require long-term continuous operation.

The sealing mating surface is selected according to customer needs
The external pipe has threads or quick change flange connection method, which has strong installation flexibility
The shell is equipped with oil injection nozzles for reasonable maintenance of bearings, extending their service life
The shell is equipped with observation holes to observe leakage and wear conditions for timely maintenance measures
The air type adopts aluminum or aluminum alloy and copper shell, which has the advantage of good heat dissipation performance under high-speed transmission,
Aluminum alloy shell, equipped with imported SKF and TIMKEN bearings, impregnated graphite rings, 304 stainless steel silicon carbide shaft, and wear-resistant fluorine rubber O-ring, suitable for high-speed rotating equipment, making it more wear-resistant and have a longer service life!
