Rotary Union for Coolant Application

Micro Seals coolant rotary Unions is bearing-supported, single-piece design for ease of installation and replacement. We offer various styles, rotor and bore, to fit nearly all machining applications. Micro Seals coolant rotary Unions is designed with closed seal technology to reduce seal wear by remaining closed with or without the presence of media. The bearing supported rotary Unions can absorb the spindles thrust load reducing early wear.
Micro Seals Non-contact design allows unlimited dry running without media pressure to prevent early seal wear. Dry running or non-contacting rotary Unions are best for machining that utilizes through-spindle coolant. Threaded rotor is available in radial and axial connections with ease of installation. Special precision angular contact ball bearing with wide spacing to absorb large side loads and reduce wear and high speed.

The Coolant rotary Unions features Precision lubricated for life bearings for longer life, reducing downtime and maintenance for rotary Unions coolant applications. Micro Seals compact pneumatic and hydraulics design can configured to fit your custom application.
