RK FIXATOR SYSTEMS level and align machinery to tolerances of tenths (0.0001″) and make it possible to vary adjustments at any time, even under maximum loads requiring only a small hand wrench to adjust. Time consuming work and production losses normally associated with alignments are eliminated. While affording the most rigid machine-to-foundation connection available, other benefits include built-in compensation for uneven areas in foundations and machine bases. True vertical lift, made possible by a 3-piece wedge design to eliminate lateral movement as machines are raised or lowered, makes the RK FIXATOR the “state-of-the-art” anchoring/alignment system.
Ultra-Precision Leveling and Alignment for Metalworking Machinery
UNISORB® Fixators® are engineered for ultra-precision leveling and alignment of metalworking machinery where micron-level accuracy is critical. Designed for support-critical applications, these advanced mounts enable precise machine alignment without loosening anchor bolts—ensuring stability while making fine adjustments.
Fixators® allow for controlled, micro-level adjustments that simplify installation and realignment, significantly reducing downtime and improving setup efficiency.
Their rigid, high-stability design maintains alignment under load, helping preserve machine accuracy and repeatability in demanding production environments.
Ideal for CNC machines, grinders, and other precision metalworking equipment, Fixators® deliver long-lasting alignment, improved machining performance, and consistent operational reliability. The result is faster setup, reduced maintenance interruptions, and sustained peak machine performance.
