R2A Series

The R2A Series offers a carriage bearing design that produces lower bearing friction, smoother operation and zero running clearance. A flexible seal prevents environmental contamination and ensures long life to provide an effective, industrial-grade solution. Belt-drive models offer the most rapid moves, while screw-drive designs offer the highest thrust capacity and repeatability.
