BRYANT RU2

Multi-spindle OD grinder
for precision components

The Bryant RU2 is a multi-surface grinder capable of utilizing up to four spindles, multiple workheads, wheelheads, and dressing systems, for optimum productivity in a compact footprint. The modular machine design provides great flexibility for all applications, meaning the RU2 should be your first choice for both simple and complex processes up to 250mm in diameter.

Optimum productivity without compromising on precision

Bryant is the trusted name in today's most demanding industries. Built to guarantee exceptional thermal stability and with particular care paid to overall machine stiffness, the Bryant RU2 ensures the highest level of repeatable accuracy. Low maintenance, reduced energy consumption, and increased uptime drive a lower total cost of ownership. 

Features to note include the granite epoxy bed, linear motors, 0.1µm resolution glass scales – all designed for maximum stiffness and accuracy.

    Multi-slides, multiple possibilities

    Multiple slide configurations, in conjunction with modular mechanisms, assure the machine can be tailored to each individual process. Fives' decades of manufacturing expertise have resulted in a catalog of readily available workheads, wheelheads and dressing systems to ensure you get maximum productivity in a compact footprint.

    Customers who need high-precision, high-volume grinding choose the Bryant RU2 for bore, seat and face grinding applications. In addition, it is used to grind outer diameter features of fuel systems, valve trains, bearings, turbochargers and more.

    Low-maintenance OD grinding

    Low friction ways systems guarantee very low maintenance, ensuring you have maximum uptime. As with all Bryant machines, you can also expect:

    • Optimum dimensional and geometric accuracy
    • Excellent thermal stability
    • A small, compact footprint
    • Linear motors for all linear axes – no backlash
    • Fully automated system

    OD grinding with high productivity

    All this precision does not come at the expense of productivity. Spindle speeds up to 120,000rpm and a patented hydrostatic round bar in-feed system enable us to achieve the highest level of productivity.
