BRYANT RU2

Multi-spindle ID grinder
for precision components

With up to four spindles and the capability to carry out multiple grinding operations, the Bryant RU2 is a flexible ID grinding solution. Designed for small components up to 250mm, it is ideal for complex precision machining applications. Even better, with spindle speeds up to 120,000rpm and patented hydrostatic round bar in-feed system, it’s also highly productive.

Optimum productivity without compromising on precision

The Bryant RU2 was engineered from the ground up to accommodate today's ever-changing market. Our granite epoxy bed ensures exceptional thermal stability and the machine's linear motors and hydrostatic round bar in-feed system allow for optimum dimensional and geometric accuracy. Bryant is the most trusted name in today's highly demanding industries.
