Abstract
A hand held machine tool intended for grinding and like operations, having an outer housing containing a pneumatic vane motor by which a tool carrying spindle is rotated. At its forward end, the motor is supported in the housing by at least one resilient O-ring for absorbing radial vibrations arising in the spindle during work and a conical thrust ball bearing for transferring axial load to the housing without restraining the radial resiliency provided by the at least one O-ring. At its rear end, the motor is supported in the housing by a substantially non-resilient O-ring, which means that the motor is apt to perform a pendular movement about its rear end when exposed to vibrations from the spindle.
