摘要： A hand held machine tool intended for grinding and like operations, having an outer housing (10) lodging a pneumatic vane motor (11) by which a tool carrying spindle is rotated. At its forward end, the motor is supported in the housing by a resilient 0-ring (29) for absorbing radial vibrations arising in the spindle during work and a conical thrust ball bearing (30) for transferring axial load to the housing without restraining the radial resiliency provided by the O-ring. At its rear end, the motor is supported in the housing by a substantially non-resilient 0-ring (38), which means that the motor is apt to perform a pendular movement about its rear end when exposed to vibrations from the spindle.
