Stacked component tapered bearing simulator device, the principles of which can be applied more broadly in such instrumentation as dynamometers and viscometers, can have a stator block with a sample receiving bore; a rotor complementary to the stator block bore extending axially into the bore to define a thin measuring gap, the rotor having a drive shaft extending axially upward from it; a motor, which can rotate in response to torque from a test sample present in the thin gap and which drives the shaft and rotor along a rotation axis; a part for sensing the torque, fixable to the motor, and connectable to a platform that is vertically adjustable by an elevator mechanism, which generally, externally bounds the axis of rotation of the motor, drive shaft, and rotor. Preferably, the elevator mechanism has a threaded arrangement with an anti-rotation device with a first set of threads residing with the platform, which is restrained from rotating by the anti-rotation device but is allowed to move vertically, and a second set of threads for mating with the first set of threads residing with at least one rotatable member separate from but threadedly engagable with the set of platform threads.
