Mounting and fit
The R88M1M4K015CS2: Frame dimensions are 176 mm wide, 180 mm tall, and 180 mm deep — a compact cube that fits standard servo-mounting footprints. The 1S series shares a common bolt pattern across torque ratings, so if you are replacing a smaller unit, check the shaft keyway and pilot diameter against the existing coupling.
Listed as current production, so no last-time-buy pressure. We source these to order; lead time depends on the batch size and your delivery window. If you are freezing a BOM, this part is stable for the foreseeable future.
