Kieninger is the oldest existing manufacturer of mechanical movements for floor, wall and mantel clocks in the world. Kieninger movements excel with a high level of design and manufacturing quality.
Manufacturing quality shows in every movement: All movement plates are made of a special brass alloy which is hard and has a tensile strength [Rm] of 520 N/mm2. The holes for the journals are reamed and smoothened after lacquering and then receive an oil sink.
Pinions are made of high-quality steel or stainless steel. Fast turning pinions are hardened. All journals are roller burnished in a special process. Some movements feature bronze-bushings and/or jewels in critical positions. The gears are made of a very tough and hard brass alloy with a tensile strength of 610 N/mm2.
A high level of corrosion protection for all components is assured. Brass components are pickled and receive a coat of clear lacquer. Steel components are made from stainless steel or receive a galvanic nickel coating. Each movement has a laser engraved serial number
