Lohmann + Stoterfoht, founded in 1884 in Berlin, is a company of the Rexroth Group. This yields numerous advantages through inter-company research and cooperation within such a large-scale organization. Trend-setting innovations have emerged from working closely together. Combining hydraulic and mechanical systems has produced many transmission-engineering highlights with a vast development potential still ahead. Certification to DIN ISO 9001 has of course been obtained. These are achievements we can be proud of.

Being experts in transmission technology is our duty to keep things moving. New challenges that come up must be addressed, existing and new markets served. With the innovative spirit of its staff and backed by the strength of the Rexroth Group Lohmann + Stolterfoht will remain in the top performer class in its line of business.
