What Leonhard Breitenbach does

Leonhard Breitenbach GmbH is a German roller (Walzen) manufacturer and contract machining specialist headquartered in Siegen-Trupbach, Germany, with 51-100 employees and a 160-year operating history dating to 1866. The company designs, casts, machines, and refurbishes precision rolls and large rotationally symmetrical components for industrial customers across five primary verticals: rubber and plastics, paper, battery foil, food, and feed, as well as horizontal applications in heavy machinery engineering, maritime, and amusement technology. Its product portfolio comprises ten core roll types (mixing rolls, calender rolls, thermo rolls, heat transfer and chill rolls, coating and doctor rolls, cracking and smooth rolls, flaking rolls, refiner rolls, precision rolls, and pistons for hydraulic presses) complemented by engineering, reconditioning, and contract machining services.

The company's technical platform rests on vertical integration from a company-owned roller foundry — featuring shell casting, gray cast iron static casting, and horizontal centrifugal casting — through to a modern CNC machine park that includes four CNC-controlled roll grinding machines (up to Ø2,500mm x 15,000mm), five-axis processing centers, a 12-meter deep hole drilling machine (solid Ø20-200mm, core Ø50-400mm, with counter-rotation capability), finish turning centers producing internal contours to 4,200mm depth, and hot grinding capability at operating temperatures up to 240°C. The firm also offers a chrome-free thermally sprayed tungsten carbide-cobalt (WC-Co) coating as a regulatory-friendly alternative to Chromium (VI). Operations are governed by a DIN EN ISO 9001:2015 quality management system certified by TÜV NORD.

Breitenbach operates a direct B2B enterprise field sales model with a network of sales engineers and country-specific representatives serving customers in more than 35 countries across EMEA, APAC, and the Americas. Revenue is generated through custom quotation-based pricing on project-specific orders and multi-year service contracts for roll manufacturing, contract machining, reconditioning/repair, and engineering services, with no public price list or e-commerce channel. The company markets via a multilingual (German, English, Chinese) website with downloadable technical resources, and is privately held with managing directors Dr. Jürgen Böhlemann (Technical) and André Groos (Commercial).

Core offering

Leonhard Breitenbach designs, manufactures, and refurbishes precision industrial rolls and large rotationally symmetrical components for the rubber and plastics, paper, battery foil, food, and feed industries. The company combines in-house casting (shell casting, gray cast iron, centrifugal casting) with CNC machining, hot grinding, and deep hole drilling capabilities for components up to 15,000 mm in length. Complementary services include contract machining, engineering/simulation during quotation, and roll reconditioning and repair.

Product overview

Breitenbach is a roller (Walzen) manufacturer and service specialist offering a comprehensive portfolio of precision-engineered rollers for industrial applications. The product line includes ten distinct roller types: Mixing Rolls (Mischwalzen), Calender Rolls (Kalanderwalzen), Thermo/Calender Rolls & Roll Shells, Heat Transfer/Chill & Polishing Rolls, Coating/Doctor Rolls & Printing Cylinders, Cracking & Smooth Rolls, Flaking Rolls, Refiner Rolls, Precision Rolls, and Pistons for Hydraulic Presses. The portfolio is complemented by contract machining services (turning, grinding, milling, deep hole drilling) and engineering/reconditioning services. The company serves five primary industries: rubber/plastics, paper, battery foil, food, and feed industries. Founded in 1866, the company operates from Siegen, Germany with a global sales network spanning over 35 countries.

Functional benefit

Products and services

• Mixing Rolls (Mischwalzen) Rolls used for the production of rubber and plastic mixtures; ensure uniform mixing of materials and increase homogeneity for rubber/plastic manufacturers.
• Calender Rolls (Kalanderwalzen) Rolls used for the production of plastic films and rubber sheets; require absolutely flawless surfaces to ensure best possible quality of end products.
• Thermo Rolls, Calender Rolls & Roll Shells Thermo rolls precision ground for the paper industry, enabling smallest thickness tolerances of paper webs with minimal temperature deviations on the surface.
• Heat Transfer & Chill Rolls, Polishing Rolls Rolls used for heating and cooling all types of web-shaped products in industrial web processing.
• Coating & Doctor Rolls, Printing Cylinders Rolls used for coating, painting, and impregnating plastic films, paper, textiles, and nonwovens.
• Cracking Rolls & Smooth Rolls Rolls used for grinding and breaking; wear resistance increases the efficiency of the grinding process and reduces maintenance, repair costs, and energy needs.
• Flaking Rolls (Flockierungswalzen) Rolls for hydrothermal and mechanical processing of grain, used in food and feed industries.
• Refiner Rolls (Refinerwalzen) Rolls used for the production of chocolate and similar refining applications; quality and melt of chocolate depend significantly on roll precision.
• Precision Rolls (Präzisionswalzen) Rolls requiring highest precision in run-out, form accuracy, and surface quality for applications where accuracy matters.
• Pistons for Hydraulic Presses (Kolben / hydraulische Pressen) Pistons for hydraulic presses made from shell cast iron or forged steel; used in metal forming and wood, plastic, and rubber processing; produced solid or hollow per customer specification.
• Contract Machining Services (Lohnbearbeitung) Comprehensive machining services including turning, finish turning, grinding, rough turning, deep hole drilling, and milling for large, round (rotationally symmetrical) components up to 12 meters in length.
• Engineering & Construction Services Design and development services using simulation software to calculate and configure roll designs during the quotation phase, developing individual and efficient solutions for each application.
• Roll Reconditioning & Repair Services Repair and refurbishment of rolls, shafts, and other components, including surface reclamation of barrels and bearing seats, journal replacement, and modernization of systems as an alternative to new acquisition.
