Kugel- und Rollenlagerwerk Leipzig

What Kugel- und Rollenlagerwerk Leipzig does

Kugel- und Rollenlagerwerk Leipzig GmbH (KRW) is a Leipzig-based, privately held German manufacturer of customized rolling bearings, founded in 1904 and operating as a Gesellschaft mit beschränkter Haftung (GmbH) under three managing directors: Andreas Fitzner, Andreas Poltsch, and Nico Taubert. The company produces over 9,000 different rolling bearing types annually, with diameters ranging from 50mm to 2,500mm, covering ball bearings (deep groove, angular contact, four-point contact, spindle, self-aligning, thrust), roller bearings (cylindrical, tapered, spherical, barrel, axial), bearing housings, components (L-section rings, rolling elements, cage assemblies, thrust bearing washers), and rolling bearing accessories. Application-optimized product lines include the ROTAB sub-brand for rotary table bearings (including the DBS series for direct drives), current-insulating bearings rated to 3,000V DC for electric motors with frequency converters, hybrid bearings with ceramic rolling elements, ACB self-aligning cylindrical roller bearings, cylindrical roller wheelset bearings for rail, support roller bearings for rolling mills, coated bearings for corrosive environments, and bearings manufactured from special steels and stainless materials. High-precision offerings reach concentricity accuracies of a few micrometers, with special precision spherical roller bearings achieving 3 micrometers total concentricity.

The company serves eight industrial verticals: railway and transportation, industrial and large gearboxes, motors/generators/turbines, offshore technologies, paper and plastics processing, raw material extraction and processing, rolling mills, and machine tools and processing machines. Named or category-disclosed customers include Deutsche Bahn (Q1 supplier with Herstellerbezogene Produktqualifikation (HPQ) certification for over 10 years supplying safety-critical wheelset bearings), Hüttenwerke Krupp Mannesmann (rolling mill bearings), wind turbine manufacturers (development partner for gearbox bearings), and "world's leading machine tool manufacturers." KRW holds ISO 9001 (quality management) and ISO 50001 (energy management) certifications, and its wheelset bearings meet EN 12080 Class 1 and DIN 5412-11.

KRW's revenue model is hardware sales of standard and customized rolling bearings complemented by a service portfolio: selection/dimensioning engineering, online fitting and bearing-clearance calculators, diagnosis and damage analysis (visual inspection, lubricant analysis, metallography, metrological and SEM investigation), assembly support, reconditioning (up to 60% cost savings and 50% shorter delivery versus new bearings), training courses, and contract manufacturing (Lohnfertigung). Distribution is direct B2B sales plus a specialist dealer network, with a global reach claim supported by a four-language website (German, English, Russian, Chinese) and trade show presence at CCMT and InnoTrans. The company runs an in-house dual vocational training system with European Social Fund support and maintains no public revenue, no external shareholders, and no disclosed M&A or capital-raising activity.
