La Leonessa

What La Leonessa does

La Leonessa S.p.A. is an Italian, family-owned manufacturer of slewing rings (cuscinetti di base / base bearings) headquartered in Carpenedolo, Brescia, Italy, founded in 1971 by Ferdinando Pasotti and currently led by his daughter Gabriella Pasotti as President of both La Leonessa and the broader Leonessa Group. The company's core technology is a unified portfolio of slewing-ring bearings organized into six product families: slewing rings with external gear teeth, slewing rings with internal gear teeth, gearless slewing rings, flanged slewing rings, three-row roller slewing rings for high-load applications, and ball steering turntable bearings (ralle di sterzo a sfera). Variants include oil-bath-lubricated mixer slewing rings and corrosion-resistant slewing rings for water-treatment rakes. The company states that the Leonessa Group is the only European producer with a fully integrated supply chain running from raw steel bars through to finished slewing ring components, and the group also operates a manufacturing node in Yancheng, China via Leonessa Bearings Yancheng Co., Ltd.

La Leonessa serves industrial OEMs across six application segments: construction equipment (tower cranes, excavators, drilling equipment, concrete pumps, compacting machines, graders); lifting and handling (telehandlers, reach stackers, aerial platforms, forestry machines); process industry (pulp and paper, bottling, packaging, thickeners); marine (thrusters, deck cranes, winches, loading arms); power generation (wind turbines, solar panel tracking); and miscellaneous industrial uses (water treatment, planetary mixers, antennas). Named enterprise customers include Caterpillar Work Tools B.V. (CAT Excellence Award, 2017 best supplier) and Bomag GmbH (Class A supplier 2017, 2020, 2021), with intra-group supply to FAD Assali SPA for agricultural-trailer axles.

The company operates a sales-led B2B industrial go-to-market, with no publicly disclosed pricing, direct sales managed through named inside-sales contacts (Federica Franzoni, Sandra Franchini), a multilingual brochure website with downloadable product catalogs, and recurring trade-fair presence at Bauma Munich, Bauma China, and SIMA Paris. It holds UNI EN ISO 9001:2015 (quality management) and UNI EN ISO 14001:2015 (environmental management) certifications, implemented the EU Whistleblowing Directive via Italian d.lgs. n. 24/2023, and received CRIBIS Prime Company recognition in 2024 for commercial reliability. The company generates revenue through hardware sales of slewing-ring components under long-cycle OEM supply agreements rather than transactional or distributor-led channels.

Products and services

• Slewing Rings with External Gear (Cuscinetti di base con dentatura esterna) Slewing rings with external gear teeth designed for power transmission in heavy machinery applications. Used by industrial OEMs in construction and equipment requiring integrated gearing for rotational movement.
• Slewing Rings with Internal Gear (Cuscinetti di base con dentatura interna) Slewing rings with internal gear teeth for applications requiring internal gear integration. Used by OEMs that need compact gear geometry within the bearing envelope.
• Slewing Rings without Gear (Cuscinetti senza dentatura) Plain slewing rings for applications that do not require gear integration. Used as rotational movement components in industrial machinery.
• Flanged Slewing Rings (Cuscinetti di base flangiati) Flanged slewing rings for applications requiring flange mounting configurations with enhanced mounting stability for industrial equipment.
• 3-Row Roller Slewing Rings (Cuscinetti a 3 giri di rulli) Three-row roller slewing rings designed for high load capacity applications in heavy machinery such as wind turbines, port equipment, and large construction machinery.
• Steering Ball Bearings (Ralle di sterzo a sfera) Ball-type steering turntable bearings for steering mechanisms in heavy machinery such as telehandlers and industrial vehicles.

Broad incumbents

• Timken: Timken is a US-headquartered manufacturer of engineered bearings and power transmission products. Following its acquisition of the Rothe Erde slewing-ring business, it is a direct large-diameter bearing competitor with materially broader portfolio scale than La Leonessa.
• Liebherr: Liebherr is a major OEM of cranes, earthmoving equipment and other heavy machinery, with in-house large-diameter bearing and slewing-ring production that competes with both La Leonessa and with independent suppliers. As a vertical integrator it is a counterparty, a competitor, and an acquirer of slewing-ring specialists.
• NSK: NSK is a major Japanese bearing manufacturer producing a wide range of rolling-element bearings including large-size bearings for industrial and construction machinery. Serves the same OEM customer base as La Leonessa through its industrial-segment offering.
• NTN-SNR: NTN (and its European arm NTN-SNR) manufactures bearings for automotive, industrial and wind-energy applications, including slewing rings used in cranes and construction equipment. A broad incumbent with partial product overlap.
• SKF: SKF is the world's largest rolling-bearing manufacturer with broad coverage including slewing bearings used in wind, marine, construction and material-handling equipment. A broad incumbent serving similar end markets with substantially greater scale.
• Schaeffler (INA/FAG): Schaeffler manufactures rolling bearings across all major categories via its INA and FAG brands, including large-diameter and slewing bearings for construction, wind and industrial machinery. It is a much larger, more diversified competitor with overlapping capability in La Leonessa's core segment.
• JTEKT (Koyo): JTEKT (including its Koyo brand) is one of the world's largest bearing manufacturers, producing bearings for automotive, industrial and wind applications. It competes with La Leonessa in industrial slewing and large-diameter bearing categories.

Direct peers

• IMO (Regal Rexnord): IMO specializes in slewing rings and large gear-ring bearings for material handling, construction, marine and energy applications. The product positioning and customer set are highly comparable to La Leonessa's.
• Rothe Erde (Timken): Rothe Erde is a leading specialist in large-diameter antifriction bearings, including slewing rings for cranes, construction equipment, wind turbines and marine applications. Its product portfolio overlaps almost directly with La Leonessa's core slewing-ring offering, making it the closest comparable specialty competitor.
• Kaydon Bearings (SKF): Kaydon is a long-established specialist in thin-section and slewing bearings serving industrial, aerospace and construction-equipment markets. The product range and target applications closely overlap with La Leonessa's base-bearing portfolio.
