What SIBO does

SIBO (S.I.BO. srl – Società Italiana Boccole) is an Italian manufacturer of hardened steel bushings founded in 1979 and headquartered in Calderara di Reno, near Bologna. The company produces over 2 million bushings per year from a 6,200 sqm production facility on a 23,000 sqm industrial site, serving OEMs of construction and earthmoving equipment, agricultural machinery, mining equipment, hydraulic cylinders, and aerial work platforms, as well as the aftermarket replacement parts market.

The product portfolio is built around a proprietary metallurgical and heat-treatment platform. Core lines include STD Line (standard cementation-hardened bushings at HRC 58-62 with 0.8-1mm case depth), EVO (differentiated variants with special surface treatments and internal grooving for extended lubrication intervals up to 550 hours), RAW (thermo-chemically treated bushings with corrosion resistance), Jolly (oversized repair bushings for quick field replacement), flanged, and brake/buffer bushings, plus custom designs manufactured to customer specifications. SIBO holds controlled-chemistry steel alloys to its own specifications, operates an in-house metallographic laboratory with four testing benches, and maintains an 8+ year R&D collaboration with the University of Bologna's Department of Mechanical and Metallurgical Chemical Engineering. The company is certified to ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018, holds 100% Made in Italy certification, and is REACH compliant.

SIBO's revenue model combines hardware sales of both standard and custom bushings with design and prototyping services for OEM customers. Pricing is quote-based across all channels. Distribution is dual-track: direct field sales to major OEM accounts globally, and a dealer/reseller network — actively being expanded — for the aftermarket replacement parts segment. The company maintains a stock of more than 250,000 pieces for 2-3 day delivery and over 400 tons of raw material, and markets itself through international trade shows (Bauma, EIMA, Intermat, Samoter, IFAT, SMOPYC, Euro Mine Expo), a multilingual website (Italian, English, French, German), and an active social and content presence.

Core offering

SIBO produces hardened steel bushings (boccole) for OEM and aftermarket customers in excavators, earthmoving, agriculture, and hydraulic cylinder applications. The offering includes standardized product lines (STD, EVO, RAW, Jolly, Flanged, Brake) plus custom-designed bushings manufactured to client specifications. All production is conducted at the company's Calderara di Reno facility with proprietary cementation heat treatment and metallurgical R&D.

Product overview

SIBO (Società Italiana Boccole) is a manufacturer of hardened steel bushings, producing over 2 million bushings annually from its facility in Calderara di Reno, Italy. The product portfolio consists of the core product lines: Standard STD Line (cementation-hardened standard bushings), EVO Line (innovative bushings with enhanced durability and lower friction), RAW Line (cost-effective bushings with corrosion resistance), Flanged Bushings (for radial and axial loads), Jolly Repair Bushings (oversized for quick replacement), and Brake Bushings/Ammortizzatori (for hydraulic cylinder braking). Additionally, SIBO offers custom bushings manufactured to customer specifications. All products are 100% Made in Italy with in-house heat treatment capabilities and R&D laboratory support.

Functional benefit

Brands

• STD Line TM: Standard line of cementated bushings with SIBO tolerances (outer Ø u6 – inner Ø C8), subjected to Carburizing Quenching and Tempering heat treatments with 0.8-1mm carburizing depth, HRC 58-62 hardness after grinding.
• EVO Bushings TM
• RAW Bushings TM
• Jolly Bushings TM

Products and services

• STD Line Cementated Bushings (Boccole Cementate Standard STD Line) Standard cementation-hardened steel bushings with SIBO tolerances (outer diameter u6, inner diameter C8), subjected to cementation hardening and tempering heat treatment with 0.8-1mm cementation depth and HRC 58-62 hardness after grinding. Designed for OEM and aftermarket applications requiring wear resistance and anti-seizure performance in low-speed, high-pressure articulation systems.
• EVO Bushings (Boccole EVO) Innovative steel bushings with greater durability and lower friction coefficient, combining specific heat treatments with special internal grooves (ragnatura) for excellent grease distribution and continuous lubrication. Suitable for high-specific loads and positions where lubrication access is difficult, serving OEMs in construction, agricultural and hydraulic equipment.
• RAW Bushings (Boccole RAW) Cost-effective cementated steel bushings for customers seeking quality with simpler performance characteristics than STD Line. Features specific thermochemical treatment in ammonia gas atmosphere and cementing gas, providing high surface hardness, good abrasion resistance and excellent corrosion resistance. Targeted at OEMs and aftermarket buyers prioritizing value and corrosion performance.
• Jolly Repair Bushings (Boccole Jolly) Oversized repair bushings designed for rapid field replacement. Inner surface hardened to HRC 58-62 and ground; outer surface at HRC 40-42 can be machined to required diameter. Thicker wall (>7.5mm) adapts to worn seats without welding or complex repairs, providing a quick aftermarket solution for worn articulation points.
• Flanged Bushings (Boccole Flangiate a Battuta) Flanged steel bushings equipped with a collar capable of bearing radial and axial loads. Used in applications requiring maximum precision and resistance, particularly in excavator joints, buckets, hydraulic clamps and construction/demolition equipment.
• Brake Bushings / Shock Absorbers (Boccole Freno / Ammortizzatori) Brake bushings for hydraulic cylinders that enable gradual braking of the cylinder rod, preventing sudden stops and jerks. Manufactured from cementation steel to avoid sudden breakage, with precision machining capabilities for inclined milling, frontal milling, plane grinding and threading. Sold to hydraulic cylinder manufacturers and rebuilders.
• Custom Bushings (Boccole a Disegno / Esecuzione Speciale) Custom-designed bushings manufactured to customer specifications with special grooving patterns of various depths. Not kept in stock; produced upon request. Available variants include smooth, grooved (ragnata), internal groove, groove with holes, and external groove with holes. Targets OEMs requiring tailored bushing designs for unique articulation or hydraulic applications.
