Sill Bearing
Sill Bearing
Engineered specifically to support the structural, maritime, automotive, and industrial assemblies within the Naples economic cluster.
The metropolitan area of Naples (Campania region, Southern Italy) represents one of the most vital aerospace, maritime, packaging, and automotive manufacturing clusters in Southern Europe. From aerospace defense networks located in Pomigliano d'Arco and Caserta to the food processing and packaging machinery clusters running through Salerno and Naples, the demand for highly reliable mechanical components remains exceptional.
Within this ecosystem, the 6200 series deep groove ball bearing serves as a fundamental building block. Characterized by its balanced radial and axial load capabilities, low torque, and exceptional stability under high-speed rotations, the series is widely integrated into electric motors, automated sorting belts, marine pump units, and material handling systems operating across Naples' active ports.
"Procurement directors in Campania require more than off-the-shelf components. They demand certified GCr15 high-carbon chromium steel structures, micro-ground raceways with custom C3/C4 clearance configurations, and compliance parameters that align directly with EU directives."
SILL BEARING FACTORY is located in the beautiful and affluent place named Hangzhou Bay New Zone. This key logistics hub is not only close to the two biggest ports of China—Shanghai port and Ningbo Port, but also adjacent to the Hangzhou—Ningbo Expressway, 329 State Line, and the Hangzhou-Ningbo Railway Line. The localized logistics yield excellent transportation advantages: it takes only about 90 minutes to access either Hangzhou Xiaoshan Airport or Ningbo Lishe Airport, speeding up overseas delivery cycles to Italy and greater Europe.
To expand our manufacturing capability and meet the growing global sourcing needs for 6200 series bearings, our new factory, Anhui TOPB IMP.&EXP. Co., Ltd., is under construction. Once fully operational, our annual production capacity will increase by $20 million, allowing us to support larger-scale rolling forecasts and stock-management agreements for Italian contract manufacturers.
Under our proprietary brands, SILL and NETB, we specialize in designing, studying, and producing Deep Groove Ball Bearings (ranging from φ 4mm to φ 120mm), Tapered Roller Bearings, and non-standard custom bearings. We strictly utilize superior bearing steel "GCr15", and apply meticulous heat treatment to achieve optimal hardness and structural stability.
How SILL guarantees a 100% acceptance rate for demanding applications, ensuring zero-defect installation for Naples manufacturing partners.
Spectroscopic analysis and microstructure verification of incoming GCr15 high-carbon chromium steel bars and tubes to prevent inclusions or structural defects.
Machinists and grinding operator tests utilizing digital micrometers and roundness measuring units at every step of collar processing.
100% of finished assemblies are tested via automated testing machines for radial clearance, inner/outer ring alignment, and seal integrity.
Random batch testing to confirm compliance with ISO-2859-1 standards. Dynamic testing under load to confirm target running hours.
Detailed rust preventive oil application checking, packaging stability evaluation, and validation of custom barcoding before dispatch.
High-quality design classifications, optimized to fulfill mechanical engineering needs in modern plants.
The 6200 series deep groove ball bearing belongs to the light-duty series, featuring a larger ball diameter compared to the ultra-light 6000 series, which provides a significantly higher radial load rating. This makes them ideal for environments where compact space must be combined with high mechanical resilience, typical of the gearboxes and processing equipment found in Naples' regional packaging lines.
| Bearing Designation | Bore Diameter (d) | Outer Diameter (D) | Width (B) | Basic Dynamic Load Rating (Cr) | Basic Static Load Rating (Cor) | Limiting Speed (Grease) |
|---|---|---|---|---|---|---|
| 6200 | 10 mm | 30 mm | 9 mm | 5.1 kN | 2.39 kN | 22,000 r/min |
| 6201 | 12 mm | 32 mm | 10 mm | 6.89 kN | 3.1 kN | 20,000 r/min |
| 6202 | 15 mm | 35 mm | 11 mm | 7.65 kN | 3.72 kN | 17,000 r/min |
| 6203 | 17 mm | 40 mm | 12 mm | 9.56 kN | 4.75 kN | 15,000 r/min |
| 6204 | 20 mm | 47 mm | 14 mm | 12.8 kN | 6.65 kN | 13,000 r/min |
| 6205 | 25 mm | 52 mm | 15 mm | 14.0 kN | 7.85 kN | 11,000 r/min |
When sourcing 6200 series bearings, engineers must consider sealing profiles (Open, ZZ - metal shields, 2RS - rubber lip seals) and internal clearances (CN for standard applications, C3/C4 for high thermal expansions like motor housings or hot zone packaging machinery). At SILL, our engineering team assists procurement managers in Campania to choose the precise combination of grease filling, seal type, and clearance to maximize the L10 service life of the machine.
Original series selections engineered with GCr15 high-carbon chromium steel for high performance.
A look into our grinding and testing facilities where high-quality bearing standards are maintained.
Our company values brand building, and the SILL brand is recognized for its low noise, low vibration, low friction, high accuracy, highly sealed functions, long service life, and lack of abnormal sound. Our production processes utilize high-frequency induction hardening of raceways and super-finishing to ensure the surface roughness (Ra) matches the standards required by high-precision applications.
We supply bearings for household appliances, micro motors, electric fans, motorcycles, automobiles, medical instruments, sports machinery, textiles, and agricultural machinery. Our components are exported globally to countries such as the U.S., Brazil, Switzerland, the United Arab Emirates, Iran, Turkey, Pakistan, Malaysia, Bangladesh, Egypt, Nigeria, and regional supply hubs like Hong Kong and Taiwan.
How SILL is aligning bearing production to support digitalization, automation, and green energy initiatives.
Developing hybrid ceramic bearings (incorporating silicon nitride Si3N4 balls) to provide electrical insulation and friction reduction under high-frequency electrical motor operations—ideal for modern EV components and automated industrial packaging systems in Italy.
Optimizing seal geometries (non-contact labyrinth designs) and advanced synthetic grease formulas to reduce torque loss by 15%, aligning with the European Union's carbon reduction guidelines for manufacturing plants.
Exploring sensor integration inside bearing housings for predictive maintenance, tracking parameters like speed, temperature, and vibration in real time to prevent costly downtime on automated production lines.
Expert answers regarding the application, custom manufacturing, and ordering of 6200 series bearings in the Naples market.
GCr15 is a high-carbon chromium bearing steel known for its exceptional wear resistance, structural stability, and fatigue resistance. After undergoing heat treatment and oil quenching, it achieves a hardness of HRC 60 to 65, which is necessary to withstand the continuous rolling stresses typical of industrial machinery operations.
We implement a strict 5-stage inspection procedure. This includes checking raw materials, testing at the machine by operators, full component verification by inspectors, random sampling by chief quality controllers, and a final check before packaging. This systematic verification process ensures a 100% acceptance rate.
Yes. Through our engineering division, we offer customization services for dimensions, seal designs, C3/C4 clearance options, and special lubricants. We provide CAD and technical drawing approvals before starting mass production to ensure all specifications align with your application requirements.
Due to our close proximity to Shanghai Port and Ningbo Port, we can optimize ocean freight routes. For Naples-based clients, container shipping typically takes 30 to 45 days. We also offer air freight services for urgent sample evaluations or critical spare parts replacement.
