Deep groove ball bearing 6203ZZ

Description

1. Product Overview

Deep groove ball bearing 6203ZZ is a sealed, high-precision radial bearing designed for reliable rotational support in medium-duty industrial equipment. It provides low-friction performance for shafts and housings in motors, pumps, gearboxes, conveyors and auxiliary rotating systems. The key value proposition is long service life with minimal maintenance thanks to robust steel construction and metal-shield sealing that retains lubricant and excludes contaminants. As a standardized, high-volume component, the 6203ZZ is strategically important for reducing downtime, simplifying inventory (cross-compatible ISO dimensions), and lowering total cost of ownership across global industrial operations.

2. Key Specifications & Technical Characteristics

• Type: Deep groove ball bearing, double metal-shielded (ZZ)

• Bore diameter: 17 mm; Outer diameter: 40 mm; Width: 12 mm (ISO 15mm series 6203)

• Material (rings & balls): High-chromium bearing steel (commonly SAE 52100 / EN 1.3505)

• Cage: Stamped steel or polyamide (specify on order)

• Shielding/sealing: Metal shields (ZZ) both sides, non-contact or light-contact depending on variant

• Lubrication: Factory-filled with high-performance mineral or synthetic grease suitable for industrial bearings (specify grade on request)

• Tolerances: Standard ISO PN (P0) or available upgrades to P6/P5 on request for precision applications

• Dynamic load rating: Typical catalog range ~10–12 kN (specify exact rating per manufacturer batch)

• Static load rating: Typical catalog range ~4–5 kN (specify exact rating per manufacturer batch)

• Running speed: Up to typical limits per lubrication and precision class (refer to technical datasheet)

• Operating temperature range: Typically -30°C to +120°C with standard grease (extended ranges available with special lubricants)

• Surface finish & hardness: Hardened raceways (case hardness per standard bearing specs)

• Packaging options: Bulk in palletized boxes, protective inner sleeves, individually boxed units, or OEM-labelled drums; export cartons and shrink-wrap for sea freight

• Shelf life: Stable for multiple years if stored dry, clean, and within recommended temperature and humidity; re-inspect seals/lubrication after long storage

• Traceability: Batch/lot marking available on request for quality control and supply-chain traceability

3. Core Industrial Applications

• Primary industries: Industrial electric motors, HVAC systems, pumps, compressors, material handling (conveyors, rollers), machine tools, agricultural equipment, and automotive auxiliary systems.

• Specific use cases: Motor shaft bearings, idler rollers for conveyors, pump impeller supports, gearbox intermediate shafts, spindle support for light machine tooling.

• Why it outperforms alternatives: The deep groove geometry supports combined radial and moderate axial loads with low noise and vibration; metal shields (ZZ) retain grease while permitting higher speed than heavy-contact seals, reducing friction and energy loss. Standardized dimensions and widely available tolerance up-rates allow easy replacement and supply-chain consolidation—reducing downtime and spare-part complexity.

• Operational benefits: Improved energy efficiency via low rolling resistance, longer mean time between failures (MTBF) under normal operating conditions, and simplified maintenance protocols that lower lifecycle cost.

4. Competitive Advantages

• Quality consistency: Manufactured to international bearing standards with hardened raceways and controlled dimensional tolerances; batch testing and optional P-level certification reduce performance variance.

• Supply reliability: Readily available standardized SKU with scalable production, suitable for regular restocking and large tenders; BOM-friendly ISO sizing simplifies procurement.

• Logistics capability: Configured for bulk pallet and containerized export; protective packaging options for long-distance sea/rail shipments; support for JIT deliveries and scheduled replenishment.

• Price competitiveness: High-volume production and widespread sourcing options deliver attractive unit economics for bulk buys while maintaining technical performance.

• Sustainability: Long service life reduces replacement frequency and waste; options for recyclable packaging and compliance support for customer sustainability programs.

• Technical support & documentation: Full technical datasheets, CAD drawings, handling and storage guidance, grease selection recommendations, and failure-mode troubleshooting available on request; OEM compatibility matrices and shelf-life handling notes provided for industrial buyers.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20 MT

• Loading capacity (MT per container): Standard 20’ container up to ~20 MT (subject to packaging configuration and palletization); 40’ container up to ~24–26 MT depending on packing density and weight limits. Please confirm packaging selection to finalize exact loading plan.
