Deep groove ball bearing 6206 C3

Description

1. Product Overview

Deep groove ball bearing 6206 C3 is a high-precision rolling-element bearing engineered to support radial loads and moderate axial loads in high-speed rotary equipment. Commonly used in electric motors, gearboxes, pumps, compressors, and industrial drives, it delivers low friction, stable rotation, and predictable life under varied operating conditions. The C3 internal clearance provides controlled axial/radial play for thermal expansion and high-speed stability, reducing downtime risk and improving equipment throughput. This bearing is strategically important for industrial operations where predictable lifetime, energy efficiency, and minimal maintenance are critical to operating excellence and total cost of ownership.

2. Key Specifications & Technical Characteristics

• Bearing type: Deep groove ball bearing, single-row.

• Model designation: 6206 C3.

• Bore diameter: 30 mm.

• Outer diameter: 62 mm.

• Width: 16 mm.

• Internal clearance: C3 (greater than normal clearance for thermal and speed compensation).

• Dynamic load rating (approximate, typical range): 14–18 kN (confirm with vendor datasheet).

• Static load rating (approximate, typical range): 7–9 kN (confirm with vendor datasheet).

• Limiting speed (grease/oil, typical): up to 10,000–12,000 rpm depending on lubrication and operating conditions (confirm with vendor datasheet).

• Material / chemical composition: Bearing rings and balls — case-hardened chromium steel (commonly AISI 52100 / SAE 52100 or equivalent high-carbon chromium bearing steel). Cage material — pressed steel or brass (specify on order).

• Hardness: Typical through-case hardness for raceways and balls 60–64 HRC (quenched and tempered, vendor dependent).

• Surface finish: Precision-ground raceways and balls, low surface roughness to minimize friction.

• Tolerances: ISO/ABEC or DIN tolerance classes available on request; standard tolerance unless specified.

• Lubrication: Supplied unsealed or with sealed variants (ZZ, 2RS) and pre-greased options; grease type and fill configurable.

• Seals/shields: Options: open, ZZ (metal shield), 2RS (rubber seal), or custom seals for contamination resistance.

• Packaging: Industrial bulk boxes, individual polybags, wooden crates, or shrink-wrapped pallets.

• Shelf life: Indefinite under proper dry, cool storage; recommend installed within 3–5 years if pre-lubricated (verify grease specifications).

• Traceability: Heat lot and batch traceability available; material certificates (e.g., MTC) on request.

3. Core Industrial Applications

• Electric motors and generators: Provides stable rotation and long service life under continuous operation; C3 clearance mitigates thermal growth at high speed.

• Gearboxes and transmissions: Handles radial/limited axial loads with low friction for improved transmission efficiency and reduced heat.

• Pumps and compressors: Maintains shaft alignment and vibration control in rotating equipment to reduce leakage and wear.

• Machine tools and spindles: Suitable for moderate-speed spindles where clearance control improves thermal stability and machining accuracy.

• Automotive and heavy equipment ancillary systems: Reliable performance in alternators, water pumps, and accessory drives.
  Why it outperforms alternatives: The 6206 C3 combines standardized dimensions for interchangeability with C3 internal clearance for higher-speed stability and thermal compensation. High-grade bearing steel and precision finishing lower friction and extend fatigue life versus lower-grade or generic bearings, delivering lower lifecycle cost through longer bearing intervals and reduced unplanned maintenance.

4. Competitive Advantages

• Quality consistency: Manufactured to industry-standard metallurgy and precision grinding processes with batch traceability and available material certificates.

• Supply reliability: Produced in scalable batches with safety stock strategies to support continuous industrial procurement.

• Logistics capability: Bulk packing and containerized shipments supported; optimized for 20MT BULK loading and palletized distribution.

• Price competitiveness: Economies of scale in bulk procurement and configurable options (open vs sealed, cage material) allow buyers to balance cost vs performance.

• Sustainability: Long bearing life reduces replacement frequency and material waste; packaging options available with recycled/recyclable materials on request.

• Technical support: Engineering datasheets, installation guidelines, fitment tolerances, lubrication recommendations, and failure-analysis support available on request to accelerate application qualification.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20MT.

• Loading capacity (MT per container): Configured for standard 20 ft container up to approximately 20 MT bulk; 40 ft containers up to approximately 24–26 MT depending on packaging and palletization (confirm at order placement).
