Deep Groove Ball Bearing 6205 Type

Description

1. Product Overview

Deep Groove Ball Bearing 6205 Type is a precision-engineered radial bearing designed to support moderate radial and axial loads while delivering low-friction rotation and extended service life. Primarily used in rotating machinery—motors, pumps, gearboxes, conveyors, and industrial fans—this bearing provides reliable shaft support and accurate alignment under continuous operation. Its key value proposition is a balanced combination of high load capacity, low maintenance requirements, and broad compatibility with standard industrial housings and shafts. Strategically, the 6205 type serves as a commodity-critical component across manufacturing and process industries, minimizing downtime and enabling predictable lifecycle costs in large-scale operations.

2. Key Specifications & Technical Characteristics

• Type: Deep groove ball bearing, single-row, open or sealed variants available.

• Inner diameter (bore): 25 mm; Outer diameter: 52 mm; Width: 15 mm (standard 6205 dimensions).

• Material: High-carbon chromium bearing steel (AISI 52100 / equivalent), rings and balls; stainless steel options (AISI 440C) available on request.

• Cage: Pressed steel (standard), polymer (nylon) or brass cages available as alternatives.

• Hardness: Bearing raceways typical hardness HRC 60–66 (case-hardened/through-hardened per spec).

• Surface finish: Precision-ground raceways and balls, Ra per customer spec (typical 0.2–0.4 μm).

• Tolerances: ISO/ABEC/JIS tolerance classes available (standard P0, precision P6/P5 upon request).

• Load ratings (typical): Dynamic radial load rating Cr ≈ 11.2 kN; Static radial load rating Cor ≈ 6.45 kN (manufacturer-specific).

• Speed rating: Up to 9,000–12,000 rpm depending on lubrication, clearance, and sealing.

• Seals/Shields: Open, 2RS (rubber seals), ZZ (metal shields) options for contamination control.

• Lubrication: Pre-greased (industrial lithium or synthetic grease), or grease-free for customer lubrication.

• Operating temperature range: -30 °C to +120 °C (standard greases); extended-temperature greases expand range.

• Corrosion resistance: Standard with protective coatings; stainless options for corrosive environments.

• Packaging: Individual polybag and boxed, bulk carton, wooden crates for palletized loads, or 20MT bulk drums/containers per customer requirement.

• Shelf life: Indefinite under dry, clean storage; recommended rotation if pre-greased stored >24 months.

• Traceability: Batch and heat-number traceability, material certificates (COA) available.

3. Core Industrial Applications

• Electric motors and generators: Acts as primary radial support enabling smooth high-speed rotation and reduced energy loss.

• Industrial pumps and compressors: Maintains shaft alignment under combined radial/axial loads, improving seal life and reducing leakage.

• Gearboxes and reducers: Provides low-friction rolling elements for torque transmission with predictable wear profiles.

• Material handling and conveyor systems: Ensures continuous operation under variable loads and contamination exposure.

• HVAC and fans: Delivers quiet operation and long maintenance intervals in high-cycling systems.
  Why it outperforms alternatives: The 6205 deep groove design offers a superior balance of load capacity versus size, lower running friction than plain bearings, and simpler installation/service than angular-contact bearings. Standardization across global OEMs reduces sourcing complexity, and available sealed variants lower lifecycle maintenance and contamination-related failures. These factors translate into higher equipment uptime, lower total cost of ownership (TCO), and predictable replacement intervals.

4. Competitive Advantages

• Quality consistency: Manufactured to strict metallurgical and dimensional tolerances with in-process inspection and final QA testing.

• Supply reliability: High-volume production and regional stocking options to support industrial MRO programs and OEM contracts.

• Logistics capability: Containerized shipping solutions, palletized bulk, and vendor-managed inventory options to meet just-in-time demands.

• Price competitiveness: Commodity-scale sourcing combined with tiered pricing for volume buyers and long-term contracts.

• Sustainability: Longer bearing life and reduced energy losses contribute to lower lifetime emissions; recyclable steel construction.

• Technical support: Detailed product datasheets, installation and lubrication guides, bearing selection assistance, and failure-analysis support available upon request.
  Positioning: Procurement of 6205 bearings should be treated as a strategic sourcing decision—standardized spec, documented traceability, and supplier SLAs reduce operational risk.

5. Commercial & Supply Information

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

• Loading capacity (MT per container): Typical 20-foot container capacity up to 20 MT (subject to packaging density and local export regulations); 40-foot container capacity up to ~26–28 MT.

• Lead times: Standard stock items available for prompt dispatch; larger bespoke or precision tolerance orders subject to manufacturer lead times (confirm at time of purchase).

• Documentation: Certificates of analysis, material certificates, and conformity documentation provided with bulk shipments on request.
