Deep groove ball bearing 6205-2RS

Description

1. Product Overview

The Deep Groove Ball Bearing 6205-2RS is a precision-engineered radial bearing featuring sealed contact rubber shields on both sides, designed for high-load, moderate-speed rotary applications. It provides reliable shaft support, low friction, and long operational life in industrial equipment such as electric motors, pumps, gearboxes, and conveyor drives. Its primary value proposition is consistent performance under mixed radial/axial loads with dust and moisture ingress protection, reducing maintenance frequency and unplanned downtime. For strategic procurement, the 6205-2RS is a cost-effective, widely standardized component that simplifies inventory management while supporting equipment uptime and predictable lifecycle costs.

2. Key Specifications & Technical Characteristics

• Type: Deep groove ball bearing, single-row, sealed (2RS — rubber seals both sides)

• Outer diameter: 52 mm

• Width: 15 mm

• Dynamic load rating (typical range): ~13.75 kN (manufacturer-specific)

• Static load rating (typical range): ~7.3 kN (manufacturer-specific)

• Seals: NBR/ rubber contact seals 2RS (prevents dust and liquid ingress)

• Cage material: Pressed steel (or nylon/polyamide option on request)

• Balls: Chrome steel (AISI 52100) standard; stainless steel (AISI 440C) option available for corrosive environments

• Ring material: High-carbon chromium steel (commonly 100Cr6/SAE 52100)

• Hardness: Typical raceway hardness 58–64 HRC after heat treatment (manufacturer-dependent)

• Lubrication: Factory-filled with high-performance grease (temperature range and grease spec customizable)

• Radial clearance: Standard ISO clearance (C0/C2/C3 available on request)

• Running temperature range: Typically -30°C to +120°C (dependent on seal and grease selection)

• Corrosion protection: Standard chromium steel; additional coatings (zinc, phosphate, or stainless variants) available

• Tolerances: Standard ISO P0; higher precision classes (P6/P5) provided on request

• Packaging options: Industrial bulk coils/boxes, wooden crates, or palletized cartons; inner boxes with desiccant and anti-corrosion paper available for export

• Shelf life: Indefinite when stored sealed in original packaging under recommended conditions (dry, 5–25°C); recommended inspection if stored >5 years

• Traceability: Batch and heat-number traceability available on request for quality audits

3. Core Industrial Applications

• Electric motors and generators: Supports rotor shafts with low friction and extended service intervals; sealed design minimizes contamination-related failures.

• Pumps and compressors: Handles radial and moderate axial loads in fluid-handling equipment; seals protect lubricant integrity.

• Gearboxes and reducers: Standardized fit for transitional shafts, providing durable rolling contact under cyclic loading.

• Material handling and conveyors: Low maintenance option for idlers, pulleys, and drive units operating in dusty or mildly wet environments.

• Machine tools and industrial automation: Suitable for rotary joints, spindles with lower precision requirements, and actuator assemblies where reliability and uptime matter.
  Why it outperforms alternatives: Standardization ensures interchangeability and competitive pricing; sealed construction lowers lifecycle maintenance costs versus open bearings; high-quality steel and precise heat treatment deliver superior fatigue life and load capacity compared with low-grade imports.

4. Competitive Advantages

• Quality consistency: Manufactured to international ISO/ABMA standards with hardened raceways and controlled tolerances for predictable lifecycle performance.

• Supply reliability: Production and stock planning for bulk orders with regular replenishment windows and documented lead times to support MRO and project schedules.

• Logistics capability: Export-ready packaging, consolidated palletization, and containerized shipping coordination for bulk 20 MT loads; local distribution options available to shorten lead times.

• Price competitiveness: Economies of scale on standard 6205-2RS units enable low unit cost without compromising materials or heat-treatment quality.

• Sustainability: Long service life reduces replacement frequency and material consumption; options for recyclable packaging and low-VOC lubricants available.

• Technical support and documentation: Full product datasheets, dimensional drawings, lubrication recommendations, installation guidelines, and batch traceability certificates provided; engineering support for fit, clearance selection, and failure analysis on request.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20 MT

• Loading capacity (MT per container): Typical 20-foot container capacity for packaged 6205-2RS bearings (palletized) — approximately 20 MT, depending on packaging configuration and cushioning.

• Lead times: Standard stock fulfillment for MOQ subject to confirmation; expedited manufacturing options available for confirmed long-term contracts.

• Shipping and export: FOB/CIF terms negotiable; export packaging meets international handling standards with rust inhibition and moisture control.

• After-sales: Quality claims handled under agreed warranty terms; spare-part replenishment programs and blanket purchase agreements supported.
