Deep groove ball bearing 6310 C3

Description

1. Product Overview

Deep groove ball bearing 6310 C3 is a single-row, deep-groove radial ball bearing engineered for medium-to-high radial loads and moderate axial loads in both directions. It is primarily used to support rotating shafts in industrial machinery—motors, gearboxes, pumps, conveyors, and electric drives—providing low-friction, high-reliability rotation. The 6310 C3 designation indicates a larger bore-to-width ratio for compact designs and a C3 internal radial clearance that ensures optimal performance under thermal expansion and high-speed operation. As a widely standardized bearing size with proven lifecycle performance, it is a strategically important commodity for maintaining uptime across heavy industries and integrated supply chains.

2. Key Specifications & Technical Characteristics

• Material: Bearing steel (commonly AISI 52100 / ISO 683-17 / equivalent high-carbon chromium steel)

• Heat treatment: Through-hardened bearing rings and hardened raceways (typical)

• Balls: Chrome steel (AISI 52100) precision-ground balls

• Cage: Pressed steel cage (standard); alternative cages available (brass, polyamide) on request

• Tolerances: P0 (standard) or higher precision classes available on request

• Lubrication: Pre-lubricated options (mineral grease) or supplied un-lubricated for user-specific greasing

• Sealing: Open (standard); seals/shields available (2RS, ZZ) as configurable options

• Operating temperature range: typical -30°C to +120°C (depends on lubricant and seal selection)

• Rotational speed rating: refer to datasheet; high-speed variants available with optimized internal geometry

• Packaging options: Individual box; bulk box; palletized crates; wooden/steel container packaging for export

• Shelf life: Indefinite if stored dry, clean, at stable temperature and humidity; recommended storage ≤ 50% relative humidity, away from corrosive environments

3. Core Industrial Applications

• Primary industries: Heavy machinery; electric motor manufacturing; gearboxes and drive systems; mining equipment; pulp & paper; steel mills; HVAC and centrifugal pump manufacturers; material handling and conveyors; OEMs for industrial equipment.

• Operational use cases:

  • Motor and generator shaft support, where low friction and long service life reduce energy consumption and downtime.

  • Gearbox intermediate and output shafts, providing radial load support with moderate axial tolerance.

  • Pump and fan bearings requiring stable clearance under thermal cycling (C3 clearance prevents preload under expansion).

  • Conveyor rollers and idlers where standardized sizing simplifies global sourcing and spares management.

• Performance vs alternatives:

  • Compared with plain bearings, deep groove ball bearings offer lower friction, higher precision, and easier maintenance.

  • Versus angular-contact bearings for similar sizes, they provide simpler mountings and bidirectional axial load capacity without complex preloads.

  • The C3 clearance variant outperforms standard-clearance bearings in high-temperature or high-speed conditions by preventing excessive preload during expansion.

4. Competitive Advantages

• Quality consistency: Manufactured to ISO/ABMA standards with hardened raceways, precision grinding, and strict material traceability for repeatable service life.

• Supply reliability: Standardized global SKU with established production capacity and dependable lead times; suitable for long-term contracts and MRO stocking.

• Logistics capability: Configurable export packaging, palletization, and container loading processes to support cross-border bulk shipments and industrial procurement cycles.

• Price competitiveness: Commodity size benefits from economies of scale; competitive pricing when procured in bulk (MOQ terms apply).

• Sustainability: Long service life reduces replacement frequency and lifecycle environmental footprint; recyclable bearing steels and reduced lubricant waste with appropriate maintenance.

• Technical support: Comprehensive technical documentation (dimensional drawings, load ratings, lubrication recommendations, mounting/dismounting procedures) and application engineering guidance available to optimize installation and lifecycle cost.

• Strategic sourcing position: Standard form-factor and broad OEM acceptance make this bearing a low-risk component for global supply chains and MRO programs.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20MT

• Loading capacity (MT per container): Typical 20-foot container load depends on packaging density; estimated full-container load approximately 20–22 MT (confirm exact packing plan with supplier/logistics partner)

• Lead times: Subject to contract and current production schedules; expedited production available for prioritized orders (confirm at time of purchase)

• Packaging: Bulk palletized or boxed packing with corrosion inhibitors and desiccants for export; customizable labeling and documentation for buyer compliance

• Documentation: Mill certificates, material traceability, inspection reports, and recommended maintenance instructions available on request
