The Bearing 6306 is a deep groove ball bearing widely used in automotive, industrial, and mechanical applications. Below is a concise overview based on available information:

Specifications:

Type: Single-row deep groove ball bearing.

• Part Number: 6306 (suffixes like 2RS, ZZ, or 2Z indicate seals/shields, e.g., 6306-2RS for rubber seals, 6306-ZZ for metal shields).
• Material: Typically chrome steel (Gcr15); stainless steel or ceramic available for specialized uses.
• Load Ratings (approximate, varies by manufacturer):
  • Dynamic Load: ~26,700 N
  • Static Load: ~15,000 N
• Speed Limits (approximate):
  • Grease Lubrication: ~9,000–11,000 RPM
  • Oil Lubrication: ~12,000–14,000 RPM
• Cage: Usually steel; nylon or brass for high-speed or specific applications.
• Sealing Options:
  • Open (no seals/shields)
  • 2RS (double rubber seals for dust/water resistance)
  • ZZ/2Z (double metal shields for lower friction)
• Clearance: Standard (C0), with C3 (greater clearance) for high-speed or high-temperature applications.

Applications:

• Automotive: Used in alternators, starters, water pumps, or wheel hubs.
• Industrial: Common in electric motors, pumps, fans, and conveyors.
• Machinery: Found in agricultural equipment, power tools, and HVAC systems.
• Other: Bicycles, motorcycles, or appliances (sealed versions like 6306-2RS are popular).

Key Features:

• Supports radial and moderate axial loads in both directions.
• Low friction, suitable for high-speed operations.
• Durable, especially with sealed/shielded versions for low maintenance.
• Standardized size ensures wide availability and affordability.
