Product Description

7226AC Precision Angular Contact Bearings High Load Heavy Duty Ball Bearings

Product Overview

7226AC Angular Contact Ball Bearing: High-Load, Heavy-Duty Performance

Basic Parameters

Bore diameter (d): 130mm
Outer diameter (D): 230mm
Width (B): 40mm
Contact angle: 25° (suffix "AC" denotes standard angle)
Weight: Approximately 7.26kg (16.0 lbs)
Structure: Single-row, non-separable design with inner/outer rings and ball assembly
Cage options: Brass solid cage (standard for high-speed applications) or pressed steel (J steel stamping) for heavy loads

Core Performance Specifications

Load Capacity

Dynamic load rating (Cr): 177~186kN (typical range)
Static load rating (C0r): 180~193kN (typical range)
Material: GCr15/SUJ2 high-carbon chromium bearing steel (HRC58-62), with optional ceramic (Si3N4 balls) or stainless steel (SUS440C) variants for corrosive environments

Speed & Precision

Limiting speed:
- Grease-lubricated: 2,400~2,800rpm (typical range)
- Oil-lubricated: 3,200~3,957rpm (optimized for high-speed industrial drives)
Precision class: Standard P0 (customizable to P5/P4 for machine tool spindles)

Technical Features

Axial-radial load capability: Supports combined radial loads and unidirectional axial thrust. Paired installation (e.g., back-to-back) required for bidirectional loads
Heat dissipation design: Enhanced raceway geometry reduces friction during continuous operation at high loads

Structural & Environmental Adaptability

Tolerance compatibility:
- Shaft: H7/k6
- Housing: J7
Temperature range:
- Standard: -20°C to 120°C
- High-temperature variants: Up to 300°C with ceramic components and special grease
Sealing options:
- Open design (standard)
- Optional 2RS (rubber seals) or ZZ (metal shields) for dust/moisture protection

Typical Applications

Industrial Machinery

Heavy-duty gearboxes: Handles radial loads in mining and construction equipment drivetrains
Wind turbine main shafts: Supports high torque and axial thrust in 2MW+ wind generators
Large-scale pumps/compressors: Resists fluid pressure in oil/gas or water treatment systems

Transportation

Commercial vehicle axles: Used in truck differentials for high-torque applications
Marine propulsion systems: Corrosion-resistant variants (SUS440C) for shipboard gearboxes

Precision Equipment

CNC machine tool spindles: Provides rigidity for heavy milling operations (custom P4 precision)
Robotic actuators: Enables precise positioning in industrial robots handling payloads >500kg

Maintenance & Lubrication Guidelines

Lubrication

Grease: Lithium-based grease (NLGI 2) with 15%-20% cavity filling; synthetic polyurea grease recommended for temperatures >120°C
Oil: Circulating oil systems with ISO VG 46-68 oils for continuous high-speed operation

Inspection intervals

Monitor vibration and temperature every 4-6 hours in heavy-duty cycles
Replace lubricant every 5,000~10,000 hours depending on load severity

Certifications & Compatibility

Standards compliance: Meets ISO 9001:2015 and industry standards (e.g., ISO 281 for load ratings)
Cross-brand compatibility: Interchangeable with equivalent standard models

The 7226AC angular contact ball bearing is engineered for heavy-duty industrial and transportation applications, combining high load capacity (up to 186kN dynamic) with precision and durability. Its non-separable design and standardized interfaces simplify installation, while material and sealing options extend its usability across diverse environments. Paired with proper lubrication and maintenance, this bearing delivers reliable performance in high-speed, high-torque scenarios.

Note: Specific parameters may vary by production standards. Consult technical documentation for detailed specifications.
