R-Line Hub Assemblies

Raybestos offers three generations of wheel hub assembly units. Each unit is designed to OE specifications and is tested for:

• Endurance
• Temperature control
• Hydraulic and salt resistance
• Metallurgical integrity and vibration

This ensures that our hub assemblies deliver an extended service life and a performance that is:

• Quiet
• Safe
• Consistent

The first step in hub development, Generation 1 consists of a double row contact ball bearing with a split inner ring. The split inner ring allows each ball bearing to rotate independently. Generation 1 does not include a hub, which must be purchased separately.

Features:

• Tapered or ball design
• Double row bearing with angular bearing contact for axial stability
• Pre-lubricated with an integral lifetime seal

Benefits:

• Maintenance free
• Maximized bearing life
• No preloading required
• Compact size

Our next step in hub development, Generation 2 adds a flange that mounts directly to the brake and wheel mount. This eliminates the need for purchasing a separate hub, unlike Generation 1.

Features:

• Flange for wheel and brake rotor attachment
• Tapered or ball design
• Double row bearing with angular bearing contact for axial stability
• Pre-lubricated with an integral lifetime seal
• Integral ABS sensor included with some applications

Benefits:

• Simplified installation
• Requires no adjustment
• Maintenance free
• Maximized bearing life
• No preloading required
• Compact size

Generation 3, our most advanced step in hub development, offers a complete wheel hub assembly. Generation 3 differs from Generation 2 by adding a second flange that fixes the hub assembly to the suspension.

Features:

• Two flanges
  • One for wheel and brake rotor attachment
  • One for fixing the unit to the suspension
• Integral ABS sensor is included with most applications
• Tapered or ball design
• Double row bearing with angular bearing contact for axial stability
• Pre-lubricated with an integral lifetime seal

Benefits:

• Simplified installation
• Requires no adjustment
• Maintenance free
• Maximized bearing life
• No preloading required
• Compact size
