Rear wheel bearing seal outer. DG 62 x 68 x 6 / 10.
OE Match rear wheel bearing outer seal engineered to replicate the original factory sealing component used on early Porsche 911 and 912 models (1965–1968). It is designed to fit into the wheel hub to seal the outer side of the rear wheel bearing, keeping lubricant in and contaminants out.
Sold per each, 2 required per car.

Fits:
Porsche 911 2.0 01/1963 - 07/1968
Porsche 912 1.6 01/1965 - 07/1968

Diagram Ref No 10

The rear wheel bearing outer seal prevents lubricant loss from the wheel hub and keeps dirt, water, and debris out of the bearing assembly. By maintaining correct lubrication and preventing contamination, the seal helps ensure smooth bearing rotation and prolongs the service life of the wheel bearings.

Function:
Installed on the outer side of the rear wheel hub, this seal:
Retains bearing lubricant inside the hub assembly
 Keeps water, mud, dust, and road contaminants out
 Protects internal bearing surfaces from corrosion and wear
•  Maintains correct contact with the rotating bearing outer race
Accurate lip geometry and correct seal dimensions are essential to form a tight sealing interface while accommodating hub rotation and slight shaft movement.

Wheel bearing seals protect the integrity of the bearing assembly - a critical rotational component subjected to high loads, speed, and road conditions. A worn, cracked, or leaking seal can allow grease to escape and contaminants to enter, resulting in accelerated bearing wear, noise, vibration, and ultimately bearing failure. Installing fresh OE Match seals helps preserve bearing lubrication and contributes to smooth, quiet rear wheel rotation and long service life.

When to replace:
  During wheel bearing service or rebuild
  If seal lip is cracked, hardened, or visibly worn
  When grease appears contaminated, leaking, or lost
  After water exposure or road debris impact
  As preventive maintenance on unrestored classic vehicles

About Wheel Bearings & Kits

Porsche Wheel Bearings & Kits | Design911 Suspension Components for Smooth Rotation, Precision & Safety

Wheel bearings are critical components within your Porsche’s suspension and axle assembly, ensuring smooth, friction-free rotation of the wheels. They support the vehicle’s weight while allowing the wheels to spin precisely and quietly at high speeds. Properly functioning bearings contribute to stability, ride comfort, and predictable handling — all essential for maintaining the performance and safety your Porsche is known for.

At Design911, we supply a complete selection of wheel bearings and bearing kits, engineered for precision fitment, strength, and longevity. Each bearing set is crafted from premium-grade materials and designed to meet the high-performance demands of both classic and modern Porsche models. Whether for routine maintenance, performance upgrades, or full restoration, our range ensures your Porsche delivers a quiet, stable, and confident ride.

What Do Wheel Bearings Do?

Wheel bearings enable the wheels to rotate smoothly around the hub while supporting vertical and lateral loads.

Core Functions:
• Allow free and precise wheel rotation with minimal friction.
• Support vehicle weight while maintaining wheel alignment.
• Reduce vibration, noise, and rolling resistance.
• Enhance cornering stability and braking performance.
• Protect suspension and hub components from excessive wear.

High-quality bearings ensure quiet operation and smooth performance, providing the secure, agile driving dynamics that Porsche drivers demand.

Why Do Wheel Bearings Fail or Degrade?

Wheel bearings operate under high load, temperature, and rotational stress — eventually leading to wear or damage.

Common Causes of Failure Include:
• Contamination from water, dirt, or road debris.
• Loss of lubrication or grease degradation.
• Corrosion or pitting of the bearing races.
• Impact damage from potholes or kerbs.
• Wear due to age or improper installation torque.

When wheel bearings fail, symptoms can include humming noises, vibration, wheel play, or uneven tyre wear — all of which reduce handling precision and driving safety.

Why Replace or Upgrade Your Porsche Wheel Bearings?

Replacing worn wheel bearings restores smooth, quiet operation and ensures stable, predictable handling. Upgraded bearing kits offer increased durability for high-performance or track-driven vehicles.

Key Benefits:
• Eliminates vibration, wheel play, and noise.
• Restores precise steering and suspension stability.
