Information
Four Point Bearing.
The OE Match Four Point Bearing is a high-quality precision-engineered bearing designed to support both radial and axial loads within critical Porsche mechanical assemblies. Manufactured to OE specifications for fit, performance and durability, this four-point contact bearing is designed to provide smooth rotational movement while maintaining accurate component alignment under varying operating conditions.
Fits:
Diagram Ref No 18
Featuring a specialised internal design that allows load distribution across four contact points, this bearing can accommodate forces acting in multiple directions while reducing friction and wear. Constructed from high-grade bearing steel and engineered for long service life, it plays a vital role in maintaining the reliability and efficiency of the components in which it is installed.

Constructed from high-grade bearing steel and engineered for long service life, it plays a vital role in maintaining the reliability and efficiency of the components in which it is installed.
What This Product Does:
- Supports rotating components under radial and axial loads.
- Maintains precise alignment within mechanical assemblies.
- Reduces friction between moving parts.
- Distributes loads evenly across multiple contact points.
- Allows smooth and efficient rotational movement.
- Minimises wear on associated components.
- Contributes to reliable operation and long-term durability.
Symptoms Of Wear Or Failure:
- Grinding, rumbling or humming noises during operation.
- Excessive vibration from the affected assembly.
- Increased mechanical resistance or rough movement.
- Component misalignment or excessive play.
- Premature wear of surrounding components.
- Overheating caused by increased friction.
- Reduced performance of the supported assembly.
- Metal particles or bearing debris found during inspection.
- Complete bearing seizure in severe failure cases.
Why Replacement Matters:
- Bearings are subjected to constant rotational forces, load changes, vibration and environmental contamination throughout their service life. Over time, wear of the bearing races, rolling elements or cage assembly can reduce bearing performance and compromise component alignment.
- A failing bearing can increase friction, generate excessive heat and place additional stress on surrounding mechanical components. If left unresolved, bearing failure can result in significant damage to shafts, housings and related assemblies, leading to costly repairs and unexpected downtime.
- Replacing a worn four point bearing restores smooth operation, maintains correct load support and helps protect associated components from premature wear. An OE Match replacement provides factory-style fitment, precision manufacturing and dependable long-term durability, ensuring reliable performance and maintaining the engineering standards expected of your Porsche.
