MAHLE Motorsport Main Bearing Set - N14

---

Motorsport-grade main engine bearing set engineered for high-performance applications in MINI Gen 2 engines, including N14 and N18 variants. These precision-manufactured bearings are designed to withstand the elevated loads, sustained high RPM, and extreme thermal conditions associated with track and competition use.

Manufactured from tri-metal or bi-metal materials (depending on application), they feature a steel backing with a copper-lead intermediate layer and an anti-friction overlay for optimal oil film strength, wear resistance, and load distribution. Tight bearing-to-journal tolerances ensure superior crankshaft support, reduced flex, and enhanced engine longevity under stress.

Ideal for use in turbocharged Cooper S and JCW engines (R55–R61 platforms), these bearings are fully compatible with OEM crankshafts and housings, making them suitable for both rebuilds and performance builds. Chamfered edges and precision oil grooves promote efficient lubrication, even under high G-loads and extended high-RPM operation.

Engine Compatibility:

• MINI Gen 2 N14 (Cooper S & JCW)

• MINI Gen 2 N18 (Facelift Cooper S & JCW)

Application:
Track, competition, and high-performance street use.
