ACL Race main bearings for Nissan CA20E / CA18DET / CA16 …

ACL Race Series main bearings are a trimetal design for engines operating at higher RPM conditions. The combination of construction, metallurgy and engineering is intended to support the crankshaft and assist in forming a hydrodynamic oil film.

The set contains ACL Race Series main bearings. Its design includes features for improved bearing retention, heat transfer and consistent clearances.

• High-strength overlay plate with reduced thickness for improved fatigue properties
• Increased crush for improved bearing retention in the housing
• Flash plating eliminated on the back for improved heat transfer and grip between the bearing and its housing
• Increased eccentricity to compensate for bore distortion at high RPM
• 3/4-grooved main bearings to optimize bearing load-carrying surface area and oil flow
• Tight, consistent wall tolerances to help maintain consistent clearances

Suitable for: Ford Corsair I, Nissan 200SX I (S13), Nissan Bluebird I (T72/T12/U12), Nissan Pintara I (U12), Nissan Silvia II (S12).

Engines: CA20E, CA18DET, CA16, CA20S, CA18ET, CA16DE, CA18DE, CA18, CD20T, CD17, CD20 (NISSANCA20E, CA18DET, CA16, CA20S, CA20E, CA18ET, CA16DE, CA18DE, CA18, CD20-T, CD17, CD20).

Sizes

STD is the standard size for an unground crankshaft. Undersizes (−0.25 mm, −0.50 mm …) are for a reground crank, and “+0.025 mm clearance” (X) is for highly stressed engines. Your machine shop chooses the size after measuring.
