Engine Ball Bearings:TRA 2.5(2). QTY 1 14x25.4x6mm Rear Engine Bearing. QTY 1 7x19x6mm Front Engine Bearing. Applications: Most Nova Rossi .21cc Engines. For the Nova Rossi 21 P5X Engine, search our online store for P5X. most of the times the inner side is more worn then the outside. Change the bearing if needed. Apply clean engine oil to the new components, and lock the bearing with the clip. Material: Aluminum based alloy or copper based alloy and Babbitt. Good resistance to corrosion. High thermal conductivity
High fatigue strength. Plating, size and other performance reach OE standard. Outside diameter from 21MM to 305MM. STD, 010, 020, 030, 040, 050 (STD, 0. 25, 0. 50, 0. 75, 1. 00, 1. 25). DIN/ISO4383 and SO/TS16949 certificated. the materials are developed as an improvement on the white metal and copper based alloys to provide bearings that carry high loads.

Nissan 240SX. SR20 2.0L Tri-Metal Main Bearing - Race. Built for the Nissan 240SX... Engine bearings are one of the most vital components within an engine and are often overlooked when considering high performance upgrades. Performance engineered, multi-layer bearings generate less heat than normal bearings by reducing friction. Cosworth Race bearing sets feature a unique combination of design, metallurgy and engineering to deliver what drivers expect from high performance engine bearings.Engineered with the following features: - High strength overlay plate with reduced thickness for better oil control and less friction - Hardened steel backing on all connecting rod bearings - Increased crush and elimination of flash plating - 3/4 grooving on Main Bearings providing optimum oil supply - Tight consistent wall tolerances.
