Review SUMMIT RACING Engibearing.com Main Bearings 1/2 Groove .010 Inch Under Bimetal Silicon Aluminum Chevy Big Block

The Summit Racing Equipment PART NUMBER: Sum-172210 bearings are specifically designed for use in 1/2 groove applications on Chevrolet Big Block engines. These bearings are manufactured using bimetal technology, which combines the benefits of both steel and bronze materials. The steel outer race provides strength and durability, while the bronze inner race ensures a smooth, low-friction surface for the crankshaft to turn on.

These bearings are ideal for high-performance applications, as they can withstand the increased loads and stresses that come with increased horsepower and RPM. The silicon bronze material used in the inner race also provides excellent resistance to corrosion, ensuring that the bearings will last longer and perform better in harsh environments.

The Summit Racing Sum-172210 bearings are precision machined to ensure a perfect fit and come with a standard 0.010" clearance. The bimetal design allows for a thinner overall size compared to traditional steel bearings, which can help increase clearance and reduce friction. The bearings are also designed to be used with standard press-in installation methods.

It's important to note that these bearings are intended for use in racing or high-performance applications and may not meet the requirements for use in street-driven vehicles. Always consult with a professional mechanic or engine builder to ensure that the correct bearings are being used for your specific application.

In summary, the Summit Racing Sum-172210 bearings are high-performance, bimetal bearings designed for use in 1/2 groove applications on Chevrolet Big Block engines. They offer increased strength, durability, and resistance to corrosion compared to traditional steel bearings, making them an excellent choice for high-horsepower and high-RPM applications.
