Cam Bearing Set - 50mm Roller Bearing

The DART Cam Bearing Set – 50mm Roller Bearing (SKU DRT32220041-5) is a precision camshaft bearing assembly engineered for high-performance big-block Chevy engine builds. This five-piece roller bearing set delivers the durability and load capacity required in high-RPM applications where standard bearing materials fall short. The 50mm journal diameter accommodates DART's proven big-block Chevy platform, making this bearing set a critical component for engine builders and performance machine shops targeting consistent valve timing and reduced friction across the entire powerband.

Roller bearings in camshaft applications provide superior load distribution compared to plain journal bearings, reducing wear on both the camshaft lobes and bearing surfaces during sustained high-RPM operation. The 50mm specification ensures compatibility with DART big-block Chevy engine blocks and cam profiles, while the five-bearing configuration maintains proper camshaft alignment across the full length of the block. Precision manufacturing tolerances guarantee consistent fit and minimal radial play, which is essential for maintaining accurate cam timing and preventing bearing noise or premature failure in high-output engines.

This bearing set is specified for engine builders assembling DART big-block Chevy blocks for street performance, drag racing, marine, and off-road applications where camshaft reliability is non-negotiable. Whether you're rebuilding a stock displacement engine or installing an aggressive aftermarket camshaft profile, this five-piece set ensures your cam runs true and free of bearing-induced resistance. Proper bearing selection directly impacts horsepower delivery and engine longevity—this set removes guesswork from that critical decision.
