Product Overview
The 570037/A Needle Bearing is a factory-original (OEM) part designed for the “Timing Side” or Right Hand (RH) Crankshaft support in Royal Enfield 350cc and 500cc UCE models. Featuring a compact 30x45x20mm profile, this needle roller bearing is capable of handling immense radial loads while maintaining a slim sectional height—perfect for the tight tolerances of the RE engine casing.
If you are experiencing unusual “knocking” from the engine side, increased vibration, or are performing a full engine rebuild, replacing this bearing is essential to prevent crankshaft misalignment and premature engine failure.
