    Product Description

    The NSK 3307B-2RSRTNGC3 is a double row angular contact ball bearing designed to carry combined radial and axial loads in both directions with high rigidity. The 25° contact angle and C3 internal clearance make it suitable for applications with higher speeds, elevated temperatures, or tight shaft/housing fits.

    The 2RSR rubber seals on both sides protect the internal components from contamination and help retain the factory-applied lubricant, reducing maintenance needs. The TNG polymer cage (glass-fiber reinforced polyamide 66) provides quiet, low-friction operation and good performance at higher speeds.

    Typical applications include:
