6309-Z-C3 is a deep groove ball bearing, 45 mm bore × 100 mm OD × 25 mm wide (1.7717 × 3.937 × 0.9843 in). It has a metal shield on one side and C3 internal clearance.
The 6309-Z-C3 is a single-shielded deep groove ball bearing with a 45mm bore, 100mm outer diameter, and 25mm width. The single metal shield on one side provides protection from contaminants while allowing easier lubrication access on the open side. C3 radial clearance provides greater internal clearance than standard, accommodating thermal expansion and shaft deflection.
