Ball Bearing, 6309 C3, Leybold, Sogevac, Part# 971425960

This is a high-quality 6309 C3 deep groove ball bearing. The “C3” means it has more internal clearance than a standard bearing. That extra space is important. Your pump gets hot during normal operation. The C3 clearance lets the bearing expand safely without getting stuck. So your pump keeps running smoothly, even under heavy use.Strong and dependable.
The bearing is made from durable chrome steel. It is a single-row bearing, which is the best design for handling radial loads. Radial loads are the weight that presses down on the shaft as it spins. This bearing carries that weight easily. It also has a steel sheet metal cage that holds the balls in place evenly.
