SANBURG SEALED BALL BEARINGS
n general, ball bearings offer engineers a way to design a continually rotating part, such as a gear, to operate smoothly over time. One particular bearing type, called a sealed ball bearing, has specific differences from the other types of bearings.
Function
Sealed ball bearings perform well within automotive transmissions. Their sealed assembly shields the moving bearings from gear dust and debris, allowing the transmission's mechanical gears to function longer than if the bearing was open to contaminants.
Identification
Sealed ball bearings must have the bearings secured within an outer and inner ring assembly. Additionally, along the assembly rings are synthetic rubber seals, which keep the ball bearings steady within the rings and keep the lubricating grease from leaking outward.
Benefits
The fact that the ball bearings are sealed inside a secured assembly allows the bearing to move freely with little friction. The lack of friction makes the ball bearing well suited for low torque applications within a car's transmission.
