Center Support Bearing

A center support bearing — also called a carrier bearing, midship bearing, or hanger bearing — is the rubber-isolated ball bearing assembly that supports the center of a two-piece driveshaft. On trucks, SUVs, and commercial vehicles with long wheelbase drivelines, splitting the shaft into two sections with a carrier bearing in the middle allows the critical speed (the RPM at which a spinning shaft begins to resonate) to be kept above the operating range. Without this support, a long single-piece shaft would whip and vibrate at highway speeds.

When a center support bearing fails, symptoms include:

Vibration or shudder at specific road speeds (typically 45-70 mph)
Grinding or rumbling noise that increases with vehicle speed
Visible rubber cracking or collapse in the bearing bracket assembly
Grease leaking from the bearing housing

When ordering a center support bearing, you need: bore ID (the shaft diameter it rides on), overall bracket width, and the outer race diameter or bracket bolt pattern. Our product listings include all critical dimensions — confirm these against your existing bearing before ordering.
