210866-1X – Center Support Bearing – 1350/1410 Series – 1.574″ ID – 2.250″ Center Bearing To Base

Both the 1350 and 1410 U-joint series use a 1.188-inch cap diameter, which means stub shaft diameters within these two series are dimensionally compatible at the center support bearing. The 210866-1X carries a 1.574-inch inner bore and 2.250-inch center-to-base height that serves both series -- the series designation on a CSB describes the rated torque capacity of the surrounding hardware, not a dimensional incompatibility at the bore.

• SKU: 210866-1X
• Compatible Series: 1350, 1410
• Inner Bore Diameter: 1.574 inches
• Center-to-Base Height: 2.250 inches
• Part Type: Center Support Bearing with rubber isolator

The 2.250-inch height positions the midshaft at the designed driveshaft angle for applications using this unit. If your repair involves a vehicle that originally had a bearing with a different center-to-base measurement, substituting the 210866-1X will shift the driveshaft angularity and alter U-joint operating angles on both ends of the midshaft -- enough to cause vibration or premature joint wear even after a new install.

Confirm your stub shaft OD with calipers before pressing. The 1.574-inch bore is nominal; actual clearance tolerances are tight, and a stub shaft that runs oversize from corrosion or prior damage will gall the new bearing bore during installation.
