3180-10 – Center Support Bearing – 1210/1310 Series – 1.181″ ID – 1.950″ Center Bearing To Base

Q: Does the 3180-10 fit both 1210 and 1310 series driveshafts? A: Yes. Both 1210 and 1330 (and 1310) series can use the same center bearing bore because the stub shaft journal diameter is determined by the stub shaft OD, not the U-joint series. The 1210 and 1310 series both use 1.062" U-joint cap diameter, but the stub shaft journal for a 30 mm bore application (1.181") is specific to the vehicle design.

Q: What is unusual about the 1.950" center-to-base height on the 3180-10? A: The 1.950" dimension falls between the standard 1.875" and 2.000" values. Like other non-standard heights, it is application-specific and cannot be substituted with a unit that rounds to the nearest half-inch. Measure the removed bearing with a digital caliper before ordering.

Q: What center support bearing cross-references apply to the 3180-10? A: Spicer and Neapco cross-references may exist in the 2-26 and 2-3049 families depending on the specific application. The 1.181" bore and 1.950" height combination is not covered by the most common domestic truck cross-references, which use larger bores; contact the supplier with your vehicle information for a confirmed cross-reference.
