1480-10 – Center Support Bearing – Volvo Application – 1.378″ ID – 2.750″ Center Bearing To Base

Q: What distinguishes the 1480-10 from the 1480-40 for Volvo applications? A: The 1480-40 uses a 2.310" center-to-base height; the 1480-10 uses 2.750". Both have a 1.378" bore and are 1480-series assemblies. The height difference reflects different Volvo model configurations or crossmember positions. Measure the removed bearing to determine which unit applies.

Q: Is the 1480-series center support bearing compatible with 1350-series driveshaft stubs? A: The center support bearing bore dimension (35 mm / 1.378") is independent of the U-joint series designation. The series number indicates which U-joint cap size the driveshaft uses, not the stub shaft diameter. A 1480-series driveshaft can share the same stub shaft journal size as a 1350-series shaft -- verify the actual stub shaft OD rather than relying on the series number alone.

Q: How often should Volvo center bearings be replaced in commercial service? A: Volvo commercial applications typically schedule center bearing inspection at 100,000 km intervals, with replacement at first sign of roughness, noise, or visible rubber cracking in the isolator. Severe-duty applications (mining, forestry, heavy towing) require shorter inspection intervals of 50,000 km.
