What the center support bearing does
On a vehicle with a two-piece propshaft, the center support bearing — also called the bracket bearing, and in the trade the carrier bearing — carries the middle of the shaft. The catalogue describes its job as support, stability and shock absorption: the bearing sits in a rubber-mounted bracket bolted to the body or a crossmember, and it is the part that keeps a long shaft running true.
The published catalogue carries 249 listings in this family, ranged under HB-series numbers, with examples such as HB88107 and HB88512 appearing across the company's own listings together with their vehicle fitments.
How the HB series is organised
HB numbers group the family by the bracket and bearing combination rather than by vehicle, which is why one HB number serves several applications. The company's listings pair the HB number with fitments — the same unit appearing against Chevrolet, Dodge, Ford, GMC and Isuzu applications, or against Volvo and DAF in the case of numbers such as 1435557 — because the shaft, not the badge, decides the part.

Ordering the right support bearing
Quote the HB number or the cross-reference from the old unit, and the bracket shape is already settled. Quote only the vehicle and the match needs the shaft arrangement as well — two-piece shafts differ by wheelbase on the same model. The driveshaft guide works through the identification in the order a workshop meets it.
Paired replacement with universal joints
A worn center support bearing and worn universal joints present together — vibration under load, a shudder on take-off — and the two families are often ordered on the same list. The universal joint family is ranged alongside, and the driveline blog article covers ordering the pair.
