C.E. Smith 29334
A yellow non-marking bow-bell assembly. The manufacturer specifies an included shaft.
Identify C.E. Smith Boat Trailer Rollers by Shape and Shaft
Replacing a worn trailer roller starts with recognizing its shape: a bell assembly at the bow, a straight keel-support roller, a waisted spool or a compact bow roller. Use the measurements below to identify C.E. Smith parts without assuming that similar black rollers fit the same shaft.
Identify the part by dimensions
Measurements are manufacturer figures in inches. Width and outside diameter are different dimensions, and neither is a substitute for shaft-bore measurement.
| MPN | Roller style | Nominal size/application | Roller/assembly width | Outside diameter | Shaft size |
|---|---|---|---|---|---|
| 29334 | PVC bow-bell assembly | Fits a 3-in centre bracket | 6 in | 4-1/8 in | 1/2 in |
| 29335 | PVC bow-bell assembly | Fits a 4-in centre bracket | 8 in | 5-1/4 in | 1/2 in |
| 29500 | Keel roller | Nominal 12-in roller | 11-3/4 in | 3-1/2 in | 5/8 in |
| 29502 | Keel roller | Nominal 8-in roller | 7-7/8 in | 3-3/8 in | 5/8 in |
| 29522 | Spool roller | Nominal 5-in roller | 4-7/8 in | 3 in | 5/8 in |
| 29541 | Bow roller | Nominal 4-in roller | 3-3/4 in | 3-1/2 in | 1/2 in |
What's included? The bow-bell parts 29334 and 29335 are assemblies with 1/2-inch shafts. For keel, spool and stand-alone bow rollers, check the exact product listing and supplier package to confirm whether a separate shaft is required. Shaft fit is a size specification, not proof that a shaft is in the package.
How to identify a missing or worn roller
If the original package is gone, note the axle-bore diameter and measure the roller's body width, outer diameter and bracket opening. A nominal size can refer to the bracket it fits rather than the assembly's overall width.
- Keel rollers: the 29500 and 29502 use 5/8-inch shafts but have different widths; do not substitute by diameter alone.
- Bow-bell assemblies: the yellow PVC 29334 fits a 3-inch centre bracket, while 29335 fits a 4-inch centre bracket.
- Spool versus bow: part 29522 is a 5-inch nominal spool roller for a 5/8-inch shaft; 29541 is a compact bow roller with a 1/2-inch shaft size.
