Titan part 424-249 is a sleeve bearing designed for use in a wide range of PowrLiner and ProMark II sprayers. This bearing provides a low‑friction, wear‑resistant surface for rotating or oscillating shafts, reducing metal‑to‑metal contact and extending component life. Replacing a worn or damaged sleeve bearing restores smooth operation, eliminates play or binding, and prevents damage to adjacent components.

The Titan 424-249 Sleeve Bearing is a genuine OEM component used in pivot points, shaft supports, and linkage assemblies across a broad range of PowrLiner and ProMark II sprayers. Precision‑machined from durable bearing material, it provides a low‑friction, wear‑resistant surface that supports rotating or oscillating shafts while maintaining precise alignment.
Over time, sleeve bearings can wear, become oval, or crack due to contamination, lack of lubrication, or normal mechanical cycling. A worn bearing leads to excessive play, binding, noise, and accelerated wear of the shaft or housing. Replacing the bearing with the correct 424‑249 part restores proper clearances, smooth motion, and extends the life of the entire assembly.
| Low‑friction support | Provides a smooth, durable surface for rotating or oscillating shafts |
|---|---|
| Prevents metal‑to‑metal contact | Protects shafts and housings from galling and wear |
| Maintains alignment | Holds shafts in precise position, reducing vibration and noise |
| Excessive play | Shaft wobbles or moves laterally within the bearing |
|---|---|
| Binding / rough rotation | Shaft does not turn smoothly, indicating wear or contamination |
| Visible wear or cracks | Bearing surface is scored, flaking, or cracked |
| Noise | Squeaking, grinding, or rattling from the bearing area |

When replacing a sleeve bearing, it is common to inspect or replace associated components that may have been affected by bearing wear.
Inspect the shaft or pin that rides in the bearing for scoring, wear, or out‑of‑round condition.
Check the housing or bracket where the bearing is pressed for damage or deformation.
If the bearing requires grease, ensure grease fittings are clear and functional.
