Titan part 779-068 is a replacement bearing designed for rotating assemblies such as wheels, caster pivots, or drive components on compatible Titan PowrLiner 2800, 4900, 4900 XLT, 4950, 6900 XLT SP, 6900 XLT, 6950, 8900 XLT SP, 8900 XLT, 8900, 4955, 6955, and 8955 stripers. This bearing provides smooth, low‑friction rotation and supports radial and axial loads encountered during operation. Replacing a worn, rough, or noisy bearing restores smooth rolling, reduces steering effort, and prevents damage to surrounding components.

The Titan 779-068 Bearing is an OEM precision bearing used in wheel hubs, caster yokes, pivot points, or drive line components on a wide range of PowrLiner stripers. It is designed to handle the heavy loads and continuous operation typical of pavement marking equipment.
Bearings gradually wear due to dust, moisture, and load cycles. Symptoms include roughness when turning, grinding noises, wheel wobble, or increased pushing effort. Replacing with genuine Titan 779-068 restores smooth rotation, extends the life of associated parts, and keeps the striper rolling true.
| Low‑friction rotation | Allows wheels and pivots to turn freely |
|---|---|
| Load support | Carries machine weight and side loads |
| Alignment | Maintains precise positioning of rotating parts |
| Rough / gritty feel | Bearing does not spin smoothly |
|---|---|
| Excessive play | Wobbling wheel or loose caster |
| Noise | Grinding, clicking, or squealing during rotation |
| Visible damage | Cracked race, missing balls, rust |

When replacing a bearing, consider inspecting or replacing these associated components.
Replace seals at the same time to keep contaminants out of the new bearing.
Check for scoring or wear; a damaged bore will cause premature bearing failure.
Inspect for pitting or scoring; replace if the bearing does not slide on smoothly.
