Titan part 757-089 is a gun bar slide (also known as a gun carriage slide or spray gun rail) used on compatible PowrLiner airless stripers. This component allows the spray gun assembly to move smoothly along the guide bar for precise line marking and consistent stripe placement. A worn, bent, or binding slide can cause uneven paint lines, difficult gun positioning, or erratic movement during operation. Replacing the slide restores smooth, accurate gun travel.

The Titan 757-089 Gun Bar Slide is a replacement carriage component that allows the spray gun to traverse the gun bar (guide rail) on compatible PowrLiner airless striping machines. It is typically made of low‑friction material or precision‑machined metal to ensure smooth, backlash‑free movement for consistent stripe alignment.
Over time, slides can wear from debris, lack of lubrication, or impact damage. A worn slide causes binding, uneven paint line edges, difficulty positioning the gun, or sloppy lateral movement that affects stripe straightness. Replacing the slide restores factory‑smooth travel and precise gun control.
| Smooth lateral travel | Allows spray gun to slide left/right along the gun bar |
|---|---|
| Precise stripe placement | Maintains consistent gun position for straight lines |
| Reduced play | Minimizes side‑to‑side wobble during marking |
| Quick adjustments | Enables fast repositioning between stripe widths |
| Binding / sticking | Slide does not move freely along the bar |
|---|---|
| Excessive play | Gun wobbles side‑to‑side when locked or moving |
| Visible wear or cracks | Worn plastic bushings, cracked metal ears, or deformed shape |
| Uneven paint lines | Stripe edges are jagged or inconsistent |

When replacing the gun bar slide, inspect these associated components for optimal performance.
Inspect for nicks, rust, or bends that could damage the new slide.
Worn locking mechanisms can allow unwanted slide movement.
Check for cracks or loose bolts that affect gun alignment.
