The 700-689 Bronze Bearing is a precision sleeve bearing manufactured from high‑quality bronze alloy, designed for use in Advantage GPX 85, PowrLiner 2850/1800M/2800M, SprayTech GPX 85, ProMark II, and RentSpray 700 equipment. It provides a durable, low‑friction surface for rotating or oscillating shafts in pumps, drives, and other mechanical assemblies.
Bronze bearings are valued for their excellent wear resistance, conformability, and ability to operate with minimal lubrication. They are commonly used in applications where maintenance access is limited or where lubrication may be intermittent. Over time, bearings can wear due to normal use, contamination, or inadequate lubrication, resulting in increased clearance, vibration, and potential shaft damage. Replacing a worn bearing restores proper shaft support and extends equipment life.
| Shaft support | Provides a smooth bearing surface for rotating shafts |
|---|---|
| Friction reduction | Minimizes wear on both shaft and housing |
| Alignment | Maintains proper shaft positioning within the assembly |
| Excessive play | Noticeable shaft movement within the bearing |
|---|---|
| Visible wear | Scoring, galling, or deformation of bearing surface |
| Noise / vibration | Unusual sounds or vibration during operation |
| Disassembly | Always replace bearing when servicing related components |

When replacing the bronze bearing, these components are often inspected or replaced at the same time to ensure complete system reliability.
Inspect for scoring or wear; a damaged shaft will quickly wear a new bearing.
Replace any seals that may have been compromised during disassembly.
Fresh lubricant ensures proper break‑in and long bearing life.
