How to install and maintain RUS26086

1. Installation

Pre‑installation preparation

• Clean mounting base and guide rail contact surfaces completely: remove chips, burrs, dust, residual oil. Mounting surface flatness must meet machine‑tool grade requirements.
• Do NOT remove the temporary holding mandrel before fitting onto rail. Never pull the carriage off the rail freely; rollers will fall out and damage the unitINA.
• Check hardware: use 12.9‑grade hex socket cap screws. Tightening torque for top M6 screws.
• Prepare torque wrench, dial indicator, suitable grease, external seals/scraper accessories (this model has no built‑in seals).

Mounting steps

• Slide RUS26086 carefully onto the matched guide rail; remove temporary mandrel only after fully engaged on rail.
• Position carriage against reference locating shoulder on the sliding table. Insert mounting screws, tighten hand‑tight first.
• Tighten screws in diagonal sequence, two‑stage tightening (50% → 100% rated torque 17 Nm for M6) to avoid tilting and preload distortion.
• For RUS26086‑KS version: adjust preload via the adjustment clip. Manually move carriage back‑and‑forth: smooth travel, no sticking, no excessive play, no heavy drag. Do not over‑preload (will cause overheating & rapid wear).
• Mount external scrapers / end seals for dusty, chip‑generating environments; ensure no contact friction between seal lips and rail surface.
• Mount grease nipple (M6 thread) on lubrication port.
• Manual full‑stroke test run: travel full length several times. Confirm silent, uniform movement, no jerking or abnormal noise.

Critical warnings

• Never hammer or strike the carriage directly; impact damages rollers and raceway precision.
• Multi‑carriage / multi‑rail system: control parallelism and flatness, avoid skew load.
• Vertical / overhead installation: fit anti‑drop safety structure to prevent carriage falling.

2. Lubrication

Initial filling: add lithium‑based EP grease before commissioning. Pump grease until fresh grease slightly oozes from side gaps.

Relubrication port: M6 thread on end face / side face.

3. Regular Maintenance

Routine inspection (daily / weekly)

• Check for abnormal noise, vibration, jerky movement. Stop machine immediately if anomalies occur.
• Check seal / scraper condition: clear chips and dirt from scraper.
• Check mounting screws for loosening; re‑check torque periodically.
• Observe temperature rise: excessive heating indicates over‑preload, poor lubrication or misalignment.

Periodic maintenance

• Relubricate following interval table; purge old contaminated grease.
• If heavily contaminated: disassemble external seals, clean rail surface, re‑grease, reassemble seals. Do not wash open carriage with solvent (rollers/cage may be damaged).
• Monitor positioning accuracy. Gradual accuracy drop indicates roller / raceway wear.

Failure hints

• Sticking / heavy drag: over‑preload, misalignment, dirt ingress.
• Rattling noise: lost preload, loose mounting, roller wear.
• High temperature: too much preload, insufficient lubrication.

4. Storage & Handling

Store horizontally in dry, clean place, anti‑rust protected. Do not take carriage off rail during storage.

Avoid shock, drop. Protect raceway surfaces from scratches.
