Wear Sleeve

Wear Sleeve – High-Performance Shaft Protection Sleeve for Pumps, Agitators, and Rotating Equipment in Abrasive, Corrosive, and High-Wear Industrial Applications Across the GCC

In rotating machinery exposed to abrasive slurries, corrosive chemicals, or high-speed wear, the Wear Sleeve is a cost-effective, sacrificial barrier that protects the original shaft from irreversible damage. Designed to be installed directly onto pump, mixer, or compressor shafts, this precision-engineered sleeve takes the brunt of erosion, corrosion, and mechanical wear—allowing for quick, economical replacement without the need to re-machine or replace the entire shaft. From wastewater treatment plants in Dubai and phosphate slurry pumps in Saudi Arabia to chemical agitators in Qatar and desalination feed systems in Oman, Qalalam Industrial Supply delivers high-integrity Wear Sleeves in stainless steel 316, hardened carbon steel, or tungsten carbide, featuring precision-ground bores (h7 tolerance), mirror-finish sealing surfaces (Ra ≤ 0.4 µm), and corrosion-resistant materials—ensuring extended equipment life, reduced downtime, and lower maintenance costs across the harsh industrial environments of the Middle East.

Unlike temporary fixes or generic tubing, a true Wear Sleeve is engineered as a functional extension of the shaft, providing not only wear protection but also a reliable sealing surface for mechanical seals or packing. Whether used as an OEM replacement or retrofit solution, our sleeves deliver the dimensional accuracy, surface quality, and material resilience that keep critical rotating equipment running reliably in the most demanding GCC applications.

Dual Purpose: Wear Protection + Sealing Surface

The Wear Sleeve solves two critical maintenance challenges:

1. Shaft Preservation:
   Acts as a sacrificial layer that absorbs abrasion from sand, grit, crystals, or fibers—saving the base shaft from scoring, pitting, or erosion.
2. Seal Compatibility:
   Provides a smooth, hardened surface for mechanical seals or packing to run against—preventing leakage, hang-up, or premature seal failure.

Replacing a $150 wear sleeve is far more economical than replacing a $2,000 pump shaft or suffering days of unplanned downtime.

All sleeves are stress-relieved after machining to prevent distortion during operation or installation.

Precision Manufacturing: Tolerances That Ensure Seal Life

Our production process ensures reliable performance with seals and packing:

• Bore Tolerance: h7 (±0.018mm for 50mm shaft) — for interference fit
• OD Tolerance: h6 (±0.016mm) — for seal compatibility
• Surface Finish:
  • Sealing surface: Ra ≤ 0.4 µm (standard), Ra ≤ 0.2 µm (for high-speed seals)
  • Non-sealing areas: Ra ≤ 0.8 µm
• Straightness: ≤ 0.02mm per 100mm length
• Edge Break: 0.2mm chamfer (prevents seal damage during installation)

🔧 Why it matters: A 0.05mm surface scratch on the sealing surface can cause mechanical seal face distortion—leading to leakage within hours.

Frequently Asked Questions (FAQs)

Q1: What’s the difference between a wear sleeve and a shaft sleeve?
A: The terms are often used interchangeably. However, a wear sleeve emphasizes sacrificial protection in abrasive/corrosive service, while a shaft sleeve may refer to a permanent sealing surface. In practice, our sleeves serve both functions—protection + sealing.

Q2: Can I install a wear sleeve in the field without a machine shop?
A: Yes—with proper tools:

• Thermal fit: Heat sleeve to 150°C, cool shaft to –20°C (dry ice)
• Hydraulic press: For interference fits
• Never hammer directly—use a shoulder driver
  We provide a free installation guide with every order.

Q3: How do I know when to replace the wear sleeve?
A: Replace when:

• Visible wear flat > 0.5mm on the sealing surface
• Surface roughness > Ra 0.8 µm (use profilometer)
• Leakage occurs with new seals
• Pitting or corrosion is visible
  Proactive replacement every 6–12 months in harsh service is recommended.

Q4: Are your sleeves compatible with all mechanical seal brands?
A: Yes. Our sealing surfaces meet international standards for:

• John Crane, EagleBurgmann, Flowserve, Burgmann, AESSEAL
  If you provide your seal model, we’ll verify compatibility.

Q5: Can you make sleeves with keyways or splines?
A: Yes. We machine:

• Parallel keys (ISO 773)
• Splines (ANSI B92.1)
• Custom drive features
  Just provide your shaft drawing.

Q6: What’s your lead time for tungsten carbide sleeves?
A: 7–10 days from Dubai. We keep SS 316 and hardened steel in stock for next-day delivery.

Q7: Do you offer sleeve refurbishment or regrinding?
A: Regrinding: yes—if wall thickness allows (min. 1mm remaining). We restore diameter and surface finish to as-new condition. Cost: 40–60% of new.
