Wolfram Shaft Sleeves

Name: Wolfram Shaft Sleeves
SKU: 99
Availability: InStock

Price range: $834.23 through $6,073.20 ex. GST

Our Wolfram Shaft Sleeves are engineered for Australia’s harshest mine-site slurry systems. Built with a proprietary solid Wolfram material and polished to a mirror finish, they deliver significantly greater durability than conventional sleeve alloys.

Compatible with multiple pump brands and designed for retrofit ease, they help reduce downtime and maintenance cost.

Improved bearing reliability and extended wear life.

In heavy duty slurry applications where corrosion, erosion and high wear rates dominate, standard shaft sleeves often become a maintenance-bottleneck. The Wolfram Shaft Sleeves from 7D Team employ a solid Wolfram construction at ~1300 Vickers hardness, mirror surface finish (< Ra 0.2), and corrosion-resistant performance to withstand extreme duty.

Includes:

Hardness of approx. 1300 Vickers — far higher than conventional materials.
Mirror finish surface finish (< Ra 0.2) to minimise wear and fluid ingress.
Broad temperature rating (-30 °C to +1000 °C) and corrosion resilience for the harshest conditions.
Custom-design capability to suit many pump frames/brands (retrofit ready).

Features and benefits

Installing Wolfram Shaft Sleeves can transform your maintenance cycle, reduce spares burden and boost uptime, all while supporting your safety and cost-control goals.

Dramatically longer wear life — up to 3× guarantee, with many field reports exceeding 10× life of standard materials.
Reduced maintenance interventions — fewer rebuilds, less sleeving downtime.
Improved reliability in corrosive, highly abrasive environments where conventional sleeves fail quickly.
Retrofit-friendly — drop-in replacement for many existing pump brands, avoiding full equipment change-out.
Optimised spares management — one high-performance sleeve covers multiple applications and brands.
Enhanced safety & environmental compliance — less leakage, fewer failures, lower risk of shutdown impacts.
