HE 3128 Adapter Sleeve | 140mm Shaft Tapered Withdrawal Sleeve | Metric Industrial Bearing Mount
The HE 3128 Adapter Sleeve is an essential precision component designed for mounting spherical roller bearings or self-aligning ball bearings with a tapered bore onto a cylindrical shaft. Utilizing the standard 1:12 taper, this sleeve ensures a precise interference fit, maximizing load distribution and stability in high-stress applications. Fabricated from high-strength carbon steel, the HE 3128 is dimensionally controlled to strict ISO standards, providing reliable performance and interchangeability across global industrial equipment. Proper installation with the specified locking nut (KM 28) ensures exceptional axial positioning and prevents loosening under heavy vibrational loads.
Optimizing mounting procedures is crucial for minimizing equipment downtime. The HE 3128 facilitates straightforward installation and, critically, easy removal using withdrawal tools or hydraulic methods, reducing labor time during maintenance cycles. Recommended for heavy-duty environments such as mining conveyors, pulp and paper machinery, and large industrial gearboxes, this adapter sleeve provides a secure and durable mounting solution that significantly extends the service life of the associated bearing unit. Choosing the correct HE sleeve ensures system reliability and operational efficiency in demanding industrial settings.
