🛠️ Features & Benefits

  • Heavy-Duty Mounting: Designed for large shafts (≈110 mm) where tapered-bore bearings must be mounted accurately without shaft shoulders or steps.

  • Standardized Design: Conforms to M125×2 thread and 1:12 taper ratio, ensuring compatibility with matching tapered-bore bearings and locknut systems in the HE series.

  • Secure Locking: Works with KM 22 locknut and MB 22 locking washer to clamp the adapter sleeve and bearing in place for reliable operation under load.

  • Industrial Versatility: Ideal for heavy-load bearings such as 23222 K, 22222 K series and similar sizes, common in industrial gearboxes, heavy machinery, or power transmission systems.
