Whittet-Higgins

Whittet-Higgins specializes in high-quality bearing retention and shaft-locking products used in demanding industrial applications. Its core product range includes precision locknuts, lockwashers, adapter and withdrawal sleeves, shaft nuts, and related installation tools designed to securely position bearings and rotating components. The company offers both inch and metric options, including heavy-duty and corrosion-resistant designs for power transmission, machinery, and other industrial equipment.

Key Features

  • Internal key engages the shaft keyway; external tangs bend into the locknut slots to prevent loosening
  • Locks and retains bearings and power-transmission assemblies against vibration, shock and torque
  • Carbon steel construction; effective on soft and hardened shafts
  • Meets and exceeds ISO 2982-2:2013(E) (also referenced to ANSI/ABMA 8.1-1986 and DIN 981:1993-02)
  • Max operating temperature approx. 300 deg F (149 deg C)
  • No special tools required for installation; manufactured in the USA, RoHS compliant

Description

The Whittet-Higgins MBB-24 is a heavy-duty metric bearing/shaft lockwasher — a thicker version of the standard MB series engineered for higher-load bearing and power-transmission shaft assemblies. It seats between the bearing and a KM, KML or KMM metric locknut, with an internal key that engages the shaft keyway and external tangs that bend into the locknut slots to lock the assembly against vibration, shock and torque. Manufactured in carbon steel to ISO 2982-2:2013(E).
