The Wacker Neuson Antifriction Runner is a genuine OEM component designed for LTS4K, LTS7K, LTS8K, and LTS8L series light towers. As a direct Wacker Neuson OEM part, the is manufactured to the exact material and dimensional tolerances of the original, ensuring proper fit and consistent performance across the full range of compatible units. Fitment covers both 50 Hz and 60 Hz configurations as well as trailer and skid-mounted variants within the LTS and LTE series lineup.

Key Features

  • Low-Friction Surface Integrity — Manufactured to OEM tolerances, this antifriction runner maintains the low-resistance sliding contact the mast or moving assembly depends on for smooth, controlled operation.
  • Drop-In OEM Replacement — Matches the original mounting profile and contact geometry exactly, allowing straightforward removal and reinstallation without rework or shimming.
  • Broad LTS and LTE Series Compatibility — Confirmed fitment across LTS4K, LTS7K, LTS8K, and LTS8L light tower models, covering both trailer and skid configurations and multiple frequency variants.
  • Protects Adjacent Components — A worn or degraded antifriction runner increases metal-on-metal contact stress, accelerating wear on the mast and surrounding hardware; replacing it promptly preserves the integrity of the full assembly.
  • Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, so the material grade and geometry match the original specification without substitution or compromise.

An antifriction runner is a wear-contact component positioned between two moving or load-bearing surfaces — in this case within the light tower mast assembly — to reduce friction and prevent direct metal-to-metal wear during raising, lowering, or positional adjustment. It acts as a sacrificial bearing surface, absorbing the contact stress so that the structural components around it are protected. When an antifriction runner wears down or becomes damaged, movement becomes stiff or uneven, and the surrounding mast components begin to experience accelerated wear that can lead to more costly repairs.
