Backing Bearing

Technical Overview

Backing Bearings (also known as Sendzimir mill bearings) are precision multi-row bearings specifically designed for cluster-type cold rolling mills. These bearings support the intermediate and backup rolls in Sendzimir 20-high mills and similar multi-roll configurations used for rolling thin-gauge stainless steel, silicon steel, and other specialty metal strips. ANDE backing bearings feature precision-ground raceways, optimized roller geometry, and tight dimensional tolerances to ensure uniform strip thickness and surface quality during high-precision cold rolling operations.

Key Features

  • Designed specifically for Sendzimir 20-high cluster mills
  • Multi-row configuration for maximum radial load support
  • Precision-ground raceways for uniform rolling pressure distribution
  • Tight dimensional tolerances ensure consistent strip thickness
  • Premium bearing steel with specialized heat treatment for long service life
