Product Details

SMMT CB2-200 Heavy-Duty 2-Inch Pillow Block Bearing Unit | Extreme Load & Vibration

The SMMT CB2-200 2" Pillow Block Bearing is engineered for relentless performance in the most demanding industrial environments, including aggregate processing, bulk material handling, and mining applications. This unit features a robust, split-cast iron housing (CB2 series) designed to absorb significant shock loads and minimize vibrational noise, ensuring prolonged component life. The included self-aligning insert (typically UC210 series equivalent) boasts high-precision raceways and is securely locked with dual set screws, providing superior shaft grip and excellent protection against axial movement. Factory-filled with high-temperature grease and equipped with a standard Zerk fitting, the CB2-200 ensures ease of maintenance and maximal uptime. Optimized for reliability and reduced total cost of ownership (TCO), the CB2-200 incorporates a triple-lip contact seal system that effectively excludes contaminants (dust, moisture, wash-down chemicals) while retaining vital lubrication. Its design prioritizes operational stability, offering superior dynamic and static load ratings essential for heavily loaded conveyor systems and processing machinery. This unit offers a drop-in replacement solution designed to meet or exceed OEM specifications, allowing maintenance teams to quickly restore machinery function with a unit built for long-term endurance and minimal bearing replacement frequency.

Key Features

  • Robust Cast Iron Housing optimized for shock load absorption and vibration dampening.
  • Triple-Lip Contact Seals provide superior protection against ingress of dust and moisture.
  • High Static and Dynamic Load Ratings suitable for extreme duty cycles.
  • Corrosion-Resistant Finish ensures longevity in harsh, exposed industrial environments.
  • Drop-in interchangeability with major bearing manufacturers' standard pillow block units.
