FAFNIR MUA 1 15/16 Pillow Block Mounted Ball Bearing Unit | Heavy Duty Cast Iron

The FAFNIR MUA 1 15/16 unit represents a gold standard in industrial mounted bearing assemblies, designed for demanding applications requiring robust performance and exceptional reliability. This heavy-duty pillow block housing, constructed from high-grade cast iron, provides superior rigidity and vibration damping. The internal bearing insert features an enhanced eccentric locking collar, ensuring positive shaft retention and minimizing slip, even under variable load and rotational speed conditions. Equipped with Fafnir's proprietary R-Seal or comparable triple-lip sealing system, the MUA 1 15/16 effectively excludes fine particulate matter and moisture while retaining lubrication, drastically extending the service interval and maximizing uptime in contaminated environments such as mining, forestry, and aggregate handling. Engineered for easy installation and maintenance, this unit incorporates a self-aligning capability to compensate for initial shaft misalignment, preventing premature bearing failure caused by undue stress. Its re-lubrication feature, accessible via a standard grease fitting, allows for field maintenance, ensuring optimal bearing life in high-temperature or high-contaminant operations. Specifying the FAFNIR MUA 1 15/16 minimizes Total Cost of Ownership (TCO) by reducing unscheduled downtime and labor costs associated with frequent replacements. It is the definitive choice for critical power transmission points on conveyors, fans, and processing machinery.

Key Features

  • Robust Cast Iron Housing for maximum structural rigidity and shock resistance.
  • Precision-engineered eccentric locking collar ensures secure, positive shaft attachment.
  • Triple-lip R-Seals provide superior exclusion of contaminants (dust, water spray).
  • Self-aligning capability accommodates static misalignment up to 2 degrees.
  • Designed for relubrication, extending life in harsh temperature and load conditions.
  • Ideal for severe-duty applications including mining, aggregate, and pulp/paper industries.
