Pillow block bearings, also known as mounted bearing units, are robust bearing assemblies consisting of a self-aligning insert bearing mounted in a cast iron, pressed steel, or thermoplastic housing. Designed for easy installation and reliable shaft support, pillow blocks simplify the mounting process by combining the bearing and housing into a single, ready-to-use unit.

These units feature wide inner ring bearings (typically UC-type) with grub screws or eccentric locking collars to secure the shaft, along with spherical outer diameters to compensate for minor shaft misalignment. Pillow block housings often include grease fittings for relubrication, protective end caps, and options for open or sealed bearings depending on the environment.

Pillow block bearings are widely used in conveyors, processing lines, HVAC systems, agricultural machines, and general industrial equipment, offering quick replacement and reliable performance even in dusty, wet, or misaligned conditions.

Key Features:

• Pre-assembled bearing + housing unit for simplified mounting
• Accommodates static shaft misalignment with spherical outer bearing surface
• Set screw or eccentric locking on wide inner ring for secure shaft fit
• Available in cast iron, pressed steel, or thermoplastic housings
• Offered in metric and imperial sizes (e.g., UC205-14, UC207)
• Optional grease fittings, end caps, and dust covers for extended service life

Common Applications:

• Conveyor systems and belt drives
• Food processing and packaging lines
• Agricultural machinery (e.g., harvesters, seeders)
• HVAC blowers and fans
• Textile and woodworking equipment
• Material handling systems
