This is a replacement pillow block bearing for 48" PolarCool belt drive evaporative cooling fans. If your fan shaft is rattling, wobbling, or running rough, worn bearings are a common cause — this part gets you back to smooth rotation.
The 1016-0100 pillow block bearing is built as a direct-fit maintenance part for PolarCool's 48" belt drive fan line, where shaft support quality determines how much vibration and wear your motor and belt see over time. A grease fitting is machined into the housing so you can extend service intervals without pulling the assembly apart. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
- Direct-fit pillow block bearing assembly for 48" PolarCool belt drive evaporative cooling fans.
- Compatible with 120V and 240V, 50Hz and 60Hz versions of the 48" belt drive fan.
- Also listed as compatible with 36" Single Speed Fans.
- Each fan requires 2 pillow block bearings for correct shaft support — order in pairs when both are worn.
- Grease fitting included for ongoing lubrication; not a sealed/maintenance-free bearing.
- NOT confirmed for direct-drive PolarCool coolers or fans outside the 48" belt drive and 36" Single Speed families — verify your fan's part number before ordering [NEEDS VERIFICATION].
- Grease fitting built into the housing for direct lubrication access.
- Direct-fit design matches PolarCool 48" belt drive mounting points — no drilling or fabrication.
- Durable housing construction intended for continuous-duty warehouse, outdoor, and industrial cooling use.
- Genuine PolarCool component, not a generic aftermarket substitute.
- Simple swap-and-lubricate installation reduces fan downtime during service.
