This MRCOOL Crossflow Fan Bearing Assembly is the replaceable bearing that supports the non-motor side of the blower fan in MRCOOL wall-mounted ductless mini split air handlers.

The shaft (pin) of the crossflow fan sits directly inside this bearing, allowing the fan to rotate smoothly, quietly, and efficiently. A worn or damaged bearing can cause noise, vibration, reduced airflow, or uneven fan operation.

Replacing this bearing restores proper fan alignment and helps extend the life of the blower assembly.

Key Features:

Supports the Cross Flow Fan:

The pin of the cross-flow fan fits directly inside this bearing assembly, ensuring it rotates smoothly and efficiently. This is essential for maintaining optimal airflow and the overall performance of your MRCOOL mini-split air handler.

Essential for Smooth and Quiet Operation:

This bearing assembly plays a key role in reducing operational noise by allowing the fan to spin with minimal friction. As a result, your MRCOOL ductless system will operate quietly while efficiently circulating air throughout the room.

Critical for Long-Term Reliability:

Constructed to withstand the wear and tear of regular use, the bearing is designed to handle the operational stresses of the air handler, ensuring durability and long-lasting performance. Regular maintenance and timely replacement of the bearing are essential for preventing wear-related issues and prolonging the lifespan of the air handler.

Part of the Fan Motor Assembly:

In MRCOOL ductless wall-mounted air handlers, this bearing is an integral component of the fan motor assembly. Without a properly functioning bearing, the fan could suffer from increased wear, reduced efficiency, and higher noise levels. Properly maintained, the bearing helps ensure that the fan continues to rotate freely and perform efficiently.

Common Symptoms of a Worn Bearing

  • Grinding or squealing noise
  • Fan wobble or vibration
  • Reduced airflow
  • Uneven or inconsistent operation

Replacing the bearing early can prevent damage to the blower motor and fan housing.

Application:

This bearing assembly is specifically designed for use in MRCOOL’s wall-mounted ductless mini-split systems, but it may also fit other brands or models. It is most commonly found in the following applications:

  • MRCOOL Ductless Wall-Mounted Air Handlers
  • Cross flow fan assemblies in mini-split systems

Maintenance and Replacement:

Regularly inspecting and replacing the bearing assembly as needed is crucial for maintaining the quiet, efficient operation of your air handler. Over time, the bearing can experience wear, leading to noisy or inefficient fan performance. Timely replacement can help avoid these issues and keep your mini-split running smoothly.

If the bearing mounting bracket tabs are cracked or brittle, replace the bracket at the same time to ensure the bearing stays properly seated. Link to mounting bracket

nice watch but expect what you pay for.
Color: A Gold, Color: A Gold
Pretty solid watch decent size face i prefer large face watches even with my small wrist. Its pretty good at staying synchronized. The case is pretty solid but closer inspection makes it look cheap, i still love though and it does get a lot of looks. The band is my really only big complaint it feels chintsy and cheap, the clasp spring fellout once but very simple to re-insert and if you have small wrist like me its definite resize. Other than that for the price its a cool mechanical watch.

my wrist is almost 9 inches so some choices are too small. plus I like a slightly loose fit rather than snug. it's beautiful just like the pictures. happy with it.
