Trane BRG1546 Bearing

Engineered for high-load industrial and commercial HVAC applications, the Trane BRG1546 (now superseded by BRG01546) is a precision-machined pillow block bearing designed to support rotating shafts with a 1 7/16-inch bore diameter. This OEM replacement part features a rugged two-bolt cast iron housing and high-grade steel balls to ensure maximum durability and minimal friction during high-RPM operation. As a standard duty ball bearing, it is frequently utilized in Trane air handlers and rooftop units like the TWE240B and SEHCC4000 series, providing critical shaft support for blower assemblies. The unit includes a integrated grease fitting for manual lubrication and is equipped with a contact seal with flinger to prevent particulate ingress, protecting the internal raceways in demanding mechanical environments. For contractors handling HVAC repair or preventive maintenance, this pillow block bearing 1 7/16 ensures exact fitment and shaft alignment, preventing premature drive belt wear and reducing vibration in the fan housing assembly.

• OEM Precision: Genuine Trane replacement ensures exact dimensional compatibility with original shaft tolerances.
• Heavy-Duty Construction: The cast iron housing provides superior stability and vibration dampening for industrial HVAC applications.
• Contamination Protection: Integrated contact seals with flingers protect steel balls from dust and moisture.
• Ease of Maintenance: Equipped with a standard grease fitting for routine lubrication to extend the service life of the mechanical parts.
• Drop-in Replacement: Standard 2-bolt mounting pattern for rapid installation on common Trane HVAC equipment.

What is the difference between BRG1546 and BRG01546?
BRG1546 is the legacy part number. The manufacturer has updated the designation to BRG01546, which is the direct functional replacement with identical technical specifications, including the 1 7/16-inch bore.

Which models are compatible with this bearing?
This bearing is commonly installed in Trane and American Standard air handling units, specifically models like the TWE240, SAHFF300, and SEHCC4000, where a 1-7/16 inch shaft is utilized in the drive assembly.

Does this bearing require manual lubrication upon installation?
While these units often arrive pre-lubricated, a veteran HVACR technician should verify grease levels through the integrated fitting before final commissioning to ensure optimal thermal performance and friction reduction.
