Multiquip 12779 Bearing, 85MM x 130MM, Flanged

The Multiquip 12779 Bearing, 85MM x 130MM, Flanged is a genuine OEM component designed for MD, HTX, STX, HHN, and HTN series ride-on power trowels. This bearing is sourced directly from Multiquip and meets the original equipment specification, ensuring a direct replacement in supported machines including MD105, MD80, HTX44K4, HTX44K5, STX55J6, STX55Y6, and HTN series models. When you need a verified, correct-fit bearing for your trowel, part number 12779 is the OEM answer. DHS Equipment supplies this part as an authorized Multiquip source, so you can order with confidence that you are receiving the correct component for your machine.

Key Features

• OEM-Specified Radial Load Capacity — Manufactured to Multiquip's original bearing specification, ensuring the correct load rating and dimensional tolerances for ride-on trowel rotor assemblies.
• Flanged Housing Design — The integrated flange locates and retains the bearing securely in the trowel's rotor or gearbox housing, allowing straightforward installation without improvised adapters.
• Broad Trowel Family Coverage — Fits MD105, MD80, HTX44, STX55, HHN, HTN, and additional Whiteman and international ride-on trowel models; confirm your model code before ordering.
• Smooth Blade Rotation — A correctly functioning bearing maintains consistent blade pitch control and rotor alignment; a worn bearing causes vibration, uneven finishing, and accelerated drivetrain wear.
• Genuine Multiquip OEM Part — Supplied under part number 12779 directly from the Multiquip parts network, not a generic substitute, so dimensional and material specs match the original component exactly.

A flanged bearing supports rotating shafts or rotor assemblies within the trowel's drive system, providing a low-friction pivot point while handling both radial and light axial loads. In a ride-on power trowel, bearings like the 12779 are critical to maintaining consistent blade rotation speed and accurate pitch adjustment across the full working width of the machine. When this bearing wears or fails, operators typically notice increased vibration, rougher surface finish quality, audible grinding from the rotor assembly, or loss of smooth blade response — all signs that the bearing needs immediate replacement to prevent further drivetrain damage.
