The Wacker Neuson is a genuine OEM Needle Roller Bearing HK1712 designed for CT36 and CT48 series walk-behind concrete power trowels. Sourced directly from Wacker Neuson, this bearing meets the original design tolerances for the trowel's rotating drive components. It is confirmed compatible with multiple CT36 and CT48 configurations, including the CT36-5A, CT36-5A-C, CT36-6, CT36-X, CT36-X-C, CT48-8A, CT48-9, and their respective EU variants. Ordering by part number ensures you receive the correct HK1712-spec needle roller bearing for your machine.
Key Features
- Precision Needle Roller Construction — The HK1712 needle roller profile delivers the high radial load capacity and minimal radial footprint required in the trowel's compact drive assembly.
- Genuine OEM Component — Manufactured to Wacker Neuson's original specification, ensuring the bearing matches the exact bore, outer diameter, and width of the factory-installed unit.
- Broad CT-Series Compatibility — Fits CT36 and CT48 walk-behind power trowel families across multiple build configurations, including EU-spec and adjustable-handle variants.
- Smooth, Consistent Blade-Speed Transfer — A correctly functioning needle roller bearing allows the trowel's rotor shaft to spin freely and evenly, producing a consistent finish quality across the concrete surface.
- Drop-In Replacement — The HK1712 bearing installs into the existing housing with no modifications to surrounding components, simplifying the repair and getting your trowel back to work faster.
A needle roller bearing supports the rotating shaft inside the trowel's gearbox or spider assembly by using a ring of small-diameter cylindrical rollers to carry radial loads with very little friction. Because the rollers have a high surface-contact area relative to their compact size, they handle the cyclical loads generated during finishing passes without allowing shaft flex or lateral play. When this bearing wears or fails, operators will typically notice increased vibration, audible grinding, uneven blade rotation, or heat buildup in the drive housing — all of which affect finish quality and can lead to more extensive drivetrain damage if left unaddressed.
