The Multiquip 3-12765 is a genuine OEM Bearing Flange RW-3015 P54/KA/KA4B designed for RAMMAX ride-on roller models KA4B and RW-3015. As a factory-original component, this bearing flange meets the exact tolerancing and load specifications required to maintain proper drum alignment and rotation on these machines. Sourced directly through Multiquip's OEM supply chain, 3-12765 ensures correct fitment without the guesswork of cross-referencing aftermarket alternatives. If you're servicing a KA4B or RW-3015 roller, this is the correct part to specify.
Key Features
- OEM-Grade Load Tolerancing — Manufactured to the exact radial and axial load ratings required for drum-support applications on RAMMAX roller equipment, ensuring consistent bearing performance under compaction stress.
- Direct Bolt-In Replacement — Matches the original flange bolt pattern and bearing bore dimensions, allowing straightforward installation in the existing drum housing without re-machining or shimming.
- Confirmed Fitment for KA4B and RW-3015 — Verified for use on Multiquip RAMMAX roller models KA4B and RW-3015, eliminating compatibility uncertainty on these specific machines.
- Supports Drum Stability Under Load — A correctly functioning flange bearing holds the drum shaft in precise alignment; a worn or failed unit causes lateral drum movement, uneven compaction patterns, and accelerated wear on adjacent components.
- Genuine Multiquip OEM Part — Supplied as an authentic Multiquip replacement, carrying part number 3-12765 to confirm traceability back to the original equipment specification.
A bearing flange serves as the structural interface between a rotating shaft and the machine's frame or drum housing, combining a precision bearing with a mountable flange plate in a single assembly. On ride-on rollers like the KA4B and RW-3015, this component supports the drum shaft and absorbs both radial forces from the drum's weight and axial forces generated during compaction passes. When the bearing flange wears or fails, the drum shaft loses its centered position, leading to vibration, noise, uneven surface compaction, and potential damage to the drum housing itself.
