The Multiquip 51215 Steel Ball RW-1404MR is a genuine OEM steel ball designed for RAMMAX walk-behind roller models including the RW1404MR, RW1504HF (up to S/N ), RW1403HF, RW1404MR (S/N 326075 and up), and P33/24 FR/FC/FCR and P33/24 HHMR-BD with blade series. Sourced directly from Multiquip, part 51215 meets the exact material and dimensional specifications of the original component. This is a direct-fit OEM replacement that installs without alteration, ensuring your roller returns to service correctly. Keep part number 51215 on hand as a standard service item for any RAMMAX roller in your fleet.
Key Features
- Genuine OEM Steel Grade — Manufactured to the same hardness and dimensional tolerance as the original ball, ensuring consistent load-bearing performance within the roller assembly.
- Direct-Fit Replacement — Engineered to seat precisely within the existing bearing or drive interface, requiring no re-machining or shimming on installation.
- Broad RAMMAX Roller Compatibility — Confirmed fitment across RW1404MR, RW1504HF (up to S/N 1534188), RW1403HF, RW1404MR (S/N 326075 and up), and the P33/24 FR/FC/FCR and P33/24 HHMR-BD with blade series.
- Sustained Drive Integrity — A correctly sized steel ball maintains smooth rotational transfer and prevents premature wear on adjacent bearing surfaces; a worn or undersized ball leads to play in the assembly and accelerated component damage.
- Verified OEM Part Number — Part number 51215 matches Multiquip's official parts documentation, eliminating guesswork when ordering for specific serial number ranges.
A steel ball of this type functions as a precision load-transfer element within a bearing or drive mechanism, allowing controlled rotation or movement between mating surfaces while carrying radial or axial loads. In a walk-behind roller, these balls are critical to maintaining smooth drum rotation and consistent compaction output — even minor wear or size variation introduces looseness that can affect tracking and surface finish quality. When a steel ball wears beyond tolerance or fails, the surrounding races or housing surfaces suffer accelerated damage, making timely replacement the most cost-effective approach to component maintenance.
