Key Features
- OEM-Grade Sealing Material — Manufactured to the original compound and dimensional specification for the 38x52x8 2G40 profile, maintaining correct compression and contact pressure against rotating shafts.
- Direct Drop-In Installation — Matches the original bore, shaft diameter, and lip configuration for straightforward replacement without rework or modifications to the housing.
- Broad RAMMAX Roller Compatibility — Fits RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188) walk-behind rollers.
- Prevents Lubricant Loss and Contamination — A properly functioning oil seal keeps lubricant retained at the shaft and blocks dirt, water, and debris from entering bearing cavities, protecting internal components from accelerated wear.
- Genuine Multiquip OEM Part — Supplied under part number 50311200 directly from the Multiquip parts network, ensuring full traceability and part number accuracy.
An oil seal creates a dynamic barrier between a rotating shaft and a stationary housing, keeping lubricating oil contained within the assembly while preventing external contaminants from entering. In a walk-behind roller, these seals are critical at drum drive shafts and gearbox outputs where constant rotation and exposure to water and compacted material put steady demands on the sealing lip. When an oil seal wears out or is damaged, lubricant leaks out and abrasive material works its way in, leading to premature bearing and gear failure that can sideline the machine entirely.
