The Multiquip RB252931 External Lockwasher (5/8") JB5090 is a genuine OEM component designed for Jimmy Series equipment. Sourced directly from Multiquip, this lockwasher is manufactured to the exact dimensions and material grade required for proper fastener retention on your machine. Confirm RB252931 against your parts manual or serial tag before ordering to ensure a correct match for your Jimmy Series unit.
Key Features
- OEM-Grade Material: — Manufactured to the same hardness and tooth profile specification as the original, ensuring consistent clamping force and resistance to loosening under vibration.
- Direct-Fit Installation: — Sized at 5/8" to seat correctly on the mating fastener without rework, shimming, or modification to the surrounding hardware.
- Jimmy Series Compatibility: — Engineered specifically for Jimmy Series equipment; cross-reference part number RB252931 with your machine's parts breakdown for confirmed fitment.
- Vibration Resistance: — The external tooth design bites into both the bearing surface and fastener, maintaining clamp load through the high-vibration operating cycles common to Multiquip equipment.
- Fastener Integrity: — A worn or missing lockwasher allows fasteners to back out during operation, leading to loosened assemblies, accelerated wear on mating components, and potential mechanical failure.
An external lockwasher is a hardened, toothed retaining ring placed under a bolt head or nut to prevent loosening caused by vibration, torque, or thermal cycling. The external teeth bite into both the fastener bearing surface and the workpiece, creating mechanical resistance that keeps the fastener from rotating back. When a lockwasher is missing, deformed, or worn flat, fasteners can gradually back out during normal machine operation, compromising the integrity of the entire assembly it secures.
