Wacker Neuson 5002001291 Ext Retaining Ring 20Mmx1.2Mm

The Wacker Neuson Ext Retaining Ring 20Mmx1.2Mm is a genuine OEM component designed for a wide range of Wacker Neuson cut-off saws, power cutters, electric breakers, vibratory plates, floor saws, and frequency converters. Sourced directly from Wacker Neuson, part meets the exact dimensional and material standards of the original, ensuring a consistent, trouble-free installation. This ring fits key model families including the BTS 630, BTS 635, BTS 930, BTS 935, BTS 1030, BTS 1035, BTS 1140 L3, EH 23, EH 25, EH 27, EH 50, EH 75, DPS vibratory plates, BFS floor saws, BS60Y rammers, and FU series frequency converters.

Key Features

• Precision Dimensional Tolerancing — Manufactured to the exact 20mm diameter and 1.2mm groove specification, ensuring the ring seats securely and holds shaft or housing components in their correct axial position.
• Genuine OEM Part — Supplied by Wacker Neuson as a factory-authorized replacement, so the metallurgy, hardness, and spring tension match the original part installed on the production line.
• Broad Cross-Equipment Fitment — A single part number covering BTS cut-off saw and power cutter series, EH electric breaker series, DPS vibratory plates, BFS and DFS floor saws, BS60Y rammers, and FU frequency converters — verify your model number before ordering.
• Retains Critical Shaft Components — A correctly fitted external retaining ring prevents axial movement of rotating or reciprocating assemblies; a worn or missing ring can allow components to walk out of position, leading to rapid wear or mechanical failure.
• Direct Drop-In Replacement — The 5002001291 installs into the existing external groove using standard snap-ring pliers, with no machining or adaptation needed to fit the original groove geometry.

An external retaining ring is a thin, sprung metal clip that snaps into a machined groove on the outside of a shaft or pin to prevent components from sliding off axially. In equipment like cut-off saws and electric breakers, these rings lock bearing races, drive components, or arbor assemblies in place during high-vibration operation. When a retaining ring becomes fatigued, distorted, or missing entirely, the parts it was holding can shift or separate — causing accelerated wear on adjacent components and potentially rendering the machine unsafe to operate.
