The Wacker Neuson Woodruff Key is a genuine OEM component designed for BPS series and A5000/160B plate compactors, including the BPS1030B, BPS1135B, BPS1340B, BPS1550B, BPS2050B, and their Bw variants. As a direct factory replacement, this Woodruff Key is manufactured to the exact specifications required by Wacker Neuson, ensuring the shaft and hub assembly seats and locks correctly every time. Sourcing part number directly from the OEM lineup means you get a component that fits without guesswork, keeping your compactor back in service fast.
Key Features
- OEM Dimensional Accuracy — Manufactured to Wacker Neuson's exact key profile and tolerancing, so the shaft-to-hub engagement locks securely without slop or stress concentration.
- Drop-In Installation — Seats directly into the existing keyway on BPS series compactors; no filing, shimming, or fitting required before assembly.
- Broad BPS Series Coverage — Compatible with the BPS1030B, BPS1135B, BPS1340B (including Black Edition), BPS1550B, BPS2050B, their Bw variants, and the A5000/160B.
- Prevents Shaft and Hub Damage — A correctly sized Woodruff Key transfers torque evenly between the shaft and hub; an undersized or worn key allows rotational slippage that rapidly damages both mating surfaces.
- Genuine Wacker Neuson OEM Part — Sourced directly from the manufacturer, so material grade and geometry match the original component that left the factory.
A Woodruff Key is a small, semicircular metal key that fits into a matching slot — called a keyway — machined into both a rotating shaft and the hub of a component such as a pulley, flywheel, or eccentric weight. Its job is to lock those two parts together rotationally, ensuring torque is transferred cleanly from the shaft to the driven component rather than allowing them to slip against each other. When a Woodruff Key wears, shears, or goes missing entirely, the shaft and hub lose their positive drive connection — the result is lost eccentric force in a plate compactor, which means reduced or uneven compaction output and accelerating wear to the keyways themselves if the machine continues to run.
