The Wacker Neuson is a genuine OEM Slide Bearing designed for the BH-series gasoline breakers, including the BH 23, BH 24, BH 40, BH 55, BH 55rw, BH 65, and related variants. Sourced directly from Wacker Neuson, this part carries the same specifications as the original component installed at the factory, ensuring a direct, trouble-free installation. Compatibility spans an extensive range of BH-series models across multiple configurations — including standard, low-vibration, reverse-stroke, and regional variants — making this one of the most widely applicable service parts in the BH breaker lineup. Always confirm your machine's model number before ordering to ensure correct fitment.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional specifications for the slide bearing bore, ensuring the correct load-bearing surface hardness and fit within the breaker cylinder.
- Direct Drop-In Replacement — Engineered to match the original bearing seat geometry in BH-series breakers, so the part seats correctly without modification or shimming during reassembly.
- Broad BH-Series Coverage — A single part number covers BH 23, BH 24, BH 40, BH 55, BH 55rw, BH 65, and multiple sub-variants including Low Vib, RS, and regionally configured models.
- Maintains Smooth Piston Travel — A correctly functioning slide bearing keeps the reciprocating piston aligned and moving freely; a worn bearing causes lateral play, accelerated cylinder wear, and loss of impact energy.
- Fuel System and Strike-Mechanism Integrity — Proper bearing clearance is critical to consistent combustion timing and strike force in gasoline-powered breakers; an out-of-spec bearing degrades both output and fuel efficiency.
The slide bearing in a BH-series gasoline breaker acts as the primary guide and low-friction support surface for the reciprocating piston as it travels through the cylinder bore. By maintaining precise alignment between the piston and cylinder wall, it minimizes metal-to-metal contact and allows the full energy of each combustion cycle to transfer into the tool shank rather than being lost to friction or lateral movement. When the slide bearing wears beyond its service limit, piston wobble increases, cylinder surfaces erode prematurely, and the breaker's overall impact performance drops noticeably — making timely bearing replacement one of the most cost-effective ways to restore full tool output.
