Wacker Neuson 34835 Needle Bearing

The Wacker Neuson 34835 Needle Bearing is a genuine OEM component designed for the BS50-2, BS50-2i, BS60-2, BS60-2i, BS70-2, BS70-2i vibratory rammer series, as well as BH 22, BH 23, BH 24, BH 40, BH 55, and BH 65 gasoline breaker models. As a direct OEM replacement, part 34835 is manufactured to the same specification as the original, ensuring a correct fit without modification. This bearing is used across a wide range of Wacker Neuson rammer and breaker configurations, including standard, oil-injected, variable speed, and high-altitude variants.

Key Features

• Genuine OEM Construction: — Manufactured to Wacker Neuson's original tolerance and load-rating specs, so the bearing seats and rotates exactly as the original did in service.
• Direct Drop-In Replacement: — Matches the original bearing journal dimensions on BS-series rammers and BH-series breakers, installing into the existing housing without machining or adaptation.
• Broad Fitment Across BS and BH Families: — Compatible with BS50-2, BS60-2, BS70-2, BS65-V, and legacy BS500/BS600/BS700 rammers, plus BH 22 through BH 65 gasoline breakers in standard and low-vibration configurations.
• Sustained Power Transmission: — A properly functioning needle bearing keeps the crankshaft or drive shaft rotating freely under the high-impact, high-frequency loads these machines generate; a worn bearing causes vibration, heat buildup, and accelerated shaft wear.
• Built for High-Cycle Demand: — The needle-roller design distributes radial loads across a large contact area relative to the bearing's compact size, making it well suited to the continuous reciprocating stress of rammer and breaker operation.

A needle bearing is a type of roller bearing that uses long, thin cylindrical rollers arranged radially around a shaft. In vibratory rammers and gasoline breakers, needle bearings support rotating or oscillating shafts — such as the crankshaft or connecting-rod journal — under high radial loads in a very confined space. Because these machines operate at high impact frequency, the bearing is subjected to constant cyclic stress; when it begins to wear, the shaft develops play, which degrades compaction or breaking energy and accelerates damage to surrounding components. Replacing the needle bearing at the first sign of roughness, noise, or excess shaft movement restores proper power transfer and protects the crank assembly from secondary wear.
