Wacker Neuson 5000117978 Cylindrical Roller Bearing NJ211 C3

The Wacker Neuson Cylindrical Roller Bearing NJ211 C3 is a genuine OEM component designed for the RD7 series walk-behind tandem rollers, including the RD7H-ES and RD7H-S models. As a direct factory replacement, it meets the original engineering tolerances and load ratings specified for these double-drum vibratory rollers. The C3 internal clearance designation ensures the bearing performs correctly under the elevated operating temperatures and dynamic radial loads generated during compaction work. Confirm your machine's model number before ordering to ensure a proper application match.

Key Features

• OEM-Grade Radial Load Capacity — Genuine Wacker Neuson part manufactured to the precise cylindrical roller geometry and C3 clearance specification required for the drum drive and vibration system loads in RD7 series rollers.
• NJ211 C3 Profile — Drop-In Fitment — The NJ211 designation matches the original bearing's bore, outer diameter, and width, allowing direct installation without modification to the housing or shaft.
• RD7 Series Compatibility — Verified fitment across the RD7H-ES, RD7H-S, and RD7 double-drum vibratory roller variants, including both EU and standard configurations.
• C3 Clearance for High-Temperature Operation — The C3 internal clearance specification accommodates thermal expansion during extended compaction runs, preventing bearing seizure under sustained vibration and load cycles.
• Protects Drum Drive Integrity — A worn or failed roller bearing causes excessive shaft play, uneven drum rotation, and accelerated wear to surrounding drivetrain components — replacing it promptly restores smooth, consistent drum operation.

A cylindrical roller bearing supports radial loads on a rotating shaft by distributing force across a set of precision-ground cylindrical rollers rather than balls, making it well-suited to the high radial demands found in vibratory compaction equipment. In the RD7 series tandem roller, this bearing supports the drum drive shaft and must withstand continuous vibration, shock loading, and heat generated during asphalt and soil compaction passes. When the bearing wears or loses internal clearance, operators will typically notice increased noise from the drum assembly, vibration anomalies, or uneven compaction output — all signs that the bearing needs immediate replacement to avoid cascading damage to the drivetrain.
