Fitment is confirmed for the RD7 Tandem Roller and RD7A Tandem Roller, making it the correct choice when servicing these walk-behind compaction machines.

Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's exact tolerances, ensuring the collar seats and retains correctly without play or misalignment in the assembly.
- Drop-In Installation — Engineered as a direct replacement that aligns with existing mounting points on the RD7 and RD7A, so there is no reworking of surrounding components during installation.
- Confirmed Fitment for RD7 and RD7A Tandem Rollers — Verified for the RD7 Tandem Roller and RD7A Tandem Roller series, covering multiple machine configurations within that family.
- Maintains Drum and Drivetrain Integrity — A correctly fitted collar holds rotating or sliding components in their designed position; a worn or missing collar can introduce unwanted movement that accelerates wear on adjacent parts.
A collar is a mechanical retaining component used to secure, locate, or limit the movement of rotating or sliding shafts and assemblies. In the context of a tandem roller like the RD7 and RD7A, collars play a critical role in keeping drivetrain or drum-related components properly positioned under the continuous vibration and load cycling that compaction work demands. When a collar wears, cracks, or loses its fit, adjoining components can shift out of alignment, leading to accelerated wear, noise, or loss of control over the compaction mechanism.
