Dillon SDB Primer Slide Bushing

• Factory replacement fit: Made for the Square Deal B primer slide assembly, this part matches the original dimensions so the press keeps its intended primer-feed timing and movement.
• Smoother primer slide travel: The bearing supports consistent movement of the primer slide, helping reduce drag that can interrupt priming and slow down a loading session.
• Reliable priming function: A correctly fitted primer slide bearing helps the primer system cycle the same way from stroke to stroke, which matters for steady operation on a progressive press.
• Simple maintenance part: As a dedicated replacement component, it is useful for restoring worn or damaged primer-slide hardware without replacing the full assembly.
• Made in USA: Built by Dillon Precision in the United States, it suits reloaders who want original factory parts for ongoing press maintenance.

About the Dillon Precision Series

Dillon Precision replacement parts are intended to keep the company’s reloading presses working as designed, with factory-correct fit across specific assemblies and machine families. In Dillon’s lineup, these parts support routine maintenance, repair, and long-term service of progressive presses used by handloaders who value steady output and repeatable operation. Rather than changing how a machine works, the goal is to restore the original function of important systems such as indexing, priming, powder delivery, and case handling.

Within that broader range, Square Deal B parts are especially relevant to reloaders running a compact progressive press for handgun cartridges. Components tied to the primer system matter because progressive loading depends on each station working in sequence without hesitation. Small parts such as bearings, pins, springs, and bushings help maintain that sequence by supporting smooth movement and correct alignment. For owners who prefer to service their own equipment, factory parts keep the machine close to its original setup and reduce guesswork when replacing worn items.

About the Dillon SDB Primer Slide Bushing

The Dillon SDB Primer Slide Bushing is a replacement part for the Square Deal B primer slide assembly, where dependable movement is essential to consistent priming. In a progressive reloading press, the primer system has to cycle cleanly on every handle stroke. A small wear part in this area can have an outsized effect on how smoothly the press runs, especially during longer loading sessions. By restoring the original support point within the assembly, this component helps the primer slide move with the controlled, repeatable action the machine was designed to deliver.

That matters in practice because primer-feed issues rarely stay isolated to one station. Extra drag, inconsistent travel, or a worn support surface can interrupt rhythm and force unnecessary troubleshooting. Replacing the bushing is a straightforward way to address one of the contact points in the system before it affects overall workflow. As an original Dillon Precision part, it is intended for proper compatibility rather than universal fit, which is important on a press where timing and alignment influence the entire loading cycle.

For reloaders maintaining an older machine or keeping a frequently used press in service, this part makes sense as preventive maintenance as well as repair. Its role is simple, but the benefit is practical: smoother primer-slide operation, more predictable press behavior, and less interruption when loading handgun ammunition on the Square Deal B.
