48H404 - Walter Line-Mate Nylon Spacer Washer

Essential Mounting Accessory for Linear Finishing

The Walter 48H404 Nylon Spacer is a critical component designed for use with Walter Surface Technologies' renowned linear finishing systems, specifically the Line-Mate family of tools. When working with high-performance surface finishing equipment, precision is paramount. This spacer serves a vital function by adjusting the fit of abrasive drums, wheels, and flap rolls onto the tool's arbor. Without the correct spacing, accessories may not sit flush or securely, leading to vibration, poor finish quality, or potential safety hazards during operation.

Manufactured from high-quality industrial nylon, this spacer offers distinct advantages over metal alternatives. Nylon is naturally resistant to corrosion, oils, and many workshop chemicals, ensuring it maintains its integrity even in harsh industrial environments. Furthermore, its non-marring properties protect the metal components of your expensive power tools. It acts as a buffer, preventing direct metal-on-metal contact that could lead to fretting or wear on the spindle assembly. This is particularly important when frequently changing between different grits or types of abrasive media.

Optimized for the Line-Mate System

The Line-Mate III is a versatile tool used for graining, polishing, and brushing metals. It accommodates a wide variety of consumables, from pneumatic drums to flap wheels. However, not all consumables have the same core width. The 48H404 Nylon Spacer allows operators to adapt the effective length of the spindle to match the specific accessory being used. Whether you are mounting a narrow wire brush or a standard abrasive drum, this spacer ensures the locking nut can apply the necessary torque to hold the item firmly in place without running out of thread.

Genuine OEM Quality

Using genuine Walter parts like the 48H404 guarantees compatibility and performance. Generic washers may not have the precise inner diameter or thickness required for the Line-Mate arbor, potentially causing imbalance. An unbalanced tool causes operator fatigue and uneven wear on the abrasive. By choosing the OEM nylon spacer, you ensure that your equipment runs smoothly, extending the lifespan of both the tool and the consumables. It is a small but indispensable part of your surface finishing toolkit.
