OVERVIEW

Restore Your Line-Mate Performance with the Walter 48R344 Rubber Sleeve

The Walter 48R344 Rubber Sleeve is an essential replacement component designed specifically for the Walter 14-E 144 Expanding Drum, a core accessory of the Line-Mate III linear finishing system. Over time and through rigorous industrial use, the rubber components of expanding drums can wear down, lose their elasticity, or develop surface cracks. This degradation can lead to belt slippage, uneven finishing, and safety hazards. The 48R344 sleeve restores your drum to factory-new condition, ensuring optimal performance for all your metal finishing tasks.

Engineered from high-grade industrial rubber, this sleeve is built to withstand the heat and centrifugal forces generated during high-speed sanding and polishing. Its primary function is to expand under rotation or mechanical tightening, creating a firm, non-slip interference fit with abrasive belts (such as Topcut or Blendex belts). This secure grip is vital for transferring the tool's power to the workpiece efficiently, allowing for consistent scratch patterns and uniform material removal.

Installation is straightforward, allowing operators to quickly swap out worn sleeves and minimize downtime. By maintaining the integrity of your expanding drum with a genuine Walter replacement sleeve, you ensure that your Line-Mate tool continues to deliver the professional-grade linear finishes required in stainless steel fabrication, pharmaceutical equipment manufacturing, and food processing industries. Whether you are graining, polishing, or cleaning, a fresh rubber sleeve is the key to a chatter-free and flawless finish.

FAQ

The 48R344 is designed to fit the Walter 14-E 144 Expanding Drum, which measures 3-1/2 inches in diameter and 4 inches in width.

You should replace the sleeve if you see visible cracks, if the rubber has hardened and glazed, or if abrasive belts begin to slip during use despite proper tightening.

It is manufactured specifically for Walter Surface Technologies equipment. While it may fit other drums with identical dimensions (3.5" x 4"), we recommend using it only with the specified Walter drum for safety and performance.

No, this SKU (48R344) is for the replacement rubber sleeve only. The complete expanding drum assembly is sold separately.

This sleeve is used on the expanding drum accessory for the Walter Line-Mate III linear finishing tool.

The rubber is durable, but Walter Line-Mate tools are typically used for dry finishing. Consult the tool's manual regarding wet applications to avoid electrical hazards or damage.

The old sleeve is removed from the drum core (often by cutting it off if it's fused, or sliding it off if loose), and the new sleeve is slid onto the core. Ensure the drum is fully relaxed/unexpanded during installation.
