48A028 - Walter LINE-MATE III Grease Retaining Disc Replacement

Genuine OEM Maintenance Part for LINE-MATE III

The Walter 48A028 Grease Retaining Disc is a critical replacement component designed exclusively for the Walter LINE-MATE III linear finishing system. In high-performance surface finishing tools, maintaining the integrity of the gear housing is essential for longevity and consistent operation. This disc serves as the primary barrier within the spindle assembly, ensuring that the lubricating grease remains around the gears and bearings where it is needed most.

Over time, heat and vibration from heavy industrial use can cause seals and retaining discs to wear or deform. A compromised retaining disc can lead to grease leakage, which not only creates a mess in the workspace but, more critically, starves the internal mechanism of lubrication. This can lead to accelerated wear, overheating, and eventual tool failure. By installing a genuine Walter 48A028 disc, you restore the factory-specification seal, protecting your investment in the LINE-MATE III.

This part is manufactured to the exact tolerances required by Walter Surface Technologies, ensuring a perfect fit without the need for modification. It is an essential item for maintenance departments and tool repair specialists tasked with keeping linear finishing equipment in operational condition. Whether performing a scheduled overhaul or repairing a leak, this grease retaining disc is the correct specification for the Model 30-A 268 LINE-MATE III.

Technical Application

The disc is installed within the gear head assembly. It is recommended to inspect this component whenever the gear housing is opened for grease replenishment or bearing replacement. Failure to replace a worn disc can result in grease migration onto the abrasive drum or the workpiece, potentially ruining surface finishes.
