Walter Lower Flange for 7-Inch and 9-Inch Grinders

Essential Hardware for Angle Grinders

Keep your grinding equipment running at peak performance with the Walter 48T001 Lower Flange. This replacement part is an indispensable accessory for professional welders and fabricators who rely on 7-inch and 9-inch angle grinders for daily tasks. The lower flange, often referred to as the inner flange or backing flange, sits directly on the grinder's spindle and provides the necessary support for Type 27 depressed center wheels.

Over time, flanges can become worn, nicked, or lost during wheel changes. A damaged flange can cause the abrasive wheel to sit unevenly, leading to dangerous vibrations, premature wheel failure, or even shattering during use. Replacing your hardware with the 48T001 ensures that your equipment meets safety standards and operates smoothly. This unit is designed for standard 5/8"-11 spindles, making it a versatile part for many heavy-duty grinders in the industrial sector.

Durability and Performance

Walter Surface Technologies is known for producing high-performance abrasives and power tools. This flange reflects that commitment to quality. It is machined to precise tolerances to ensure the wheel is centered exactly on the axis of rotation. This balance is crucial when spinning large 9-inch wheels at thousands of RPM. The robust metal construction resists the crushing force applied by the clamping nut, maintaining its shape through countless wheel changes.

Installation

Installation is straightforward: simply slide the 48T001 onto the spindle before placing your grinding disc. Ensure the raised shoulder (if applicable for the specific wheel type) or the flat surface is oriented correctly according to the wheel manufacturer's instructions. This simple component is the foundation of your grinder's drive assembly.
