It distributes clamping force evenly across the wheel face, preventing slippage, reducing vibration, and protecting the wheel bore from damage. The 4mm step height on this flange ensures the wheel is centered and held securely on the spindle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: What spindle size does this flange fit?\u003c\/strong\u003e\u003cbr\u003eA: This arbor washer flange is designed for bench grinder and polisher spindles with a \u003cstrong\u003e10mm shaft diameter\u003c\/strong\u003e. Verify your machine's spindle size before ordering. For other spindle sizes, see our full range of machine accessories.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Is this flange compatible with both buffing and grinding wheels?\u003c\/strong\u003e\u003cbr\u003eA: Yes — this flange is suitable for buffing, polishing, and light grinding wheels mounted on 10mm spindle bench grinders. For heavy-duty abrasive grinding, always confirm your wheel's maximum RPM rating matches your machine's operating speed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Do I need a matching flange on both sides of the wheel?\u003c\/strong\u003e\u003cbr\u003eA: For most bench grinder setups, a flange is used on both sides of the wheel (inner and outer) to ensure balanced clamping. Check your machine's existing hardware and order accordingly.
