Frequently Asked Questions
Q: What hardness contact wheel should I choose for metal polishing versus aggressive grinding?
A: For fine polishing and finishing work, a softer 55A durometer contact wheel conforms slightly to the workpiece for a smooth finish. For aggressive stock removal and coarse grinding, choose a harder 80A or 90A wheel to maximize cutting efficiency with your abrasive sanding belt.
Q: Are the bearings included with the contact wheel?
A: It depends on the option selected. Some configurations — such as the 6202-bare and 6005-bare options — include the circlip groove but require you to supply your own bearings. Other options (6201 installed, 6004 installed, 6204 installed, and the 6202 installed variants) come with bearings pre-fitted and ready to mount.
Q: What sanding belt size is compatible with this 250×50mm contact wheel?
A: This contact wheel is designed to work with abrasive sanding belts grit #36 through #1000, covering everything from heavy material removal to fine surface finishing. Always ensure your belt width matches the 50mm (2") face width of the wheel for optimal tracking and performance.
Q: Can this contact wheel be customized to fit a non-standard shaft size?
A: Yes — RAMS BRALIN offers custom inner hole configurations to suit unique shaft or axle dimensions. Contact us with your specific shaft diameter and bearing requirements, and we can fabricate a contact wheel tailored to your application.
