Frequently Asked Questions
Q: What sizes are available in this 5-piece brass bushing guide sleeve set?
A: The set is offered in multiple length options — 10mm, 12mm, 15mm, 18mm, 20mm, and 22mm — all with a consistent outer diameter (OD) of 18mm and inner diameter (ID) of 12mm. Please select your required length at checkout.
Q: Are these brass bushings self-lubricating?
A: Yes. These are oil-impregnated precision bushings, meaning the brass material retains lubricant within its structure, providing a low-maintenance, long-lasting bearing surface without constant re-oiling under normal operating conditions.
Q: What machines or projects are these brass guide sleeves compatible with?
A: These bushings are versatile and widely used in CNC machines, drill presses, lathes, jigs, fixtures, linear guides, and general mechanical assemblies where a smooth, precise shaft-to-housing interface is required.
Q: What is the surface finish quality of these bushings?
A: The inner bore surface roughness is Ra 0.8, which is a fine finish ensuring minimal friction, accurate shaft alignment, and a reliable fit for precision engineering applications.
