Standard sizing confirmed

Measured all sizes with calipers; they adhere strictly to metric standards. No issues fitting them into standard housings. A reliable component for any workshop.

Good quality, slight variance

Overall very good quality. One of the M5 sleeves was slightly tight, but after a quick ream, it worked perfectly. Would buy again for general machinery repairs.

Perfect fit for my 3D printer

These brass bushings fit perfectly on my M8 rods. The oil impregnation seems genuine as they glide smoothly without additional grease. Great value for the price.

Fast shipping and great product

Needed specific M6 liners urgently. Arrived quickly and exactly as described. The self-lubricating feature saves me time on maintenance.

Decent but oily upon arrival

The bushings work well, but they arrived quite oily to the touch, which is expected for this type but required cleaning before installation in my clean room project.

Excellent wear resistance

Used these to replace worn-out plastic guides in a conveyor system. The brass holds up much better under constant friction. Highly recommended for industrial hobbyists.

5 FAQ

Q: Is the M16 size available in this specific listing?

A: Yes, this listing covers a range from M3 to M16. Please select the specific size variant you need from the dropdown menu before adding to your cart.

Q: How do I install these if they are a press fit?

A: For press-fit installations, ensure the housing bore is clean and slightly chamfered. Use an arbor press or a gentle hammer tap with a soft drift to avoid damaging the porous brass structure.

Q: Can these be used in outdoor applications?

A: While brass offers good corrosion resistance, these bushings are best suited for indoor or protected environments. Prolonged exposure to saltwater or harsh chemicals may degrade performance over time.

Q: Do these bushings require regular oiling?

A: No, these are oil-impregnated sintered brass bushings designed to be self-lubricating during normal operation. However, in high-load or extreme conditions, occasional external lubrication may extend their life.

Q: What is the tolerance level for the inner diameter?

A: The inner diameter typically follows an H7/H8 tolerance class suitable for sliding fits. For precision engineering projects, we recommend measuring your specific shaft before ordering.
