Excellent durability

True oil-free performance
Needed a solution where oil contamination was a risk. These graphite plugs provide enough lubrication for our sliding applications. Very satisfied with the performance.

Perfect fit for our machinery
Ordered the 25mm variant for a retrofit project. The dimensions were precise and the installation was smooth. No need for additional grease which saves us maintenance time.

Good quality, tight tolerance
The quality of the copper alloy is top-notch. Just be aware the tolerance is tight, so ensure your shaft measurements are accurate before ordering. Otherwise, great product.
Q: What shaft tolerance is recommended for installation?

Q: Does this require any initial lubrication before use?
A: No, the graphite plugs provide immediate self-lubrication. You can install and operate immediately without adding oil or grease.
Q: Can these be cut to custom lengths?
A: Standard lengths are shipped as listed. For custom cutting services, please contact our sales team directly before placing your order.
Q: What is the warranty period for this item?
