Good value
Quality is good but shipping took a while. Product itself is solid and functions as expected in our machinery.

Durable and precise
Fit was tight but correct according to specs. Running smooth after a short break-in period. Excellent quality copper.

Bulk order success
Ordered 50 units for our assembly line. Consistency across all parts is excellent. No failures so far.
Q: Is the flange integral to the sleeve?
A: Yes, it is a solid-inlaid single-piece construction.
Q: Does this require external grease?
A: No, the graphite plugs provide continuous lubrication without external grease.
Q: Is there a break-in period?
A: A short run-in at low speed is recommended for optimal performance.
Q: Can this be modified after purchase?
A: We do not recommend machining as it may disrupt the graphite inlays.
Q: What is the hardness rating?
A: Approximately HB 90-110 depending on the specific alloy batch.
