Smooth Operation

Very low friction compared to our previous metal bushings. The machinery runs much quieter now.

Good Value

Works well for the price. The fit was slightly tighter than expected but settled in after a short break-in period.

5 FAQ

Q: What is the current lead time for bulk orders?

A: Standard sizes ship within 24 hours. Bulk orders over 100 units may require 3-5 business days for processing.

Q: Does this bushing require external lubrication?

Q: What shaft tolerance is recommended for installation?

A: We recommend an h9 shaft tolerance for optimal fit and performance with this inner diameter.

Q: Can I cut this tubing to a custom length?

A: Yes, you can cut it to size using a fine-tooth saw or a tubing cutter for a clean edge.

Q: Is this resistant to acidic environments?

A: PTFE offers excellent resistance to most acids and chemicals. Please consult the chemical compatibility chart for specific substances.
