Good quality, fast shipping

The bushing feels solid and well-made. The bronze backing provides good strength. Only giving 4 stars because the packaging was slightly damaged, though the product was fine.

Reliable for heavy machinery

Purchased for our excavator maintenance. The load capacity is impressive, and it handles the dust and debris without seizing up.

Perfect fit for hydraulic repair

Ordered these for a hydraulic cylinder rebuild. The dimensions were exact, and the self-lubricating feature saved us time on installation. Very smooth operation after testing.

Great value for money

Compared to OEM parts, these are significantly cheaper but perform just as well. The oil-impregnated layer works exactly as described.

Solid component

Does the job well. Installation required standard pressing tools. No squeaking or binding during initial run-in period.

Excellent wear resistance

We use these in high-vibration environments. After three months of continuous use, there is virtually no sign of wear. Highly recommend for industrial applications.

5 FAQ

Q: Can this be cut to a custom length?

A: Yes, the material can be machined or cut to custom lengths using standard metalworking tools, provided you deburr the edges afterward.

Q: What is the lead time for bulk orders of 500 units?

A: For orders over 100 units, please contact our sales team directly. Standard bulk orders typically ship within 5-7 business days from our warehouse.

Q: What is the maximum pressure this bearing can withstand?

A: The static load capacity is up to 250 N/mm², and the dynamic load capacity is approximately 140 N/mm², depending on the sliding speed.

Q: Is this bushing suitable for underwater applications?

A: While the material is corrosion-resistant, this specific SF-1 composite is designed for general industrial use. For constant submersion, we recommend checking our marine-grade series.

Q: Do I need to add extra grease during installation?

A: No, the bushing comes pre-impregnated with lubricant. Adding extra grease is not necessary unless specified for extreme operating conditions.
