Durable and reliable

Using these in high-vibration equipment. They hold up well under stress and require no maintenance so far.

Good quality, slight shipping delay

The bushing itself is excellent quality and feels very durable. Only giving 4 stars because shipping took longer than expected.

5 FAQ

Q: What is the shaft tolerance recommendation?

A: We recommend a shaft tolerance of h9 for optimal fit and performance.

Q: Can you cut this to a custom length?

A: We offer custom machining services. Please contact sales for lengths other than the standard 50 mm.

Q: Do I need to add grease during installation?

A: No, this SF1 bearing is self-lubricating. However, a thin film of oil on the shaft can help initial run-in.

Q: Is this suitable for outdoor use?

A: Yes, the steel back features anti-corrosion plating suitable for most outdoor environments.

Q: What is the maximum rotational speed?

A: For continuous operation, we recommend a maximum surface speed of 2.5 m/s.
