SF-1 Self Lubricating Sleeve Bearing Bushing 12mm – All Sizes

SF-1 Self Lubricating Composite Sleeve Bearing – 12mm Bore

Upgrade your mechanical assemblies with the SF-1 Series Self Lubricating Composite Sleeve Bearing by Kande Bearings. Engineered for low-friction, maintenance-free performance, these sleeve bushings feature a zinc alloy construction with a composite self-lubricating layer — ideal for rotating and oscillating applications where re-lubrication is impractical or impossible.

Available in a full range of lengths to suit your exact specifications, the SF-1 12mm bore series delivers consistent surface finish (Ra 0.8) and reliable dimensional accuracy straight out of the box. Ships in gold or silver finish — color does not affect functionality.

Key Features

• Self-Lubricating Design: Composite lining reduces friction and eliminates the need for ongoing lubrication maintenance.
• Zinc Alloy Material: Offers excellent wear resistance, strength, and dimensional stability under load.
• Precision Surface Finish: Ra 0.8 surface roughness ensures smooth shaft fit and long service life.
• Multiple Length Options: Choose from 5 mm to 25 mm lengths for versatile engineering applications.
• Compact 12mm Bore: Consistent 12 × 14 mm inner/outer diameter across all size variants for easy interchangeability.
• Dual Finish Available: Ships in gold or silver — if no preference is specified, color is assigned at random. Finish does not affect performance.

Frequently Asked Questions

Q: What does "self-lubricating" mean for these SF-1 sleeve bearings?

A: Self-lubricating sleeve bearings incorporate a composite lining (typically PTFE-based or similar material) embedded in the zinc alloy backing. This lining provides a continuous, low-friction interface between the shaft and the bushing — meaning you don't need to apply grease or oil periodically. The SF-1 Kande Bearings series is designed for long-term, maintenance-free operation in a wide range of mechanical applications.

Q: Which size should I choose for my application?

A: All sizes in the SF-1 12mm bore series share the same inner diameter (12 mm) and outer diameter (14 mm). The only variable is the length (5 mm to 25 mm). Select the length that best matches your housing depth or the axial load distribution required in your assembly. If you are unsure, measuring your existing bushing or housing bore depth is the best approach.

Q: Does the gold or silver finish affect the performance of the bushing?

A: No — the gold and silver finishes are purely cosmetic surface treatments and do not affect the dimensional accuracy, load capacity, surface roughness, or self-lubricating performance of the SF-1 sleeve bushing. If you have a preference, please note it at the time of purchase; otherwise a color will be shipped at random.

Q: Are these SF-1 bushings compatible with standard shaft sizes?

A: Yes. The SF-1 1205–1225 series is designed for a 12 mm nominal shaft diameter and a 14 mm housing bore, conforming to standard SF-1 composite bearing dimensional conventions. Always verify your shaft and housing tolerances before installation to ensure a proper press-fit and optimal performance.
