SF-1 vs SF-2: Which Self-Lubricating Bushing Is Right for Your Machine?
SF-1 and SF-2 bushings look almost identical on the outside. Both are three-layer steel-backed composite bearings. But their surface materials — PTFE versus POM — create two fundamentally different wear mechanisms, load profiles, and application windows. This article breaks down the material architecture, performance data, and real-world selection logic behind both types. It also shows how MYWAY’s SF-1 and SF-2 product lines are engineered for different operating conditions, and why getting the choice right saves you money on maintenance and downtime.
