Key Features
- Eccentric Locking Collar: Provides 360° secure shaft grip with superior resistance to loosening under vibration and shock loads, outperforming traditional set-screw locking mechanisms.
- Extended Inner Ring (B=49.2mm): Increases load distribution area and shaft support, reducing stress concentration and extending bearing service life.
- Double Lip 2F Seals: Advanced sealing technology prevents contaminant ingress while retaining lubrication, ideal for dusty agricultural and industrial environments.
- High Load Capacity: Dynamic load rating of 33.2 kN and static load rating of 20.4 kN, suitable for medium-duty industrial applications.
- Chrome Steel GCr15: Premium bearing-grade steel hardened to HRC 58-64 ensures high hardness, wear resistance, and fatigue life under continuous operation.
- Cast Iron HT200 Housing: Robust pillow block housing absorbs vibration and provides stable mounting with self-alignment capability.
Applications
YEL209-2F pillow block bearing units are widely used in:
- Conveyor belt systems and material handling equipment
- Agricultural machinery (harvesters, tillers, balers)
- Food processing and packaging machinery
- Textile machinery and spinning equipment
- HVAC fans and blowers
- Construction and mining equipment
Why Choose our Eccentric Lock Insert Bearings
Compared to standard set-screw locked pillow block bearings, the YEL series eccentric locking design offers 3x better resistance to shaft loosening during reversing and vibration-intensive applications. The extended inner ring provides enhanced shaft support for cantilevered loads, reducing deflection and premature wear. The 2F double-seal configuration extends re-lubrication intervals and protects the bearing in harsh environments.
