3. Key Advantages
- Superior ultra-heavy radial & axial load capacity for large farm machinery and mining heavy conveying equipment
- 1:12 taper bore cooperates with H2315 sleeve to produce even clamping force for rigid shaft locking
- Spherical outer ring self-aligns automatically to absorb shaft deflection and housing assembly misalignment
- Dual 2F reinforced multi-lip sealing structure effectively blocks mineral dust, crop residues, mud and splashing wastewater
- Thickened high-rigidity steel cage maintains stable structure under long-term continuous heavy vibration and impact shocks
- Grease nipple design allows convenient on-site refueling to extend overall bearing service life significantly
- Custom options available: C3 internal clearance, open seal version, extra heavy mud resistant reinforced sealing
Cut down frequent maintenance expenses and ensure long-term stable operation of heavy-duty equipment under harsh working conditions
