Double Row Spherical Roller Split Bearing

PMK Double Row Spherical Roller Split Bearings combine the self-aligning and load-handling advantages of spherical roller bearings with the maintenance convenience of a split design.
Ideal for heavy-duty rotating machinery where bearing inspection or replacement is frequent and downtime must be minimised — the split design enables on-shaft installation while the spherical geometry compensates for misalignment.
Key benefits
- Handles heavy radial and axial loads with misalignment compensation.
- Split design allows easy mounting around assembled shafts.
- Reduces downtime and maintenance effort.
- High durability and load-carrying capacity in demanding conditions.
- Direct interchangeability with standard non-split spherical bearings.
Applications
- Paper and steel mills.
- Crushers, fans, and material handling equipment.
- Marine propulsion and large rotating shafts.
- Mining, cement, and energy sectors with difficult maintenance access.
