Sealed self-aligning roller bearings are heavy-duty self-aligning bearings incorporating a sealed structure based on double-row/single-row self-aligning roller bearings. Their core comprises a spherical outer ring raceway, spherical rollers, a cage, and pre-installed seal assemblies on both sides, providing protection against contaminant ingress and grease leakage.
High load capacity
High sealing integrity
Maintenance-free
Easy installation
High temperature resistance

Product Description
The fundamental structure of sealed self-aligning roller bearings aligns with standard self-aligning roller bearings, with core distinctions lying in the sealing system and pre-lubrication design. These bearings represent heavy-duty self-aligning variants integrating sealed structures onto double-row/single-row self-aligning roller bearings. The core comprises a spherical outer ring raceway, spherical rollers, a cage, and pre-installed sealing assemblies on both sides. It automatically compensates for misalignment errors between the shaft and bearing housing while preventing contaminant ingress and grease leakage.
Product Features
- Retains self-aligning capability and heavy-duty load capacity.
- Simple installation shortens assembly cycles without requiring additional sealing components.
- Wide temperature adaptability ensures strong compatibility across diverse operating conditions.
- Long-lasting maintenance-free operation reduces equipment downtime for lubrication, lowering operational costs.
- Superior sealing protection effectively blocks contaminants such as dust and muddy water, suitable for harsh environments.
