Steel Bearings with Solid Lubricants are engineered for heavy-duty applications requiring high compression resistance and reliable, low-maintenance operation. Constructed from bearing steel with embedded solid lubricating particles, these bearings form a protective lubrication layer during use, minimizing friction and wear while delivering superior anti-seizure performance compared with conventional oil-lubricated monomer materials.
High-Strength Steel Base: Provides excellent load-bearing capacity and structural durability.
Embedded Solid Lubricants: Releases lubrication particles during operation, forming a protective film between the shaft and bushing.
Anti-Seizure Performance: Outperforms traditional oil-lubricated bearings under heavy loads and harsh conditions.
Low Maintenance: Self-lubricating properties reduce downtime and extend service life.
Lifting machinery supports and hoister systems
Crane bearing and pivot supports
