Mining crushers, vibrating screens, and conveyor drives are subjected to shock loads, misalignment, and abrasive contaminants. The 22300 series spherical roller bearings (SRBs) offer self‑aligning capability and high radial load capacity to maximize uptime in the harshest environments.
Bore Range: 35 mm – 200 mm
Roller Rows: Two rows of barrel rollers
Materials: High‑chromium alloy steel; optional corrosion‑resistant coatings
Self‑Aligning
Spherical raceway compensates up to 1–2° misalignment.
High Shock Load Tolerance
Large rollers and robust cage for impact resistance.
Contaminant Protection
Labyrinth seals or external shields available.
Lubrication Options
Grease‑filled, oil‑lubricated, or oil‑mist ready housings.
Jaw & Cone Crushers
Vibrating Grizzlies & Screens
Bucket Wheel Drives
Dragline & Shovel Slewing Rings
