JRZC BS2 series spherical roller bearings are engineered for heavy-duty applications with high load capacity and excellent self-aligning performance. Made from high-purity vacuum-degassed bearing steel, they ensure superior durability and fatigue resistance. The rings and rollers undergo Aichelin salt bath heat treatment for stable quality, with hardness differences less than 1 HRC—30% stricter than GB/T 34891-2017 standards. Widely used in mining, crushing, and vibrating equipment.
2RS double seals provide strong protection against dust, moisture, and slurry.
VT143 high-temperature grease ensures long-lasting lubrication under vibration.
Reinforced steel and heat treatment improve fatigue resistance.
Optimized internal geometry provides smooth, low-friction operation.
