Product Introduction
The 23948CA/W33 is a large-bore, high-capacity spherical roller bearing designed for demanding industrial machinery operating under severe radial loads and heavy shaft deflections. Featuring a 240 mm inner bore, 320 mm outer diameter, and a 60 mm total width, this model incorporates a heavy-duty "CA" machined brass cage and a "W33" annular lubrication groove with three lube holes on the outer ring. Heat-treated to deliver superior fatigue resistance, the 23948CA/W33 provides self-aligning capability to handle structural misalignment in heavy industrial drive systems, steel mills, and mining crushers.
Applications
Steel mill roll stands, continuous casters, and heavy forging equipment.
Mining machinery, jaw crushers, vibratory screens, and ball mills.
Industrial speed reducers, heavy gearboxes, and paper mill machinery.
FAQ
Q: What does the "CA/W33" suffix stand for?
A: "CA" indicates a one-piece double-pronged machined brass cage with retaining flanges; "W33" indicates an annular lubrication groove with three lube holes in the outer ring.
Q: How is this heavy industrial bearing protected for ocean freight?
A: Given its 240x320x60mm frame size, each bearing is thoroughly greased, sealed in heavy VCI anti-rust barrier film, and bolted inside an individual reinforced wooden case.
