IV. Primary Uses
Suitable for medium-speed, heavier radial + unidirectional axial load scenarios, commonly found in:
🚗 Car: Wheel hub, differential, transmission
🏗️ Construction Machinery: Gear reducers, gearboxes, track rollers
🏭 Factory / Mining / Metallurgy: Crushers, Grinders, Conveyors
🛠️ Machine tools / General machinery: Spindles, sawing machines, pumps, fans
V. Characteristics
Capable of withstanding radial force + unidirectional axial force
The inner/outer ring is separable, allowing for easy installation and disassembly
Must be installed in pairs (back-to-back / face-to-face) to balance bidirectional axial forces
Low friction, long service life, suitable for medium to high-speed heavy-duty applications
