FAG Angular Contact Ball Bearings
Product Description
The QJ318-N2-MPA FAG four-point contact ball bearing consists of a solid outer ring with two retaining slots, a split inner ring, balls, and an outer-ring-guided solid brass cage. The four-point contact design provides high axial load capacity in both directions while also supporting limited radial loads. The N2 retaining slots provide secure outer-ring location, while the robust MPA brass cage provides reliable ball guidance and stable operation under demanding conditions.
The QJ318-N2-MPA bearing is widely used in railway gear units, heavy industrial gearboxes, large reducers, and heavy-duty drive systems. It is particularly suitable for applications requiring high bidirectional axial load capacity, secure outer-ring location, robust cage performance, and stable operation under heavy-duty conditions.
