Applications that demand high running speeds, easy handling and long service life will benefit from NSK<\/a><\/strong>\u00b4s new four-point contact ball bearings. The QJ series features a high-strength outer-ring-guided brass cage to facilitate extremely high speeds and improved running accuracy.\u00a0<\/p>\n\n\n\n

Furthermore, a 35\u00b0 contact angle helps to provide longer operating life thanks to the resulting high axial load capacity, which in turn minimises the costs associated with downtime and maintenance. Among many notable features, QJ series four-point contact ball bearings comprise an inner ring that splits into halves. Users can separate the outer ring of these advanced single-row angular contact ball bearings from the halves of the inner ring (split along a plane perpendicular to the shaft centre), to promote easy handling.<\/p>\n\n\n\n

To meet the challenges of demanding applications, NSK QJ bearings are also able to sustain significant axial loads in both directions. As a result, the bearings are ideal for carrying pure axial loads, or combined loads where the axial load is high.<\/p>\n\n\n\n

Another major advantage is the compact size of the QJ series. A single QJ unit can replace a face-to-face or back-to-back arrangement of conventional bearings, saving valuable design space.<\/p>\n\n\n\n

Among a myriad of applications set to benefit are oil-free screw compressors, industrial pumps, tractor transmissions, robot gearboxes and servomotors. Further applications in the petrochemical, chemical and pharmaceutical industries can also take advantage of the added value these bearings provide.<\/p>\n\n\n\n

The added value stems from many factors, not least the decades of experience and expertise that NSK applied in the creation of a special internal design complemented by a precision-machined brass cage. This combination delivers increased limiting speed, high dimensional and running accuracy (P6), and a narrow axial clearance range. Additional advantages include reduced heat generation, vibration and noise.<\/p>\n","protected":false},"excerpt":{"rendered":"
