The application of self-aligning bearing is gradually increased, especially long-life bearings in high temperature environments. For different application environments, NTN's engineers developed STJ2 steel, and extend the service life in a wide temperature range from room temperature to 250 ° C temperature range. This steel is standard material for the LH series of self-aligning roller bearings. Bearing characteristics as follows (with the SUJ2 the contrast) temperature range, long-life bearings in the room temperature is 3.5 times the life of common materials at high temperature (250 °C) under 30 times the life of common materials, to prevent surface damage, times the anti-spalling capabilities, 1.4 times the anti-abrasion ability, 2.5 times the anti-wear, dimensional stability under high temperature conditions at 250 °C, almost no changes in size to strengthen the rupture fatigue strength at high temperatures and tight with the circumstances, an increase of 2 times the anti-rupture fatigue life. The ripstop fatigue strength increased by 2 times, streamline spare parts management program, from room temperature to 250 °C can be a single standard Bearing, self-aligning roller bearings will be gradually transformed into the "LH series.
