Flange Slewing Bearing Example: NTN LH series of self-aligning roller bearings

Self-aligning bearing applications gradually increased, especially in high-temperature environments and long life bearings. For different application environments, NTN engineers developed STJ2 steel high precision ball bearings type, in a wide temperature range from room temperature to extend the life of the temperature range of 250 ℃. This steel is LH series of self-aligning roller bearings standard materials. This bearing characteristics are as follows (compared with the SUJ2 of) a large temperature range and long life bearings, at room temperature is 3.5 times the normal life of the material at high temperature (250 ℃) under 30 times the life of ordinary materials to prevent surface damage, 7 dimensional stability under times of anti-flaking capacity, 1.4 times the capacity of anti-abrasion, 2.5 times the anti-wear capabilities, high temperature conditions, almost no change in size at 250 ℃, strengthen rupture fatigue strength at high temperatures and tight fit under the circumstances, a 2-fold increase in anti-fatigue cracking life. 2-fold increase fatigue strength ripstop, simplify storage Thin section bearings management program parts, from room temperature to 250 ℃ can use a single standard bearing type, self-aligning roller bearings will gradually turn into "LH series."
