SKF extreme temperature bearings operate at 350°C without relubrication
Gothenburg, 13 May 2013: SKF today announces the new offer of SKF extreme temperature bearings, featuring a graphite cage that lubricates the bearing up to 350°C without the need for relubrication. This offers an especially powerful solution in the metal industry, where operators can cut maintenance costs, boost reliability and improve product quality by replacing conventional grease lubricated bearings with the SKF extreme temperature bearings. The extreme temperature bearing is included in the SKF BeyondZero* portfolio.
“SKF extreme temperature bearings address the need for bearings that can perform in hot, dry environments on slow rotating machinery. Grease lubricated bearings often fail at temperatures exceeding 250°C because even special greases lose their ability to lubricate adequately above this temperature. In contrast, SKF extreme temperature bearings require no relubrication and can operate in temperatures up to 350°C, cutting the cost and maintenance demand of relubrication and offering a significant increase in bearing service life,” says CharlotteEnlund, Product Manager SKF dry lubricated bearings.
该领域的经验表明，使用石墨润滑的极端温度轴承可以显着提高高温应用中的轴承使用寿命。 例如，在用于金属板制造的冷床中，轴承使用寿命增加了三倍。 在这种应用中，这种轴承每年可以节省高达4,6千克的CO2e和1,5kg的润滑脂。 配备5000轴承的冷床每年可节省7,5吨润滑脂和23吨CO2e，与使用润滑脂润滑深沟球轴承相比，气候影响减少了82％。 这些计算基于轴承和油脂节省。
