SKF LGHB2
新貨
SKF LGHB2 一條 NT.300
這一條是通用耐重耐高溫,適合用在轉速普通高溫高壓的地方
2010/09/21
這條原本是計劃用在傳動系統上的,但後來經高人指點,比較好的選擇應該是 SKF LGHP2 才對
買錯了,LGHB2 用起來也有一定水準,但考慮到價錢 C/P 值就不夠高了,不建議買
LGHB 2 | | SKF high load, high temperature, high viscosity bearing grease | | LGHB 2 is a premium quality, high viscosity, mineral oil based grease using the latest complex calcium, sulphonate soap technology. This grease contains no additives and the extreme pressure characteristics are created within the soap structure. | | | Excellent anti–oxidation and anti–corrosion properties | | Good EP performance in applications running at high loads |
| | Typical applications | | Steel on steel plain bearings | | Pulp and paper making machines | | Asphalt vibrating screens | | Continuous casting machines | | Sealed spherical roller bearings operating up to 150 °C (302 °F) | | Withstands peak temperatures of 200 °C (392 °F) | | Work roll bearings in steel industry | | Mast rollers of fork lift trucks |
