Manufacturers of high-temperature ball bearing greases have a new go-to base oil – IOTA BJ550 Polyphenylmethyldimethylsiloxane. This advanced lubricant offers low volatility and a flat viscosity temperature curve, ensuring consistent performance across a wide temperature range. Its low viscosity of 125mm²/sec at 25°C further enhances its efficiency.
