LUBE YS2 High-Performance Grease for Heavy-Load Applications
LUBE YS2 is a high-performance grease designed for heavy-load applications by LUBE Corporation. It is part of LUBE’s original lubricant range for centralized grease lubrication systems and is specifically recommended for ball screws and guide sections operating under high load. LUBE also states that YS2 is used as a recommended grease by component manufacturers. YS2 is an NLGI 2 grease with an official recommended operating temperature range of -20°C to 130°C. Public technical data from LUBE Europe lists a typical worked penetration of 303, a dropping point of 241°C, a lithium thickener, and a base-oil viscosity of approximately 99 mm²/s at 40°C.
