IsoHiTech Grease Selection Guide – NLGI Grades, Viscosity & Thickeners

IsoHiTech (isohitech.com) has a grease selection guide that walks through the specification decisions behind a lubrication choice: NLGI consistency grades 000 through 6, base oil viscosity from ISO VG 32 to 1500, thickener chemistry beyond plain lithium, additive and EP load packages, and how each factor interacts with pumpability in a centralized system. A matching table links the common application cases (high load pins, high temperature bearings, wet or washdown areas) to a suitable grade and a pumpability chart shows where cold-start feed rates fall off. Written for maintenance engineers who need to justify a grease change rather than accept a default.
