NLGI currently licenses grease through their Certification Mark program which includes the well-known GC-LB Performance Classification. This certification program has provided an internationally-recognized grease specification for grease and bearing manufacturers, users and consumers since 1989. Although originally conceived as an automotive chassis and wheel bearing specification, GC-LB is recognized as a mark of quality for grease specifiers. Due to advancements in materials, technologies and applications, NLGI recognizes that current applications may be better served by updated specifications.
Because NLGI’s working groups are made up of volunteers from the industry, NLGI has contracted with The Center for Quality Assurance to interview and survey members of the grease industry with a goal of defining these new specifications and ensuring that they meet the needs of today’s grease-lubricated applications. The initial focus will be on updated specifications for a premium grease that could be used in a variety of bearings and applications which require similar lubricating properties. Additional specifications will be defined for high load, water resistance, corrosion resistance, low temperature and long-life applications. Future specification work may include grease for gear boxes, electric motors and other applications.
*Please note the GC-LB is not being replaced. The new specifications will be in parallel to GC-LB. NLGI will continue to support GC-LB certification and the use of the mark on finished products. The new specifications, certification and marks will be used in applicable applications. NLGI will continue to support the use of the current GC-LB marks as long as there is a market for them.
