NLGI established a standard for the classification of automotive service greases. To facilitate easy identification, NLGI created an identifying symbol, the NLGI Certification Mark, which identifies acceptable greases for use as a chassis lubricant (LB) and greases that are acceptable for both chassis and wheel bearing lubrication, GC-LB.

PSC offers a full line of NLGI GC-LB approved Wheel Bearing Grease for all of your needs.
