Frequently Asked Questions
Q: What is the GR-9020 multi-purpose grease and what equipment does it service?
A: The GR-9020 is a lithium-based multi-purpose grease designed for electric lift trucks, pallet jacks, and material handling equipment. It lubricates bearings, pivot points, steering mechanisms, and lift chains in electric pallet jacks, forklifts, and hand trucks from brands like Crown, Toyota, Raymond, Hyster, and Jungheinrich.
Q: What are the specifications and properties of the GR-9020 lithium grease?
A: The GR-9020 is a National Lubricating Grease Institute Grade 2 lithium soap thickened mineral oil grease. It has an operating temperature range of minus 15 degrees Celsius to 130 degrees Celsius. The grease exhibits good water resistance, rust protection, and mechanical stability suitable for electric lift truck bearing and chain applications.
Q: How often should the GR-9020 be reapplied to electric lift truck bearings?
A: For daily-use electric lift trucks, reapply GR-9020 grease to load wheel bearings every 3 to 6 months or every 500 operating hours, whichever comes first. High-humidity or wet environments require more frequent application. Inspect bearing condition and listen for noise or grinding sounds between service intervals.
Q: Is the GR-9020 compatible with existing grease in electric lift truck bearings?
A: The GR-9020 lithium grease is compatible with most standard mineral oil-based greases used in material handling equipment. However, do not mix synthetic greases with mineral-based GR-9020. Always clean bearing cavities of old grease before applying fresh GR-9020 for optimal performance.
Q: What is the shelf life and storage requirement for the GR-9020?
A: The GR-9020 grease has a shelf life of approximately 24 months when stored in original sealed containers at room temperature in a dry location. Exposure to extreme heat, direct sunlight, or moisture will degrade the grease properties. Store in covered warehouses away from temperature extremes.
Q: What equipment bearing points require GR-9020 grease on electric lift trucks?
A: Primary grease points on electric lift trucks include load wheel and steer wheel bearings, mast pivot bearings, tilt cylinder pins, control linkage pivot points, and lift chain gudgeons. Consult your specific lift truck service manual for complete lubrication point mapping and grease quantities required per application.
