AMCI 1242 Lithium 12-Hydroxy Stearate Grease – High-Performance Industrial Lubricant | AMCI Series
Engineering Background
Lithium 12-hydroxy stearate (12-HSA) thickened greases represent the global standard for general-purpose and heavy-duty industrial lubrication. The AMCI 1242 is formulated with a refined mineral base oil and a high-purity lithium 12-hydroxystearate thickener system, delivering consistent mechanical stability across a broad operating temperature range. This chemistry has been the backbone of bearing, gear, and chassis lubrication in manufacturing, mining, and process industries for decades.
Product Positioning
The AMCI 1242 is engineered for procurement engineers and maintenance teams who require a reliable, specification-grade grease for high-load, moderate-to-high temperature applications. With a net weight of 2.6 kg per unit, it is suited for both bench-top repacking and centralized lubrication system refills. Sourced and verified through Konmask.com’s industrial supply chain, this product is available for direct B2B procurement with full traceability.

Engineering Advantages
- Broad Compatibility: Compatible with most mineral-oil-based greases; lithium soap thickener is universally accepted across OEM specifications.
- Mechanical Stability: Resists shear degradation under high-speed and oscillating load conditions (ASTM D1831).
- Water Washout Resistance: Maintains film integrity in wet or humid environments, reducing relubrication frequency.
- Pumpability: Suitable for centralized lubrication systems at ambient temperatures above 0 °C.
- Rust & Corrosion Inhibition: Protects ferrous and non-ferrous surfaces in storage and operation.
- Cost-Effective: 2.6 kg bulk packaging reduces per-unit cost for high-consumption maintenance programs.
System Architecture & Signal Flow
In a centralized lubrication architecture, AMCI 1242 is loaded into the reservoir of a progressive or single-line distributor system. The pump (pneumatic, electric, or manual) pressurizes the grease through primary and secondary distribution lines to metering injectors or progressive divider valves, which deliver precise micro-doses to each lubrication point (bearing housing, pin joint, or guide rail). Relubrication intervals are set by a PLC-controlled timer or cycle counter, ensuring consistent film replenishment without over- or under-lubrication. For manual application, a standard grease gun with a hydraulic coupler (NPT or BSP) is used directly at the grease nipple (Zerk/DIN 71412).

Technical FAQ
Q: Is AMCI 1242 compatible with polyurea or calcium complex greases already in my bearings?
A: Lithium 12-HSA greases are generally incompatible with polyurea and calcium complex thickeners. A full purge of the bearing housing is recommended before switching to AMCI 1242 to prevent thickener incompatibility and softening.
Q: Can AMCI 1242 be used in food-processing equipment?
A: No. AMCI 1242 is not NSF H1 certified and is not approved for incidental food contact. Use an NSF H1-rated food-grade grease for food-processing applications.
Q: What is the maximum continuous operating temperature?
A: The recommended continuous operating temperature ceiling is +120 °C. Short-duration excursions up to +130 °C are tolerable, but sustained operation above the dropping point (≥180 °C) will cause thickener breakdown and loss of lubrication.
Q: Is this product available in larger bulk quantities (e.g., 18 kg pails or 180 kg drums)?
A: Yes. Contact Konmask.com for bulk pricing on pail and drum quantities. Lead times may vary based on stock availability.
Q: What NLGI grade is AMCI 1242?
A: AMCI 1242 is an NLGI #2 grade grease, the most widely specified grade for general bearing and chassis lubrication per OEM and ISO standards.
