Heavy-Duty Grease Performs in Extreme Conditions

Almaplex Ultra-Syn Lubricant has the power to increase equipment uptime and enhance bottom line profitability by offering exceptional quality, versatility and reliability. A heavy-duty synthetic grease containing LE’s proprietary additives Almasol® and Quinplex®, Almaplex Ultra-Syn provides optimum performance under extreme operating conditions. It is an aluminum complex thickened grease made with an ISO 460 viscosity synthetic base fluid, a combination that provides superior high-temperature functionality, low-temperature pumpability and excellent performance in the presence of water.

Almaplex 1299 & 1298 (NLGI grades 2 & 1, respectively) provide 73 percent higher extreme pressure performance than competitive grease, as indicated by the results of the Four Ball EP Test. In the Water Spray-Off Test, competitive greases lost almost six times more grease. This performance offers the potential for energy savings and reduced operating temps in applications such as construction, agriculture, mining, steel mills and paper mills; hammer mills; extruders and ball mills. Almaplex 1299 can be used in couplings where AGMA CG-1, CG-2 and CG-3 lubricants are recommended.

Almaplex 1297 & 1295 (NLGI grades 0 & 000, respectively) are semifluid greases with superior film strength. They are excellent for use in heavily loaded bearings in cold temperature applications. They also perform well in any gearbox that requires a semifluid grease, particularly enclosed gearboxes where housings and seals have lost their ability to retain conventional gear oils.

Proprietary Additives

N/A LE’s proprietary additives are used exclusively in LE lubricants. Almaplex Ultra-Syn Lubricant contains Almasol and Quinplex.

Almasol® solid wear-reducing additive is able to withstand extremely heavy loads, chemical attack and temperatures up to 1,900°F (1,038°C). It is attracted to metal surfaces, forming a microscopic layer but not building on itself or affecting clearances. Almasol minimizes metal-to-metal contact and the resulting friction, heat and wear.

Quinplex® impact-resistant additive contributes to outstanding water resistance, tackiness and enhanced mechanical stability, and helps to form a barrier against corrosion.

Typical Applications

  • Ball mill and kiln pinion support bearings
  • Construction, agricultural and mining equipment
  • Couplings (1299 only)
  • Extruders
  • Filter presses, dewatering presses
  • Hammer mills
  • Paper mill wet end, press rolls, felt rolls andcalendar stack bearings
  • Steel mill hot and heavily loaded bearings
