High Temperature Grease with WS2 for Industrial Bearings

High Temp Grease · High Temp Bearing Grease · MK-WS2-HT EP Grease

MK-WS2-HT is a high temperature bearing grease for industrial bearings and lubrication points exposed to elevated temperature, high load, impact load, moisture or high shear. It is made with high-viscosity synthetic base oil, tungsten disulfide (WS2) particles and special additives.

Lowerfriction supplies MK-WS2-HT high temp grease in NLGI grades 0, 1 and 2 and in cartridge, jar, pail and drum packaging. The product brochure reports a dropping point above 320 °C, low oil separation, low evaporation loss and resistance to water, rust and humid environments.

Product availability: NLGI grades 0, 1 and 2 are included in the brochure, with packaging from a 400 g cartridge to a 170 kg drum. Verify the current grade, stock, packing, pricing and product documents before purchase.

Performance note: The brochure lists a temperature range of -20 °C (-4 °F) to 800 °C (1472 °F). Confirm suitability for continuous or intermittent service in the actual equipment. The 300,000 psi figure applies to WS2 as a material and is not a certified load rating for the finished grease.

Industrial applications of high temp bearing grease

Application / requirement	How MK-WS2-HT is used	Selection note
Industrial bearings	For elevated temperature, load and friction.	Confirm grade and equipment requirements.
High or impact loads	EP and abrasion resistance support severe-duty contact.	Validate load and relubrication interval.
Water or humidity	Water, rust and humidity resistance supports exposed lubrication points.	Review washout and maintenance frequency.
High shear	Mechanical stability supports repeated shear conditions.	Confirm consistency and compatibility.

Choosing an NLGI grade

The brochure gives NLGI 0 at 310–340, NLGI 1 at 259–265 and NLGI 2 at 220–250 penetration (0.1 mm). Select the grade based on the equipment specification, lubrication system and application technique, not on the temperature claim alone.
