Mobilgrease HTS (5 Gal. Pail)

Mobil 100637

MobilGrease HTS is a high performance extreme pressure grease, formulated for resistance to water contamination typically found steel mills, off-highway conditions, and surface mining. It also exhibits superior corrosion resistance. Its high performance properties come from the lithium complex soap with its advanced additive system.

Product Data Sheet

Mobilgrease HTR, HTM, HTS and HTF greases are leading members of the Mobilgrease brand of products, which has gained a worldwide reputation for innovation and performance excellence. Mobilgrease HTR, HTM, HTS and HTF grease products are designed by ExxonMobil formulation technologists and backed by our worldwide technical support staff.

Mobilgrease HT products were designed specifically to meet the requirements of customers for heavy-duty products with excellent: resistance to water, high temperature and with cohesive and adhesive properties. These greases offer the following features and potential benefits:

Features Advantages and Potential Benefits
High EHL viscometrics and selected additives for excellent resistance to wear for heavily loaded components Less unexpected downtime and reduced equipment replacement costs
Excellent ability to seal bearings against water intrusion, and to maintain consistency in the presence of water Fewer bearing failures caused by water contamination with reduced maintenance and replacement costs
Exceptional corrosion resistance Very good bearing protection for reduced maintenance and operating costs
Excellent grease cohesion, adhesion and tackiness at high temperatures and in presence of water spray Better stay-put properties in tough environments and extended re-lubrication potential
Good pumpability at low to moderate temperatures Can be used in centralised grease distribution systems

Mobilgrease HTR is primarily intended to address low temperature pumpability challenges. Mobilgrease HTM provides good pumpability with additional protection against water intrusion. Where an NLGI Grade 2 grease can be used, Mobilgrease HTS provides maximum bearing lubrication performance. Mobilgrease HTF provides fire retardancy for castor and hot strip mill operations.

Mobilgrease HTR, HTM, HTS and HTF greases are designed primarily for the lubrication of bearings, gears, and cams, which require high viscosity base oil. Such heavy-duty applications include:

  • Steel mill bearings,
  • Off-highway rolling stock
  • Surface mining drag lines, excavators, drills and haul trucks
