Dynamically light, long-term lubricating grease

  • ISOFLEX LDS 18 SPECIAL A is a dynamically light long-term grease for plain and rolling bearings. It consists of ester oil, mineral oil and lithium soap. The product is resistant to ageing, oxidation and water, and it protects reliably against corrosion
  • Content: Can 1 kg
  • Available in Tube 45 g, Cartridge 400 g, Can 1 kg, Bucket 25 kg

Benefits for your application

  • Long service life due to good corrosion protection as well as ageing and oxidation stability, hence cost savings
  • Tried-and-tested for many years, especially at high speeds and low temperatures
  • Low heating-up of bearings due to low lubricant friction leading to longer service lives


  • ISOFLEX LDS 18 SPECIAL A is suitable for plain and rolling bearings operating at low temperatures and/or high speeds, for example in grinding spindles, machine tool spindles, spindle bearings, textile spindles, bearings in OE-spinning turbines, bearings in precision and optical equipment
