Klubersynth LEG 4 75 W 90

Manufacturer: KLÜBER LUBRICATION (Germany)
Fully synthetic high-performance gear oil with excellent low-temperature characteristics
Klubersynth LEG 4 75 W 90 is a fully synthetic high-performance gear oil based on polyalphaolefin (PAO). It was developed for application in rail vehicle gearboxes operating under high loads - especially at low temperatures.
Because of the new base oil technology used, Klubersynth LEG 4 75 W 90 offers excellent low-temperature characteristics. This becomes evident by a much less pronounced increase in viscosity when the product is cooled down than with conventional synthetic gear oils. This enables trains to be set in motion smoothly even at very low temperature.

Benefits for your application
  • Excellent low-temperature characteristics due to the very low pour point (≤-60°C)
  • Maximum protection against scuffing: API GL-5
  • Excellent wear protection for gear teeth and rolling bearings
  • Good shear stability for reliable lubricant film formation
  • High micropitting resistance
  • Excellent ageing and oxidation stability enabling long oil change intervals
  • Wide service temperature range due to good viscosity-temperature behaviour
  • Good anti-foaming characteristics
  • Complements Klübersynth GE 4 75 W 90 especially for the low-temperature range

Polylub WH 2

Mã SP:
Multi-purpose grease
POLYLUB WH 2 is a multifunctional lubricating grease based on mineral oil and a lithium soap thickener.
The grease offers good adhesion, excellent low-temperature properties and good corrosion protection.
Special low-temperature greases
ISOFLEX TOPAS L 32 and L 32 N have been designed for extremely low temperatures. These greases consist of a synthetic hydrocarbon oil and a special lithium soap. ISOFLEX TOPAS L 32 and L 32 N are resistant to ageing and oxidation and provide good corrosion protection as well as water resistance.
ISOFLEX TOPAS L 32 N also contains a UV indicator, which ensures quality checking even with minimum quantity lubrication.
Low-noise rolling bearing grease for long-term lubrication
Kluberquiet BQ 72-72 is made up of an ester oil, a polyurea thickener and special additives. These components have been combined such that Kluberquiet BQ 72-72 offers many advantages for the lubrication of rolling bearings.

Low-temperature lubricating grease for high-speed, low-noise rolling bearings
ASONIC GLY 32 is a synthetic low-noise lubricating grease manu­factured in a clean environment.
The product components used and the grease’s low base-oil viscosity yield a very high speed factor and a low frictional torque, as can be seen from the results of measurements made on the low-temperature test rig.
Low-temperature greases for slides and small gears
Kluberlub LM 41-32 N and Kluberlub LM 41-102 are special greases based on mineral oil and a lithium soap thickener. Due to their low base oil viscosity Kluberlub LM 41-32 N and Kluberlub LM 41-102 are suitable for temperatures down to –40°C.
