POLYLUB GLY

Special synthetic lubricating greases for a wide application range.

The product series POLYLUB GLY 151, 501, 801 is based on a synthetic hydrocarbon oil, mineral oil and special lithium soap. It comprises three lubricating greases reducing friction and wear in plain bearings, slideways and small gears made of plastic.

The lubrication of plastics is special in a number of ways. As the behaviour of metals and plastics differs in many aspects, the lubricants' properties have to be adjusted to the plastic. Compared to many metals, plastics are relatively soft. Solid lubricants, which may achieve a positive effect on many metal friction points, can have a negative or no effect at all on plastic lube points. With the formulation of POLYLUB GLY 151, 501, 801, Klüber Lubrication offers products which are free of solid lubricants, and offer good adhesion.

Vehicles

Gearshift linkages, moving parts of the heating and ventilation system, shock absorber seals, tie rod elements, seat mechanisms, sun roof guides, pedals.

Plain bearings

Many types of plain bearing designs. POLYLUB GLY 151, 501, 801 prevent stick-slip to a large extent, particularly in applications where normally a hydrodynamic lubricating film cannot form.

Gears

Small electric gears with plastic-metal friction components, manual gears operating at very low sliding speeds.

Pneumatic installations

Pneumatic valves and cylinders with and without piston rod (for these applications, the upper service temperature should not exceed 130 °C).

Seals

Lubricating and sealing grease for various types of seals. The POLYLUB GLY 151, 501 and 801 lubricants are also suitable for many other plastic components subject to wear caused by relative movement against metal or plastic surfaces. Owing to good damping properties, especially of POLYLUB GLY 801 and 501, noise is considerably reduced.

For many applications in connection with various plastics and elastomers
Approved by many renowned manufacturers and suppliers in the automotive industry, e.g. DBL 6827.60, VW TL 52147, Brose Fettgruppe 11 and many more
The integrated UV indicator allows a reliable lubricant detection (wave length 366 nm) even with minimum quantity lubrication
Contributes to mechanical damping and noise reduction of switches and contacts.
