BARRIERTA

BARRIERTA

BARRIERTA L 55/2 for rollers in waffle baking machines.
The grease is still in good condition after 3,000 hrs.

Temperature plays an important role in the lubrication of rolling bearings. Previously, extremely high temperaturescould be mastered only by way of correspondingdesignmeasures oil circulationubrication.Now,BARRIERTA lubricants specially developed for temperatures from200 to 260 °G close thisclassic gap. And
new possibilities have now been providedfor long term and lifetime lubrication in the100 to 200 °G range.While mineral oil base lithium soapgreases retain their lubricity fo maximumof 200 hrs at 150 °q, andsilicone greasespolymerizeto a rubberymass at 200 °G, BARRIERTAlubricating greases are not subject to carbon formation or polymerization even at260 °G. Those with the biggest thermalstability exhibit a change in penetration ofonly some 50 x 0.1 mm after 1,000 hrsat 250 °G.
Subjected to mechanical anddynamic stresses in ball bearings,lubricating intervals exceeding 1,000 hrsare possible.
Due to their exceptional thermal stability,BARRIERTAlubricants are valued ashigh-temperature structural elements forrolling bearings.

250 °G

Fr = 5,000 N

lubricating intervals exceeding 1,000 hrsare possible.
Due to their exceptional thermal stability,BARRIERTA lubricants are valued ashigh-temperature structural elements forrolling bearings.
Some examples:
:: load and turn rollers in conveyors,automatic bakery ovens and drying kilns
:: Running wheels on oven andautoclave carts
:: Guide rollers in fabric conveyor chains in stentors
:: Rolling bearing assemblies incalendars or coating plants
:: Bearing assemblies in electricmotors and fans.
