Lubricating Assembly Pastes Klüber ALTEMP Q NB 50

Assembly paste Klüber ALTEMP Q NB 50 is designed for CNC lathe chuck jaws and precision interference fits. The paste eliminates stick-slip motion and prevents fretting corrosion. It sustains constant clamping force throughout heavy high-speed machining.

White assembly paste with barium complex thickener formulated for chucks and machine guides
Prevents fretting corrosion and tribo-oxidation during oscillating micro-movements and vibration
Preserves consistent clamping force in CNC lathe chucks during high-speed series machining
Exceptional resistance to water-miscible metalworking coolants and mineral cutting oils

Precision spindle bearing lubrication procedure using Klüber ISOFLEX NBU 15

To guarantee the calculated operating life of high-speed spindle bearings in precision CNC machining centers, Klüber ISOFLEX NBU 15 grease must be metered strictly according to bearing engineering guidelines.

Prior to initial charging, all internal bearing cavities and rolling tracks are thoroughly rinsed with volatile hydrocarbon degreasers and dried using dry compressed air.

Filling the free internal space of the bearing with the barium-thickened specialty grease is maintained between fifteen and twenty percent for speed factors exceeding one million.

Following assembly, a mandatory progressive break-in cycle with stepped rotational speed increments is performed to stabilize operating temperature and ensure optimal lubricant distribution.

Application of high-temperature Klüber BARRIERTA L 55/2 greases in thermal equipment

Specialty synthetic grease Klüber BARRIERTA L 55/2 based on perfluoropolyether base oil and PTFE thickeners is engineered for rolling components operating under continuous thermal exposure up to positive two hundred and sixty degrees.

Before the first application, the friction zone must be completely cleaned of hydrocarbon and synthetic oil residues using dedicated solvents.

The chemical immiscibility of fluorinated polyethers with conventional lithium or mineral greases demands absolute cleanliness across metal contact surfaces.

The grease is applied as an even thin coating manually or through specialized dispensing equipment, providing long-term lubrication for kiln conveyors, curing ovens, and vacuum lock mechanisms.

Charging and maintenance procedures for Klübersynth GH 6 polyglycol gear oils

Synthetic industrial gear lubricants of the Klübersynth GH 6 series formulated with polyalkylene glycol base fluids are developed to minimize friction losses across heavily loaded worm gears and helical transmissions.

Because polyglycols are chemically immiscible with mineral oils and polyalphaolefins, the gearbox sump must be thoroughly flushed prior to oil changeover.

Ongoing oil condition monitoring requires regular evaluation of acid number, viscosity at forty degrees Celsius, and dissolved moisture content.

Due to the hygroscopic nature of polyglycol fluids, transmission breathers must be fitted with desiccant silica air filters to eliminate ambient moisture ingress during plant temperature fluctuations.

Assembly of mechanical components with Klüber ALTEMP Q NB 50 paste against fretting corrosion

White assembly paste Klüber ALTEMP Q NB 50 is utilized during the fitting of automated lathe chuck jaws, splined shafts, and machine guideway assemblies.

The paste reliably prevents tribo-oxidation, fretting corrosion, and galling between matching metallic surfaces under severe contact loads and oscillating micro-displacements.

The paste is applied as a uniform thin film over degreased contact surfaces of master jaws and wedge guides using clean lint-free cloths or spatulas.

Outstanding resistance to water-miscible metalworking emulsions preserves uniform workpiece clamping forces and prevents component slippage during high-speed turning cycles.
