STABURAGS NBU 30 PTM is an assembly grease containing a solid lubricant. It is resistant to water and protects against tribo-corrosion (fretting corrosion). It has proven effective in outdoor applications subject to high humidity.
STABURAGS NBU 30 PTM
- STABURAGS NBU 30 PTM is suitable as an assembly grease for applications incorporating sliding clearance fits. Applications include hot and cold water valves and taps, slideways (especially in filling machines), valve spindles and cylinder guides. The product can also be used as a sealing grease. In addition, it is suitable for the lubrication of slideways, bolts, spindles and screws, e.g. in railway bogie assemblies.
- STABURAGS NBU 30 PTM is especially suitable for external brake components of rail vehicles, such as bolts and rods.
- STABURAGS NBU 30 PTM facili-ates assembly and disassembly of ABS sensors in vehicles.
- Use the aerosol spray version of STABURAGS NBU 30 PTM for relubrication of railway brake parts where no grease nipple is incorporated. For optimum penetration into fine clearances we recommend spraying for at least 8 seconds. This will increase efficiency of brake rods in rail vehicles thus ensuring the longest maintenance intervals.
- When used for assembly and lubricating purposes we recommend the lubricant be lightly applied to the component surfaces via a lint free cloth, by hand, or by brush.
- STABURAGS NBU 30 PTM shows good adhesive strength at low temperatures down to min. -55 °C.
- Assembly grease protecting against tribo-corrosion
- Good corrosion protection
- Excellent resistance to water even under outdoor conditions
