Notes about B....LNMSS Series :
RBC's DuraLube™ self-lubricating spherical plain bearings are built for long-lasting performance in tough environments. They operate without grease, using a robust PTFE liner system that minimizes friction between the inner and outer spherical surfaces. These bearings are perfect for situations where re-lubrication isn't feasible but extended service life is essential. They are available in both inch and metric sizes.
Other salient points to be noted :
• Ultimate static and impact loads should not exceed 150% of catalog ratings.
