We use several special greases which are in general all formulated by combining a base oil with a thickening agent. They lubricate rolling bearings by bleeding a small amount of oil out of the “reservoir” of the grease thickener and into the raceway. The oil provides the elastohydrodynamic lubricating film needed to reduce friction and wear. Greases can also serve as effective seals to protect bearings from contaminants and moisture. For greater loads, especially where vibration or shock loading is likely, such as pivots or headsets, special anti-wear additives can improve grease performance. Likewise, special thickeners and additive packages can augment a grease’s natural resistance to wash-out by water or salt-water spray. Thickeners can also be processed to reduce the noise-generating characteristics of a grease.
For ceramic hybrid, stainless steel, Abec 5 angular contact, and Abec 5 radial bearings we use Kluber 72-72. This grease only runs better and smoother with time and is highly resistant to being washed out. It is engineered to stick to the balls and continually be pulled back into the ball path where it is needed.
For our ABEC 3 bearings we use an extra high pressure grease, Mobil XHP 222, which is an excellent and clean rolling grease and which also features great water displacement characteristics. Well suited to any and all bikes and riding conditions.
We use Almagard 3752 for ultimate high pressure characteristics. These high pressure greases will not get pushed out by the extreme loads of a suspension bearing pivot or headset bearing for example.
For MAX type bearings and some bottom bracket bearings, we fill both sides with CRC Marine grade grease for ultimate salt water protection. This grease is specially formulated to withstand the elements, including rain and snow, and is especially handy for riding on iced roads.
