White Industries Bottom Bracket
WHITE INDUSTRIES TI TITANIUM B/BThe White TI bottom bracket is a jewel-like marvel of a replacement B/B. The cups are made of machined aluminum, using precision sealed bearing cartridges for the bearing structure, machined Titanium crank bolts, and a TI 6-4 Titanium spindle. The bearing cups are made from machined aluminum rod, turned and cut on a lathe, drilled from each side for the bearing and spindle, then threaded for the B/B shell. The bearing cartridge is pressed in from the outer side and nestles against an inner lip in each bearing cup. Outside the bearing cartridge is a machined aluminum locking collar, that slides down the spindle and cinches down on the spindle using three recessed allen head bolts. These 2mm allen bolts are accessible through two small holes on the flat sides of the outer flange on each bearing cup. This locking collar fits in the bearing cup flush with the outer surface of each cup. This accessibility permits you to simply and easily "float" the spindle to the position needed for your crankset. The bearing cartridges used in this B/B are Japanese SMT bearings model 6903RK. The Phantom is available in English thread, with spindle lengths of 108mm, 110mm, 112mm (XTR), 112mm (XT), 113mm, 114mm, 115mm (XTR), 115mm (XT), 117mm, 119mm, 122mm, 125mm, 128mm, 132mm, or 135mm. The White TI comes with the needed 2mm allen wrench, and has Silver anodized bearing cups and locking collars to match the Silver colored Titanium spindle. Crank bolts are not included. The weight of the White Titanium bottom bracket with a 122mm spindle is 165 grams. Made in California. Spindle Length-08-10-12-13-14-15-17-19-22-25-28-32-35/T $Price in Catalog |

In-depth Information About Metals Aluminum Aluminum is extracted electrolytically from bauxite ore. It is made by the electrolysis of aluminum oxide which is found in larger concentrations within bauxite ore. Bauxite is a mixture of the hydroxides of aluminum, together with other impurities such as oxides of iron, titanium, and silicon. Bauxite is produced by the weathering and change of aluminum silicate rocks usually found in tropical and semitropical regions where climate has produced an accelerated weathering process. Bauxite is not a rare ore and is widely available in the US, the Caribbean, and Europe. Approximately 4 pounds of read the full article... Beryllium Beryllium is a specialty metal that is steel-grey metal in color, with an extremely low density, making it very light weight. At 1.85 grams to the cubic centimeter, its density compares to that of magnesium. It is also a high strength metal, making it possible to design light weight, thin membered parts with ahigh stiffness. A column made of beryllium to support a load placed directly downward on top of it, will have a greater load carrying capacity, and be lower in weight than any other metal of equal size. Until the 1950's beryllium was used read the full article... Titanium The element titanium was discovered in 1763 by an English cleric, William Gregor who was an amateur chemist with an inquiring mind. It was in the black sands of Cornwall that he discovered the new element that had up to that time, attracted little scientific interest. A few years later, an Austrian, Klaproth, extracted the same element from an ore widely known as "rutile", which is a mineral consisting of titanium dioxide (one titanium atom, two oxygen atoms), that is a reddish-brown substance with a slight metallic luster. While rutile is the highest grade read the full article... Metallurgic Hardness Testing There are three types of tests used with accuracy by the metals industry,they are the Brinell hardness test, the Rockwell hardness test, and the Vickers hardness test. Hardness is the property of a metal which gives it the ability to resist being permanently deformed (bent, broken, or have its shape changed), when a load is applied. The greater the hardness of the metal, the greater resistance it has to deformation. Since the definitions of metallurgic ultimate strength and hardness are rather similar, it can generally be assumed read the full article... |
