5 SK Cartrige Spinles SK Cartrige Spinles s an eatures High-rigiity G series (G-40V, G-50V) or achining Centers High-rigiity G series (G-40V G-45V, G-50V) High raial rigiity is achieve with a ouble-row cylinrical roller bearing incorporate in the fixe sie. The application of a high-spee angular contact ball bearing with a contact angle of 30 for thrust loa provies axial rigiity with high-spee operation. The ouble-row cylinrical roller bearing integrate in the free sie provies a large loa capacity an ensures smooth axial movement against shaft elongation cause by rising temperatures. High-spee H series (H-30V, H-40V) high-spee angular contact ball bearing with a contact angle of 15 is integrate in the fixe sie. lthough mainly use for high-spee operation, these bearings are also applicable to normal cutting at meium or low spees since their quaruple configuration maintains rigiity. The free sie incorporates a ouble-row cylinrical roller bearing, as in the high-rigiity series. Economy type (E-40) s a stanar stock prouct, elivery is swift. Spinle functions require for cutting work are integrate in a compact boy available at an unpreceente price. The high level of precision is suitable for a wie variety of fiels, incluing automobiles, electrical appliances, machine tools, optical instruments, an metals. urthermore, the cartrige bracket can be easily attache an etache. Tool clamps are built into the shaft, facilitating easy tool replacement. V-types are use for vertical installation, while H-types with rain holes are available for horizontal installation. uilt-in tool clamps facilitate easier operation (suitable for TC). Use S T as the tool holer. Use S I as the pull stu. The outer casing is provie with a coolant groove. When cooling, ajust the coolant oil temperature to room temperature. (low is approximately 5 /min) Insert an O ring between the unit an bracket before cooling the outer casing. General purpose tool holers (T #40, pull stu S I) can be use. The air seal cover type an V pulley are optionally available. * The air seal cover itself is not sol separately. The V pulley is an optional item sol separately; contact SK for preinstalling a V pulley in the unit. Contact SK for special proucts with custom-tailore specifications, such as high-spee rotating types an shaften moifie types. Economy type (E-40) or C athes High-rigiity series (-5, -6) Same bearing arrangement as the G series for machining centers. High raial rigiity is achieve with a ouble-row cylinrical roller bearing incorporate in the fixe sie. high-spee angular contact ball bearing with a contact angle of 30 for thrust loa provies axial rigiity along with high-spee operation. The ouble-row cylinrical roller bearing integrate in the free sie provies a large loa capacity an ensures smooth axial movement against shaft elongation cause by rising temperatures. The shape of the shaft en on the mounting part conforms to JIS V-pulley, synchronize pulley, parallel key, an rive button shoul be furnishe by the customer. Runout accuracy: ll types in this series feature mounting raial an axial runouts of 2 μm or less. ll types in this series are use for horizontal installation an provie with rain holes.

The preloa of the tapere roller bearings is ajuste by rotating the roun nut mounte on the rear of the spinle. The angular contact ball bearing is spring preloae, thus the main spinle shaft is supporte at 3 points.
