KRV16PP bolt roller bearings

Bolt: mechanical parts, with nuts cylindrical threaded fasteners. By the head and the screw ( The cylinder with external thread) Two parts of fasteners, need to cooperate with nut, used for fastening the two parts with hole. This kind of connection form according to bolt connection. Such as screw the nut on the bolt, and can make the two parts separately, so the bolt connection is a detachable connection. Product introduction roller bearing outer ring with outer wall full of thick cylindrical roller bearing, outer diameter of the wheel surface with cylindrical and curved, can design according to the use of occasions to cooperate with raceway surface. Use of the outer ring, rolling roller can be directly on the rolling path, and can withstand heavy loads and shock loads. Composite roller bearing by the main roller, side roller, shaft head and cover plate. Combination of 1, the main roller main roller of roller bearing is mainly of a composite roller bearing, mainly under the vertical load and impact load, has a strong impact resistance, abrasion resistance and corrosion resistance. The main roller for full roller bearings, can also be used as one-way bearing separately. 2, side roller side roller main carry horizontal load, and also has a strong impact resistance, abrasion resistance and corrosion resistance. Side roller for without inner ring with roller design, replace by a spindle bearing inner ring and the shaft head. 3, shaft head shaft head is as the composite roller and parts of machinery and equipment connections, usually shaft head head design for chamfering, convenient installation, can be directly to the spindle head welding on the device, also can be in shaft head welding connection plate with circular hole then the connection plate and equipment assembly. 4, is the role of flat plate installed on the shaft head inside the side roller, shaft head outside the main roller with nut and screw glue together at the end of the shaft head is an important part of. Roller bearing installation 1, bearing washed with kerosene, pressed into the bearing seat, fill toward the roller bearing outer ring shell 3 lithium base grease to two-thirds full, with clean hands evenly daub, mount NTN bearing gland, use add bolt locking glue binding bolt pressure bearing gland; 2, bearing for inside and outside the separable cylindrical roller bearings, bearing suits on the rotating shaft and should be in place; 3, the bearing seat is installed on the casing, such as a grease oil injection hole, must be on location. Use add bolt fastening bolt bearing seat tightly locking glue; 4, inside and outside the eccentric block is installed on the rotating shaft and is in place, with the shaft key shaft key should be loaded in the keyway reload eccentric block, shaft with ring on the rotating shaft; 5, tight the bolt fixed eccentric block, adjustable eccentric block, make its reach to unload in front of the Angle position and tighten the fastening bolts. Above after completion of assembly, shaft should have certain axial string move; 6 at the ends of the shield, the vibration motor, with the screw fastening. Roller bearing maintenance thin oil lubrication: advantage is that internal friction coefficient is small, so to overcome the friction consumes less energy, thin oil good liquidity, easy into all lubricating points of friction surface, has the good cooling effect, and adhesion on the friction surface impurities and can be produced by grinding metal particles away. The disadvantage is that the oil film cannot unit under big pressure, high requirement for sealing. High speed press with large flow dilute oil lubrication, more commonly can take away the heat generated by the friction pair.
