Beli bearing alternator di monotaro.id

Drawn Cup Needle Roller Bearings. This bearing type is composed of an outer ring drawn from a thin steel plate by precision drawing, needle rollers and a cage assembled in the outer ring after the raceway surface thereof was hardened (A bearing marked with a suffix including M is subjected to heat-treatment after assembly). Of the bearings with outer ring, this bearing type is a bearing with the smallest section height which enables space-saving and cost-saving. Usually design is so made as to use a shaft as the direct raceway surface without using inner ring. The outer ring of this bearing type is of such a construction that the needle rollers and the cage are not separated from one another, so that the bearing is only press-fitted in a rigid housing with proper fit torque. Thus, this bearing type needs no snap ring, etc. to fix itself in axial direction and, in addition, is easy to handle.

STC series alternator are to be used in town, the countryside, Worksites, mountain districts and pasture lands as a electric power source for lighting purpose, It can also be used as a reserved power source for emergent case. The generators are of drip-proof with rotary field type and with the adoption of harmonic excitation system, that allow your easy operation and simple maintenance. The generators are of three-phase four-wire type. Making use of star connection with neutral point. The rated line voltage is 400V.phase voltage 230V.frequency 50Hz,power factor 0.8(lag).It can provide 60Hz and the other voltage's generator according to necessary.

The ST series generators are mainly designed to serve as power generating unit of small capacity which supply electricity for lighting purpose in ships as well as for household electric devices used in towns or villages.
