NBK PULLEY & FCL COUPLING

NBK the most reliable brand name

Standard V Pulley have been regarded as ones with the best and most reliable quality since 1950 when we standardized them in japan for the in dustries. Our incessant innovation for the manufacturing process, molding, pouring, machining, balancing and coating, have taken the state of art quality into reality.

NBK flexible shaft couplings (flanged type) as per JIS B 1452, are safe couplings most suited to transmit power efficiently and safely from the driver shaft to the driven shaft. Simple in construction, These couplings *JIS = Japanese Industrial Standard (almost same with I.S.O. & DIN)
