Tensioner pulleys for textile machinery NTN Tensioner Pulleys for Textile Machinery These pulleys are used to guide and tension the tapes and belts driving the spindles of a fine spinning machine, a roving frame, a false twister, etc. A pulley drawn precisely from steel plate by precision deep drawing is press-fitted in the outer ring of shaft bearing in in place of inner ring. Composition of nominal number Nominal number <strong>com</strong>prises type code (JPUS) , dimension code (Pulley outer dia. (D) and tail code. Tension pulley with special-purposed holder is represented by nominal number + tail code (holder nominal number). Types and construction Single-row or double-row ball bearing is built in this pulley, which is internally prefilled with lithium soap base grease. Grease is replenished through a grease hole which is internally provided in the stud. Two different mounting methods are available as follows for these pulleys; one method is to bolt a pulley to the roller carrier of machine with holder bolt using a special-purposed holder (Type code: JFS) and another method is to bolt directly a pulley to machine frame using the bolting hole drilled in the stud and a corresponding hexagon head bolt. A knock pin press-fitted in the stud end face is to lock the bolt after tightened. When a pulley is directly bolted to machine frame, provide the hexagon head bolt center with a grease through-hole for grease replenishing and screw a grease nipple in its end face. In mounting a double-row ball bearing type tension pulley, insert the stud directly into machine frame and tighten it with nut, without using the special-purposed holder. Replenish grease using the box nut.
