Tell us the designation — NU, NJ, N, NUP or NF — and we will confirm stock from 20 mm to 320 mm bore. The letter matters more than most buyers realise: NU and N float axially, NJ and NF locate the shaft one way, NUP locates it both. Get it wrong and the shaft either binds or wanders. Cylindrical rollers sit on the raceway along a line rather than a point, which is why they carry far more radial load than a ball bearing of the same size.
A cylindrical roller bearing carries load through rollers that contact the raceway along a line rather than at a point. That line contact spreads the load over a far larger area than a ball can, which is why a cylindrical roller bearing of a given size carries substantially more radial load than the equivalent ball bearing.
The trade-off is axial capacity - because the rollers run between flanged and unflanged rings, most types carry little or no thrust. NU and N types float axially, while NJ, NUP and NF types locate the shaft in one or both directions.
The design is also separable, meaning the inner and outer rings mount independently - a real advantage in gearboxes and motors where both rings need an interference fit. As a cylindrical roller bearing stockist in India, we supply matched sets across all five series for exactly this kind of application.
Pragati Enterprises is a trusted cylindrical roller bearing supplier in Mumbai, offering genuine NU, NJ, N, NUP and NF series bearings for gearbox shafts and electric motor applications. As a cylindrical roller bearing distributor and stockist, we hold bore sizes from 20mm to 320mm in stock, with fast dispatch across Mumbai, Pune and PAN India.
Flange configurations and series we hold and source for Indian industry.
Two integral flanges on the inner ring, none on the outer. Rings float axially, so the bearing acts as a pure non-locating radial support that accommodates shaft expansion.
Two flanges on the outer ring and one on the inner, locating the shaft axially in one direction while carrying heavy radial load.
Two flanges on the outer ring, none on the inner — the mirror image of NU, used where the inner ring must move freely with thermal expansion.
Two integral flanges on the inner ring plus a loose flange washer, giving axial location in both directions. The standard choice for a locating bearing position — where full axial thrust support is needed, this is paired with a thrust bearing at a dedicated locating point.
One flange on the outer ring, two on the inner — one-direction axial location in the reverse sense to NJ.
Two rows of rollers in a single unit for very high radial capacity and running accuracy in a compact width. As a cylindrical roller bearing distributor supplying machine tool and rolling mill customers, this is our most requested design for spindle and roll-neck positions.
