SKF NU20/630ECMA — Single-row cylindrical roller bearing (NU / N / NJ / NUP)
SKF · Bearings & Power Transmission · Single-Row Cylindrical Roller Bearings
SKF NU20/630ECMA single-row cylindrical roller bearing (nu / n / nj / nup). Single-row cylindrical roller bearing. Design executions NU / N / NJ / NUP set the axial-guidance capability by rib configuration on inner and outer ring. Standard cage ECP (glass-fibre-reinforced polyamide 6.6) for bores up to 100 mm; ECM (machined brass) above. Precision to ISO 492 Class Normal / P6 / P5. Very heavy radial-load capacity at moderate speed. Suitable for reduction-gear input shafts, marine deck-machinery drives, paper-mill dryer sections. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options.
