The N1960K.M1.SP Ultra-precision cylindrical roller bearings are widely used in fields with stringent requirements for radial stiffness and rotational accuracy, such as: machine tool spindles (radial support for lathe and grinding machine spindles), high-speed electric spindles, rolling mills (precision rolls), industrial robot joints, precision measuring equipment, and high-precision rotating mechanisms in aerospace.

The N1960K.M1.SP bearing is a Cylindrical roller bearing, single row, separable, with cage with an inner diameter of 300 mm , an outer diameter of 420 mm, a width of 56 mm. It typically uses SP = Super Precision grade precision tolerances and bearing steel rings, bearing steel rolling mlement. Its dynamic radial rated load is approximately 609992 N, its static radial rated load is approximately 1059995 N. It uses C1 standard radial clearance, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The N1960K.M1.SP Ultra-precision cylindrical roller bearings are primarily composed of high-precision inner and outer rings (made of precision-ground bearing steel), cylindrical rollers (graded to P4 or higher precision), and a cage (solid brass or outer ring guided type). Common structures include the N10 series (double-flange outer ring, no flange inner ring) and the NN30 series (double-row structure), with the rollers and raceways employing a logarithmic curve profile design.

Ultra-precision cylindrical roller bearings exhibit extremely high radial stiffness, making them suitable for precision spindles requiring heavy loads and high rigidity. They offer high limiting speeds, and optimized roller end face and flange contact reduce friction and heat generation. Precision grades can reach P4 to P2, providing smooth rotation and low vibration. They can be used as floating end bearings to compensate for thermal expansion and maintain high positioning accuracy.
