NN 3038 K/SPW33 Double Row Cylindrical Roller Bearing 190x290x75 Mm
The NN 3038 K/SPW33 bearing is a Cylindrical roller beairngs with an inner diameter of 190 mm , an outer diameter of 290 mm, a width of 75 mm. It typically uses P6 P5 P4 grade precision tolerances and features a Brass cage, Bearing Steel rings. It primarily bears Axial/Radial, Its dynamic radial rated load is approximately 0.6 kN, its static radial rated load is approximately 1.08 kN. It uses C1 standard radial clearance, Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Feature: 3 Rib Inner Ring, Plain Outer Ring, Cage on Inner Ring OD
Application: gearboxes, agricultural machinery, pumps, compressors, and electric motors
NN 3038 K/SPW33 Double Row Cylindrical Roller Bearing 190x290x75 mm
Cylindrical Roller Bearing, NN 3038 K/SPW33, 190x290x75 mm, Brass Cage, Double Row, No Seal, Outer Ring-Two sides Separable; No Snap Ring, Relubricatable, C1.
Super-precision double row cylindrical roller bearings in the NN 30 series provide a unique balance between load carrying capacity, rigidity and speed. Having three flanges on the inner ring and no flanges on the outer ring, the bearings can accommodate axial displacement in both directions. The separable design simplifies mounting and dismounting, particularly when load conditions require both rings to have an interference fit.
K: Tapered bore, taper 1:12
SP: Special Precision Class For Machine Tool Bearings: Dimensional Accuracy Approximately To P5, Running Accuracy Approximately To P4.
W33: Lubrication Groove And Three Holes In Bearing Outer Ring.
