NACHI spherical roller bearings–NACHI Spherical roller bearings are of an improved design having a modified line contact between the raceways and rollers. This construction enables very high radial and impact-Ioad capacity. This bearing type can carry a moderately-high level of bi-directional axial load and is self-aligning.
NACHI spherical roller bearings are used extensively for large machines where where misalignment can arise from error in mounting or from shaft deflection. Spherical roller bearings are used for paper mill equipment, rolling machines, rolling stock, shaker screens and general industrial machinery.
When using NACHI spherical roller bearings, there are something should pay attentions to:
(1) For high axial load applications, the axial load Fa must not exceed 0.6 of the radial load Fr. If the axial load exceeds 0.6 Fr, contact NACHI engineers for design assistance.
(2) For applications where oscillating loads (such as shaker screen applications) or high speed is involved, contact NACHI for design assistance.
(3) In very lightly loaded or no load conditions, sliding motion can occur which could damage the bearing. To prevent this, bearings must be subjected to a load greater than 0.02 Cr (basic dynamic load rating).
(4) The material coefficient number of the bearing is taken into consideration for the dynamic load rating.
