Part number: N307 Inside diameter: 35mm Outside diameter:80mm With:21mm Cage type: plastic Seals or shields: open Clearance:standard Dynamic load rating: 75KN Static load rating:63KN Fatigue load rating: 8.15KG Reference speed rating:9500R/Min Limiting speed rating: 11000R/Min The N307 FAG is a single-row cylindrical roller bearing with cage. This bearing consists of a solid inner and outer ring with cylindrical rollers in a cage. This cage prevents contact between the cylinder rollers, so this bearing type can support higher speeds than full-complement cylinder roller bearings. Also, single-row cylindrical roller bearings with cages are very rigid and they can take high radial forces. As the inner and outer rings of these bearings can be easily disassembled, they are very easy to install. Applications of single-row cylindrical roller bearings include gearboxes, agricultural machinery, pumps, compressors, and electric motors. The N307 FAG is a single-row cylinder bearing with N design. The inner ring has two rigid ribs, while the outer ring has none. As a result, N bearings are only capable of supporting radial forces. This bearing type is commonly used as a floating bearing. Floating bearings allow axial displacement of the shaft relative to the housing in both directions. This is necessary in applications where the shaft material shrinks or expands due to temperature changes (thermal expansion).
