SFNB production metric, inch single, double, four-row tapered roller bearings - Types
Single row tapered roller bearings
Such bearings can only limit shaft or housing in one direction of the axial displacement in
one direction to bear the axial load. In the radial load of action, the axial force generated in
the bearing must also be balanced. Two face to face or back to back bearing should be
used.
Double row tapered roller bearings
Such tapered bearings in radial load at the same time can withstand axial load. The axial
clearance in the bearing within the shaft or housing to limit axial movement of the two-way.
Four-row tapered roller bearings
Performance of such bearings and double row tapered roller bearing is basically the same,
but more than double row tapered roller bearings under radial load bigger, lower speed
limits, mainly for heavy machinery, such as rolling machines.
Four-row tapered roller bearings
SFNB provide long-life four-row tapered roller bearings. Personalize bearing the new
design, fully sealed bearing change traditional design method, using the new structure type
seal and dust seal combination, to improve the sealing effect, improve sealing
performance. Multi-sealed double, four-row tapered roller bearings compared with open
structure bearing, life expectancy increased by 20% to 40%; lubricant consumption
reduced by 80%.
