Cylindrical Roller Bearings
Features:
a、Lower speed than the ball bearing with the same dimension
b、High precision
c、Low noise and small vibration
d、Mainly withstand radial load
e、Can withstang a litter axial load if outer ring and inner ring have ribs
Double row cylindrical roller bearings full performance characteristics
GainwaySL04 series double row full complement cylindrical roller bearing mainly used to sheave, as it has large radius load capacity and shock-proof ability as well as axial load capacity in both directions.
Comprising one outer ring and two inner rings, the bearing is assembled as a unit by an internal locking structure. The width of the outer ring is less than total width of two inner rings by 1 mm, two snap rings are fitted on the outer ring, oil grooves and holes are made at contact face of two inner rings, therefore the bearing application design is simplified. On both sides of the bearing mounted are steel seals, or optional rubber seal or nylon seals. All outside surfaces of the bearing components are phosphate to ensure the bearing able to work in the open air.
Application
Electric motors, machine tools, construction machineries, light industry machineries, paper machineries, textile machineries, etc.
