CRBT Crossed Roller Bearing are extremely compact bearings having cylindrical rollers disposed perpendicularly between inner and outer rings.A single bearing can take complicated loads such as radial, axial and moment loads.By using cylindrical rollers whose elastic displacement due to load is smaller than steel balls, this type of crossed roller bearing can make the device compact and highly rigid.
Features:
1.Advanced equipment and measuring instruments
2.Skilled production assembler
3. Good contour tolerance and runout accuracy.
