Double row tapered roller bearings are a whole, or like a single row, the inner and outer ring can be separated?
What type or use do you need to see in double rows? Some are whole, others are detachable
Double row tapered roller bearings, formerly known as bearings of a single tapered roller bearing, have been developed in recent years into double row components. General double row tapered roller bearings are made of four parts, sufficient allowance ring the factory are generally left, is to adjust the bearing clearance or pre load, and must be made by the assembly bearing themselves to the process of grinding, so most of the double row tapered roller bearing inner ring can be separated.
Cylindrical roller and raceway are line contact bearings. Load capacity, mainly bear radial load. The friction between the rolling body and the ring block is small and suitable for high speed rotation. According to the ring has no edge, can be divided into NU, NJ, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings. The bearing is a separable structure of inner ring and outer ring. Cylindrical roller bearings without inner sides of the inner ring or outer ring, whose inner and outer rings can be moved relative to the axial direction, so they can be used as free end bearings. The inner ring and the outer ring have double sides at one side, and the other side of the ring has a single block cylindrical roller bearing, which can bear the axial load in a certain direction. Generally use steel plate holder or copper alloy car body cage. But some also use polyamide forming cages.
