Cylindrical roller bearings of this type are double row precision bearings for machine tools. They allow radially rigid, high precision bearing arrangements and are mainly used for the radial support of main spindles.
Full complement cylindrical roller bearings have solid inner and outer rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity, high rigidity and are suitable for particularly compact designs. Due to their kinematic conditions, however, they cannot achieve the high speeds that are possible when using cylindrical roller bearings with cage.
1. Cylindrical Roller Bearings Features
1) Cylindrical roller bearings belong to separable bearings, with easy method of mounting and dismounting
2) heavy radial load, heavy shock load, high rotation speed
3) Double-row cylindrical roller bearings are greatly used for the spindles of machine tools
2. Applications:
These bearings are mostly found in middle-sized and large-sized motors, electricity generators, internal combustion engines, gas turbines, machine tool spindles, deceleration devices, unloading and lifting machines and other industrial machines.
Preparation machine, carving machine, textile machinery accessories, other unclassified, drying machine, winding and twisting machine, surgical equipment, bar code equipment, copper smelting equipment, monitoring equipment, multi-functional packaging machine, steel-making equipment, sterilization machine, smelting equipment, injection molding machine accessories, mesh belt furnace, plastic granulator, annealing furnace, knitting machine, casting equipment, etc
