High Performance Complement Bearing for Petroleum Machinery

Full complement cylindrical roller bearings incorporate the maximum number of rollers and rules have a low sectional height in relation to their width. This produces an extremely high load carrying capacity and permits space-saving designs to be achieved. XRB produces single and double row full complement cylindrical roller bearings as part of the standard product range
Bearing features
Single row full complement cylindrical roller bearings have solid outer and inner rings together with ribguided 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 design. Due to the kinematic conditions, however, they do not achieve the high speeds that are possible when using cylindrical roller bearings with cage. Single row full complement cylindrical roller bearings are in the form of semi-locating bearings. The bearings have solid outer and inner 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 design. Due to the kinematic conditions, however, they do not achieve the high speeds that are possible when using cylindrical roller bearings with cage. Double row full complement cylindrical roller bearings are available as non-locating, semi-locating and locating bearings. Petroleum machinery bearing supplier The bearings do not permit any skewing between the inner and outer ring.

Why XRB Full-complement cylindrical roller Bearing?
Dimensions The boundary dimensions of the full complement cylindrical roller bearings comply with DIN 616 and ISO 15 respectively. In case of the double row cylindrical roller bearing series 48 and 49 the dimension specifications according to DIN 5412-9 are met. However, NNF type bearings are excluded hereof. Operating Temperature

By standard full complement cylindrical roller bearings are suitable for operating temperatures from -30°C to +120°C. On request these bearings can be delivered heat-stabilized. Restricted by the grease and the seal material NNF bearings are suitable for operating temperatures from -20°C to +80°C.

Heat Treatment Process Rings and rollers are fully hardened by standard. On request the bearings can be offered with bainite or case hardened components. Surface By standard rings and rollers are uncoated. On request anti-corrosion or friction reduction coatings are possible.

Misalignment With single row full complement cylindrical roller bearings a maximum misalignment between the inner ring and the outer ring of 2 minutes of arc has no impact on the life time of the bearing. Double row full complement cylindrical roller bearings are not able to absorb a misalignment.

Type NCF
Bearings of this type are single rowed. They have an inner ring with two fixed flanges and an outer ring with just one fixed flange. On the flangeless side of the outer ring there is a retaining ring inserted, which keeps all bearing components together. This retaining ring serves solely for handling purposes and may not be exposed to axial load.

Due to the axial relocating ability of its outer ring this type of bearing is used e.g. to compensate length changes of shafts in consequence of thermal expansion. The maximum axial displacement value is shown in the dimension table.
