Cylindrical Roller Bearings NU2xx & NU3xx Series
NU Series are non-locating, single row Cylindrical Roller Bearings with cage. The inner ring is separable and without flanges on their side of the roller which slides in both directions and is commonly found in motors.
To meet the various needs, cages are made from three different materials:Polyamide(ECP),Steel(ECJ), Brass(ECM).
Cylindrical Roller Bearings NJ Series
Single row cylindrical roller bearings are designed to accommodate high radial loads in combination with high speeds. Having two integral flanges on the outer ring and one on the inner ring, NJ design bearings can accommodate axial displacement in one direction. An important feature is the separable design, which ease of assembly and fitting and axial location.
The inch four-row tapered roller bearing is one of the main roller bearings. This type of bearing has a large radial and axial capacity, and the radial load capacity is about three times that of a single-row tapered roller bearing. It can withstand large bidirectional axial loads, but the limit speed is low. It can limit the axial displacement of the shaft (or housing) in both directions within the range of the bearing axial clearance, so it can be used for bidirectional shaft positioning. The diameter and axial clearance of the bearing can be adjusted by changing the thickness of the spacer between the inner and outer rings. Mainly used for the work rolls of hot rolling mills and cold rolling mills, as well as the rolls of blasting machines.
Inch double-row tapered roller bearings increase the radial load capacity due to the increase in the number of roller rows, and at the same time, can also withstand large bidirectional axial loads. It is mainly used to bear the combined radial and axial loads mainly based on radial loads. It can limit the axial displacement of the shaft (or housing) in both directions, so it can be used as a bidirectional axial positioning.
Thrust Ball Bearings 54000U Series
Double direction thrust ball bearings consist of one shaft washer, two housing washers and two ball and cage thrust assemblies. The bearings are separable so that mounting is simple. The various parts can be mounted separately. The housing washers and ball and cage thrust assemblies are identical to those of the single direction bearings. Double direction thrust ball bearings can accommodate axial loads acting in both directions and can thus serve to axially locate a shaft in both directions. They must not be subjected to radial load.
Tapered Roller Bearings Four Row
Four-row tapered roller bearings have spacers for adjusting the clearance between the inner and outer rings. The performance is basically the same as that of double-row tapered roller bearings, and the bearing capacity is large. They are used almost exclusively in work roll applications such as rolling mills.
