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.
Spherical roller bearing with relubrication features.
This type bearing has many advantages such as:
Accommodate misalignment
High load carrying capacity
Relubrication features
Low friction and long service life
Increased wear resistance
Single row deep groove ball bearing housings are the most widely used bearing types:
1. Basic design of open bearing
2. Sealed bearings
3. ICOS oil-sealed bearing unit
The components of the self aligning ball bearing include two rows of balls, a cage, an inner ring, and an outer ring with a common concave sphered raceway.This type of bearings is self-aligning and insensitive to angular misalignments of the shaft relative to the housing. The bearings are produced in several design: open bearings with the basic design, sealed bearings, open bearings with an extended inner ring.The self alignning ball bearings have the lowest friction of all rolling bearings.The bearings are available with a cylindrical bore or with a tapered bore in certain size ranges.
Truck hub units, which contain two tapered roller bearings, are pre-adjusted, greased and sealed at the factory in order to simplify installation. The wheel bearing units are intended for use in truck, trailer and buses. They are designed to withstand typical harsh operating conditions and require less maintenance than the conventional wheel bearing sets they replace. Some variants have an integrated impulse ring which makes some variants suitable for use with anti-lock braking systems. The units can also save time and cost during brake maintenance.
Single-row tapered roller bearings can withstand radial and axial loads mainly based on radial loads, while large taper angle bearings can withstand radial and axial loads mainly based on axial loads, and additional radial loads are generated under the action of radial loads. axial force. Therefore, it is generally configured in pairs and can withstand radial loads. If used alone, the external axial force must be greater than the additional axial force.
UCP series housed units feature the set screw locking (UC) bearing insert. Pillow (plummer) block ball bearing units consist of an insert bearing mounted in a cast iron housing that can be bolted to a support surface. This variant is strong and stiff, and is suitable for applications with both constant and alternating directions of rotation. It has an inner ring extended on both sides and is locked onto the shaft by tightening a set screw on the inner ring, making it easy to mount. Housing designed for ease of bearing replacement.
3300 series double row angular contact ball bearings are non-separable and have a ball-loading notch on one side. It can bear large radial and axial bidirectional combined loads and moment loads mainly based on radial loads. It can limit the bidirectional axial displacement of the shaft or housing, and has better rigidity than single-row bearings. Bearings are available in open and sealed designs. Sealed bearings are maintenance-free and thus allow economical bearing arrangements.
Cylindrical roller thrust bearings can be split into thrust cylindrical roller and cage assemblies, shaft washers and races. Such bearings can withstand large axial loads in one direction, but cannot withstand radial loads, and they do not have self-aligning capabilities. Mainly used in heavy machine tools, high-power marine gearboxes, oil drilling rigs, vertical motors and other machinery.

Excavator bearings play a crucial role in the production and maintenance of excavators. As a critical component, these bearings are responsible for supporting the load and enabling smooth rotation of various moving parts in the excavator, such as the boom, arm, and bucket.
The knocking force is generally applied to the inner ring of the bearing, and the knocking force of the shielding machine room should not be applied to the rolling element and cage of the bearing. This method is simple and easy to operate, but it can easily damage the bearing. When the bearing is located at the end of the shaft, use a copper rod or other soft metal material smaller than the inner diameter of the bearing to support the shaft end, and add a cushion block to the lower part of the bearing. Gently tap with a hammer to remove it. When applying this method, attention should be paid to the appropriate position of the cushion blocks and the correct point of application.
Tapered roller bearings have tapered inner and outer raceways, with tapered rollers arranged between them. The projection lines of all conical surfaces converge at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for bearing composite (radial and axial) loads. The axial load capacity of bearings is mostly determined by the contact angle α Determined; α The larger the angle, the higher the axial load capacity. The angle size is represented by the calculation coefficient e; The larger the e-value, the greater the contact angle, and the greater the applicability of the bearing to withstand axial loads.
The dismantling of bearings is a regular maintenance process, which is carried out during bearing replacement. After disassembly, if it is necessary to continue using or check the condition of the bearings, the disassembly should also be carried out with the same care as during installation. Pay attention not to damage the various parts of the bearing, especially the disassembly of interference fit bearings, which is difficult to operate.
