Product Description of INA Bearing
- Needle roller bearings have a large carrying capacity and are suitable for supporting structures with limited installation dimensions.
- The surface of the journal is hardened as the rolling surface, and the bearing is fitted into the seat hole with a press fit, and there is no need for it to be axially positioned.
- The bearing should be injected with an appropriate amount of grease before installation.
- Usually, no relubrication is required after assembly (BK type bearings are used in the support of the journal without the protruding end, the end face is closed for sealing, and can withstand small axial movement.)

INA Cylindrical Roller Bearing
A single row cylindrical roller bearing with a cage is a unit composed of solid inner and outer rings, cylindrical rollers and cage components. There are rigid ribs or no ribs on both sides of the outer ring, and the inner ring has one or two rigid ribs or no ribs. The cage prevents the cylindrical rollers from contacting each other during the rolling process. Cylindrical roller bearings are available with or without cage.

There is nothing that cannot be improved. We have developed TB rollers to significantly increase bearing life under axial load. TB is the same as in TorusBallig (ring shape). The special curvature of the roller end surface enables the load to be distributed over a larger surface area. The curved roller end surface increases the size of the contact surface, thereby significantly reducing the contact pressure.
INA sliding bearings, maintenance-free and maintenance-free steel and bronze sliding bearings
Plain bearings and rod end designs that require maintenance using steel/steel and steel/bronze materials are easy to maintain, cost-effective, and very suitable for alternating loads. Common bushings, gaskets and strips are made of low-maintenance metal polymer composite material E50. The sliding layer has a lubricant pocket, which means that the initial lubrication is sufficient in most cases.
INA maintenance-free sliding bearings.
Schaeffler offers a comprehensive catalog of maintenance-free plain bearings. Innovative plain bearing materials are used here, such as ELGOGLIDE, ELGOTEX and metal polymer composite E40. These PTFE sliding bearing materials provide ultra-low coefficients of friction for spherical plain bearings and rod ends, as well as bushes, washers and strips, while ensuring low wear and a very long life cycle. Maintenance-free sliding bearings greatly reduce lubricant and maintenance costs because they do not require any oil or grease and are also very environmentally friendly.
- Needle roller bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. This type of roller is called a needle roller.
- Needle roller bearings are equipped with thin and long rollers (roller diameter D≤5mm, L/D≥2.5, L is the length of the roller), so the radial structure is compact, especially suitable for the support structure with limited radial installation size .
Drawn cup needle roller bearings
- Drawn cup needle roller bearings are needle roller bearings with a thin drawn cup outer ring.
Features: The section height is very low and the load bearing capacity is high. - Place: It is mainly used for bearing configuration with compact structure and low price, and the inner hole of the bearing box cannot be used as the raceway of the needle roller cage assembly. Bearings and bearing housings must be installed with an interference fit.
- Drawn cup needle roller bearings generally do not have an inner ring.
Solid Ring Needle Roller Bearings
- Composition: One or two ferrules and a needle roller set with a cage.
Classification: It can be divided into bearings with inner ring or without inner ring.
Features: Solid ferrule needle roller bearings have smaller volume and higher load capacity. - Applicable places: Solid ferrule needle roller bearings can meet the requirements of light weight, small space occupation and high transmission power.
Combined Needle Roller Bearings
- Combination: Needle roller bearing is a bearing unit composed of radial needle roller bearing and thrust bearing components.
- Features: compact structure, small volume, high rotation accuracy, can bear a certain axial load while bearing a high radial load. The product structure is diverse, adaptable and easy to install.
- Applications: It is used in various mechanical equipment such as machine tools, metallurgical machinery, textile machinery and printing machinery, and can make the mechanical system design very compact and dexterous.
Application of INA Bearing
- Depending on the field of activity and application, needle roller and cage assemblies can be integrated between the rings to strengthen the assembly and ensure the connection between the various mechanical parts.
- Therefore, needle roller bearings come in many forms (cages, bushes, bearings with solid rings, combination bearings, needle roller thrust bearings, cam followers, etc.) to meet all technical constraints of the industrial market.
- The smallest cross-section in a rolling bearing is Needle roller and cage assemblies provide a very compact solution for applications where space is limited.
High load capacity
- Due to the large number of rollers, the needle roller and cage assembly has a high load-carrying capacity.
high stiffness - The needle roller and cage assembly has high stiffness due to the large number of small diameter rollers.

FAQ
Due to their internal design, ball bearings cannot usually be disassembled down to the component level; therefore, they cannot usually be refurbished.
Solid base shells are manufactured without cavities and fillers; they are stronger than hollow bases, and there are no traps for bacteria and fungi to grow. In the thermoplastic shell, the sturdy base will not break under steam or high-pressure washing. The hollow base saves material and weight to reduce costs. Some people use epoxy resin to backfill the hollow base to eliminate the trap of bacteria breeding, but this will not increase the strength, will cause the installation surface to be uneven, and water will seep between the shell and the filling material, causing cracking.
Use particularly thermally stable bearing rings, larger internal clearance (C4), specially selected lubricants that will not decompose at high temperatures, and zinc anodized flinger. There are two basic versions of our high temperature bearings. The suffix “C4HR5” represents the bearing that can withstand 400°F, and the suffix “C4HR23” represents the bearing that can withstand 450°F.
For critical applications such as pulp and paper processing, printing and packaging, material tearing can cause expensive downtime due to excessive torque and vibration.
The two biggest factors affecting the starting and running torque of the bearing are the seal design and lubricant selection. The shaft and bearing seat fit, component accuracy and surface finish, and retainer design also have some influence.
In higher speed applications, non-contact sealing devices are usually required to minimize operating torque and heat generation, so oil baffle rings and secondary sealing devices are usually required. Flowing oil lubrication systems are usually the best solution.
After proper installation, most seated bearings only need to be relubricated regularly with a small amount of grease and checked to ensure that they operate at low temperatures, quietness, and sufficient accuracy.
This depends on many factors, such as the application’s load conditions, operating speed, duty cycle, temperature, and operating environment. The technical information section of this website provides some basic information. Our engineers can help you determine more specific theoretical life calculations.
When noise and/or operating temperature increase or operating accuracy decreases, bearings should be replaced.
Lubricant of choice

The noise emitted by the bearing may be caused by a combination of one or more factors, such as insufficient working clearance, excessive working clearance, changes in working clearance due to temperature, damage to the contact area, contamination, inappropriate lubricants or The raceway is damaged.
Lubricants have five basic functions for bearings:
Reduce friction
Reduce wear
Reduce temperature rise
Minimize corrosion
Seal contaminants
We do not recommend mixing grease. Mixing incompatible greases will cause the mixture to harden, preventing it from releasing any oil. Mixing incompatible greases can also soften the mixture, which releases all the oil. In either case, the mixture will not be able to properly lubricate the bearing. We strongly recommend using the same type of grease originally provided with the bearing.
