How to Use NTN Bearing Correctly to Prevent Damage

  • The installation space of NTN bearing can be accommodated in the bearing installation space. Because the rigidity and strength of the shaft are paid attention to when designing the shaft system, the shaft diameter, i.e. the inner diameter of the bearing, is generally determined first. However, rolling bearings have a variety of size series and types, and the appropriate bearing type should be selected from them.
  • Load the size, direction and nature of the bearing load [the load capacity of the bearing is expressed by the basic rated load, and its value is contained in the NTN bearing size table] the bearing load is rich in changes, such as the size of the load, whether there is only radial load, whether the axial load is unidirectional or bidirectional, the degree of vibration or impact, etc. 
  • After considering these factors, we can choose the appropriate bearing type. Generally speaking, the radial load capacity of bearings with the same inner diameter increases in the following order: deep groove ball bearing < angular contact ball bearing < cylindrical roller bearing < tapered roller bearing < self-aligning roller bearing
  • The bearing type whose speed can adapt to the mechanical speed [the limit value benchmark of bearing speed is expressed by the limit speed, and its value is contained in the NTN bearing size table] the limit speed of the bearing is not only taken from the bearing type, but also limited to the bearing size, cage type, accuracy grade, load conditions and lubrication mode. 
  • Therefore, these factors must be considered in the selection. The following bearings are mostly used for high-speed rotation: deep groove ball bearings, angular contact ball bearings and cylindrical roller bearings
  • Rotation accuracy bearing type with required rotation accuracy NTN bearing dimensional accuracy and rotation accuracy have been standardized by GB according to bearing type] machine tool spindle, gas turbine and control machine require high rotation accuracy, high speed and low friction respectively. At this time, bearings with accuracy above grade 5 should be used. The following bearings are generally used: deep groove ball bearing, contact ball bearing and cylindrical roller bearing
  • A. Improper operation:How to Use NTN Bearing Correctly to Prevent Damage
  • Improper installation, operation or removal may cause deformation or damage to the cage
  • Precautions: use appropriate operation, installation and disassembly tools
  • B. Insufficient lubrication:
  • Insufficient or improper lubrication may result in component scratch or serious bearing deformation
  • Preventive measures: improve the lubrication system and supplement or replace the lubricant regularly and properly
  • C. Rust and corrosion:How to Use NTN Bearing Correctly to Prevent Damage
  • Contact with water may cause corrosion and rust of bearing elements. The corroded NTN bearing may peel off during operation
  • Preventive measures: check the seal regularly to ensure good sealing effect and store the bearing correctly
  • D. Current:How to Use NTN Bearing Correctly to Prevent Damage
  • Energizing the bearing while it is rotating may cause grooves or nicks. When the NTN bearing is stationary, improper grounding of electrical operation will cause slight burns
  • Precautions: before welding components other than NTN bearings, reduce or avoid current through the bearing through appropriate grounding connection

  • Abrasive particle contamination and debris intrusion can cause wear, scratches and dents on the working surface of NTN bearings
  • Lubricant, particle intrusion prevention, inspection and debris removal
  • F. Eccentricity:
  • Eccentricity, inclination or excessive load may lead to geometric stress concentration or surface spalling
  • Preventive measures: accurately process the bearing seat and shoulder
  • For the periodic maintenance and operation of NTN bearing equipment and the replacement of peripheral parts, when the search and inspection of the disassembled bearing is suspended, it is necessary to judge whether the secondary bearing parts can be reused and record the good or bad application conditions.How to Use NTN Bearing Correctly to Prevent Damage

Our ball bearings are available to you off-the-shelf in sizes ranging from 10mm to 320mm outside diameter. Contact us for the latest ntn ball bearing catalog and buy ntn bearings online.

Deep groove or single row radial ball bearings are the most widely used bearings in all general industries. They utilize uninterrupted raceways, making them the best choice for radial loads. NTN radial ball bearings are usually fitted with pressed steel cages but are also available in machined brass or molded nylon. As a ntn ball bearing supplier and distributor,we also offers bearings with locating snap rings on the outside diameter.

Deep Groove Ball Bearings

Single Row Angular Contact

Single row angular contact ball bearings have raceways with high and low shoulders. These opposing raceways are designed to carry thrust loads in one direction. NTN can preload bearings at the factory to produce the correct load when the bearing is put into service. Bearings in this series are fitted with a specific internal clearance so that they have a specified contact angle under load. The standard contact angle used by NTN is 30°, but in many cases a 40° contact angle can also be specified. We also offer special high-speed bearings with phenolic resin cages and 15° contact angles.

Single Row Angular Contact

Double Row Angular Contact

Double row angular contact ball bearings have an inner and outer ring with double raceways. The orientation of the two rows is such that the contact angle is similar to a pair of back-to-back single row bearings. NTN’s 5200 and 5300 series offer a one-piece inner ring double row raceway that can accommodate thrust loads in either direction. The 3200 and 3300 series have filler grooves so installing them requires a thrust load on the unnotched face of the ring.

Double Row Angular Contact

Insulated Ball Bearings

Electrical pitting often occurs in bearings used in electrical equipment such as electric motors and generators due to current leakage. Currents present in the vicinity of the bearing can flow through the bearing causing the current to arc between the rolling elements and the rolling surfaces. The generated arc will increase the temperature of the steel at the arc point and change the material structure of the steel, which will eventually cause the bearing to fail. Coated bearings or ceramic hybrid bearings can prevent this electrical pitting.

Insulated Ball Bearings

Speciality Ball Bearings

Double row self-aligning bearings use an inner ring with a single spherical raceway. In this configuration, the inner and outer rings may be misaligned with each other. The boundary dimensions of self-aligning bearings can be the same as standard ball bearings.We are a professional NTN bearing supplier with decades of experience in manufacturing Speciality Ball Bearings.

Spherical roller bearings are designed for extremely demanding applications and must be able to withstand high loads, severe misalignments, contaminated environments, shock and vibration. And since a plant near you offers the highest load ratings and production volumes in the industry, there’s no reason to look elsewhere for spherical roller bearings.We are a professional NTN bearing supplier with decades of experience in manufacturing spherical bearings.

Spherical Roller Bearing

NTN tapered roller bearings are designed for the most demanding applications in industries such as mining, forestry and steel fabrication. Utilising a tapered roller and raceway arrangement where the rollers and raceways meet at a common apex, NTN’s tapered roller bearing rollers are guided by contact between the large ends of the rollers, providing high capacity for radial and single thrust loads. With nearly 100 million tapered roller bearings produced annually under the NTN and Bower brands, NTN bearings rival all major competitors in the market.

Tapered Roller Bearings

These bearings use cylindrical rollers as rolling elements and have a high load carrying capacity. The rollers are guided by a retaining edge on the inner or outer ring. The inner and outer rings can be separated to facilitate assembly, as they are usually press-fitted to the shaft and housing respectively. This makes cylindrical roller bearings ideal for applications where the shaft is subject to thermal expansion, such as electric motors. We are a professional NTN bearing supplier with decades of experience in manufacturing Cylindrical Roller Bearings.In addition to normal cylindrical roller bearings, we can also produce insulated cylindrical roller bearings.

Cylindrical Roller Bearings

Needle roller bearings use small needle rollers (6mm diameter or smaller) as rolling elements. These bearings have a smaller cross-section, higher load carrying capacity, higher stiffness and lower inertia forces, helping to reduce the size and weight of machinery. They are designed to withstand vibration, operate in harsh conditions and are interchangeable with plain bearings.We are a professional NTN bearing supplier with decades of experience in manufacturing Needle roller bearings.
