Tapered roller bearings

• The four-row taper roller bearings are the most commonly used roller neck bearings. The loading capacity is large and can withstand the radial tipping load with radial loads. Therefore, it is often used in the occasion that to withstand radius and axial loads at the same time.

• The internal structure of the four-row taper roller bearing can disperse loads and reduce local pressure and wear, thereby improving the life and reliability of the bearings. In addition, this bearing can also run in high-temperature and low-temperature environments, suitable for various application scenarios.

• 
  

• The characteristics of the four-row taper roller bearings

• Successfully applied to heavy mechanical equipment such as rolling machines, can be successfully used on low-speed to medium-speed rolling machines and with radial and axial loads.

• Due to its design structure, it can meet the application requirements of high speed, high accuracy, and high load.

• The internal structure can disperse loads to reduce local pressure and wear, thereby improving the life and reliability of the bearings.

• Suitable for the occasion that it can withstand the radial and axial load simultaneously and can withstand larger radial and axial loads.

• 
  

• In short, the four-row taper roller bearings are high-performance in mechanical equipment suitable for heavy loads, high-precision, and high speeds. They can withstand radial and axial loads but must be maintained frequently.

• 
  

• The material for four-row tapered roller bearing 

• The material choice of the four-row taper roller bearings is very important because the material of the bearings directly affects its performance and life.

• The materials that can be chosen include GCR15, GCR15Simn, GCR18MO, and carburizing steel. These steels have good hardening and abrasion resistance.

• For large-sized four-row taper roller bearings, FV Bearing will also use imported carburizing steel according to the actual working conditions of the customer, such as Timken 33311 from the United States, carburizing steel from European OVAKO.

• 
  

• The types of FV BEARING can supply Four-row taper roller bearing 

• FV produces this style of bearings in two base designs, TQO and TQI configuration, where the main difference is the mutual arrangement of the roller complements and the number of inner and outer rings dictated by this.

•  

• The TQO type is composed in its standard configuration of two double cone assemblies, one central double cup, two single cups, and factory-adjusted cup and cone spacers.

• The TQI type is composed in its standard configuration of one double cone assembly, two single cone assemblies, and two double cups.

• 
  

• A four-separated individual single-cup configuration is also available. This design facilitates the reworking of the bearing.

• 
  

• FV BEANG can provide the sealed type of four-row taper roller bearings.

• The sealing parts installed on both sides of the bearing suite are produced in several designs based on the size and application needs of the bearings. FV Bearing can provide the most commonly -integrated side unified sealing parts (European version). The comprehensive site is Narrow sealing (compact seal concept) and loose flange horizontal unified sealing parts (Japanese version).

• 
  

• Delivery period of four-row taper roller bearings

• According to different materials, the delivery period of the four-row taper roller bearings is different.

• If GCR15, GCR15SIMN, or GCR18MO, the delivery period is 35-40 days

• If carburizing steel is used, the delivery period is 80-90 days.

•
