Paired tapered roller bearings

Description

Paired tapered roller bearings
The IMCB product of the paired single row tapered roller bearing () is based on the universal dimensions of single row tapered roller bearings. Depending on the application requirements, the matching tapered roller bearings have different designs and types:
Paired bearings arranged face-to-face
Paired bearings arranged back-to-back
Paired bearings arranged in series
Basic design and IMCB Explorer bearings
The paired bearings listed in the product table constitute the basic IMCB product series. IMCB can provide other matching bearing sets upon request.
Characteristics and advantages
Low Friction
The optimized roller design on the edge and the surface smoothness of the edge () can promote the formation of a lubricant film, thereby reducing friction. This also reduces the heat generated by friction and edge wear. In addition, bearings can better maintain pre tension and reduce noise levels during operation.
long service life
The basic design of IMCB Explorer bearings includes a logarithmic raceway shape that optimizes the load distribution along the contact surface, reduces stress peaks at the roller end , and decreases sensitivity to misalignment axis deflection with conventional straight lines
Improve operational reliability
Optimizing the surface treatment of the contact surface between the roller and the raceway is beneficial for the formation of a hydrodynamic lubricating oil film.
Consistency of roller profile and size
The roller manufacturing tolerances and dimensional accuracy integrated into IMCB tapered roller bearings are extremely precise to the point where they are almost identical. This provides the optimal load distribution to reduce noise and vibration levels, and enables more precise pre tensioning.
Application of rigid bearings
A single row tapered roller bearing usually needs to be adjusted together with another tapered roller bearing. By applying a preload, rigid bearing applications can be achieved.
Running in phase with peak temperature decrease
Conical roller bearings usually have a running in period, during which conventional designed conical roller bearings experience significant friction, leading to wear. This impact will cause an increase in bearing temperature (Figure 1). Under the premise of accurate installation and lubrication of bearings, using IMCB tapered roller bearings can significantly reduce friction, wear, and frictional heat.
Separable and interchangeable
The inner ring (inner ring component) with roller and cage assembly can be installed separately from the outer ring. In addition, the separable components () are interchangeable. This helps with installing, disassembling, and maintaining inspection procedures.
