Do you know characteristics of trapped roller bearing?

Trapped roller bearing have conical inner ring and outer ring raceway and conical roller.Tapered roller bearings can bear combined loads, that is, radial and axial loads acting simultaneously.The extension lines of the raceway meet at the same point on the bearing axis to achieve true rolling and thus have a low friction torque during operation.The axial load capacity of tapered roller bearing increases with the increase of contact Angle a.The size of the contact Angle, usually between 10° and 30°, is related to the calculated coefficient e: the larger the value of e, the larger the contact Angle.
Trapped roller bearing characteristics:

Low friction
The optimized roller design and surface finish can promote the formation of lubricant film and reduce friction.This also reduces the heat generated by friction and flange wear.In addition, the bearing can better maintain pre-tightness and reduce the noise level during operation.
Long service life
Basic design of trapped roller bearing and convexity raceway logarithmic raceway shape optimizes load distribution along contact surfaces, reduces peak stress at roller ends, and reduces sensitivity to counterbalance shaft deflection with conventional straight lines.

Improve operational reliability
The optimized surface treatment of the contact surface between roller and raceway is beneficial to the formation of hydrodynamic lubricating film.
Roller contour and size consistency
The roller manufacturing tolerances and dimensions integrated into trapped roller bearing are so precise that they are almost identical.This provides an optimal load distribution to reduce noise and vibration levels and enables more accurate preloading.
Rigid bearing application
A single row trapped roller bearing usually needs to be adjusted together with another trapped roller bearing.The application of rigid bearing can be realized by applying preload.
