How To Calculate Load For Roller Thrust Bearing?

- Jun 16, 2020-


A ball bearing with a load capacity of p = 0.5 is able to accommodate a significant axial thrust load. The calculation is somewhat complicated as it depends on the thrust and contact angle at which the bearing develops. If a combined radial and axial load occur, the equivalent bearing loads (p) used in the service life formula must be calculated for each bearing and calculated in combination. Rolling bearings that taper are more likely to carry significant axial drawers. 


The calculator determines the efficiency of the pulley supported by the contact bearing. It would be too difficult to show you how to calculate p for each type of bearing shown in the service life formula for a ball bearing with a load capacity of 0.5. 

The four contact points of a ball bearing are usually exposed to a combination of two or more loads wherever they are used. The bearing is able to withstand radial thrust and torque loads, but not thrust to torque loads. 


Axial ball bearings, which consist of a ring supporting the bearing ball, are often used in applications with low axial pressure. Other bearings, rotating parts are permitted, but they are designed to carry mainly axial loads. It is often seen as a rotating part of the ball bearing with infinite life and infinite rotations. 


They are arranged flat, with axles pointing to the bearing axis, and often have a bearing capacity of 1,000 to 1.5 times that of cylindrical thrust bearings. Bearings, such as bearings and ball bearings, often had a capacity to carry loads of up to 2,500 to 3,200 pounds per square inch. 


By using high-performance bearings at the output shaft location, from extruder manufacturers and end-users, users can increase the power density of their extruders by increasing the bearing dimensions. Spherical roller bearings offer the best combination of power and load capacity of any other type of thrust bearing. They can be replaced by existing thrust forces while simultaneously increasing power densities and output loads. 


Spherical roller bearings, in which the axial thrust is supported by a thin layer of pressurized liquid, exhibit less resistance than their liquid bearing counterparts.


They offer very good load-bearing capacity and tend to wear faster than high ball bearings where there is no difference in radial speed or friction. They are cheap and can be used where they are needed (for example in Zippe centrifuges), but they do not wear well enough to be worn out as the difference between radial speeds and ball bearing friction is greater. 


Tapered roller bearings consist of small tapered rollers arranged in such a way that their axis converges to a point on the bearing axis. Such types are 9C, but you need to calculate the right cone to provide enough pressure to gently roll the end of each roller over the brow of the bearings without spinning. A self-aligning ball bearing with a spherical roller bearing that pushes at a radial speed equal to or greater than the speed of friction between the ball bearings. 

The angle of the inclination of such bearings depends on the type and size of loading. Spherical roller bearings are also designed for radial rolling and bearing clearance. A small misalignment can be compensated by assuming that the ball bearing is relieved by low friction between the rollers on its axis and the bearing axis. 


The calculation of the bear analysis is efficient because it can be used to simulate the dynamics of a complete machine system. The input is defined and implemented in the block diagram in Figure 1, where the input is defined as a ball bearing and the output as a bearing field. 

A bearing with a full number of rolling elements has an angle contact angle of 45 degrees to the axial loading of the ball bearing, which shifts in one direction. The contact line between the bearings is a direct line from the bearing field to a contact point in the body. A bearing, which is mainly designed for axial loads and thrust forces at angle contacts, has a contact angle of 45 degrees. Depending on the design, this thrust can be transferred from one direction to another on an axial load or vice versa. 


Compared to ball bearings, spherical roller bearings have three main advantages in terms of load-bearing capacity - load-bearing capacity, lower bearing wear, and lower costs. 


The production rate of an extruder can be increased by effective handling of the increased drum pressure in the extruder machine. The thrust bearing can withstand high axial loads, and the increased pressure is mainly dependent on the thrust of the bearing. Table 5 - 9 describes the load capacity and pressure when loading the bearings. 


The axial load at 90Adeg can be calculated with the following equation. When tapered roller bearings are face-to-face and back-to-back, tapered roller bearing axials increase by 1.5% when applied face-to-face and 2.0% when tapered backward.
