To determine the layout of a rolling bearing, we must first consider the bearing life, reliability and economy. In order to reach this policy, we should specifically list the factors affecting the bearing and the need to be satisfied. We said earlier: the bearing needs to be considered Some of the elements. We can refer to it:
How to list the factors that affect the bearing and the need to be satisfied? Can try to answer the following questions:
The orientation of the machine/equipment and bearing (requires a sketch.
Can the device space be clearly specified? Under the premise of not weakening the function of the machine; can the scale be changed?
Working conditions; including: ambient temperature such as load, speed, equipment space, temperature, environmental conditions, stiffness of the shaft and associated components? Can there be an external heat source or cooling device (temperature gradient between the bearing races)? What length changes in thermal expansion (can you swim the bearings)?
What is the ambient humidity? Can bearing equipment be dust-proof? What is the corrosiveness of the medium? Can the oscillation be transmitted to the bearing?
Is the axis horizontal, straight, and still skewed?
Can the deformation of the bearing housing be considered? Can you think about the misalignment caused by the deformation of the shaft?
Need: What is the number of bearing life required for life, accuracy, noise, conflict and operating temperature, smoothness, protection, equipment and disassembly? Can the depicted bearing be compared to other proven bearings? Can it be accounted for according to the revised life calculation method? What is the life of the machine itself (choose the bearing to have a price/performance ratio)?
Can you need higher rotation accuracy? For example, can machine support equipment require a uniquely low noise? Such as electric motors (in household appliances)
Can you need energy loss uniquely low? Is it necessary to constrain the temperature rise; avoid affecting the accuracy?
Can the smoothing method of the bearing in a specific environment be clear? Is the smoothness of the oil pool still smooth?
Is it possible to avoid leakage of smooth media in the bearing (eg in the food industry); to ensure the quality of the product produced? Can there be a gathering system for oil supply? Can bearings be protected from protection?
Can you use special equipment? Should the inner ring of the bearing be mounted on a cylindrical journal or a conical journal? The bearing is mounted directly on the journal; is it still fixed to the journal with a clamping sleeve or a withdrawal sleeve? Can bearings be often disassembled; such as rolling mill bearings?
Business conditions: What is the delivery time and quantity required for the bearing? When is the bearing to be used? Can I use a common bearing with a short delivery period? In a special working environment; is it necessary to use non-standard bearings or newly depicted bearings?
What are the radial and axial loads of the bearing and speed bearings? Can the load direction change? What is the speed? Can the direction of change change? Is there an impact load? When determining the scale, we should also consider the relationship between the load and the speed and the time allocation of each load and speed.

Stone Plastic Composite vinyl flooring is more and more popular new style eco-friendly vinyl flooring. SPC rigid flooring is set apart from other types of vinyl flooring by its uniquely resilient core layer. This core is made from a combination of natural limestone powder, polyvinyl chloride and some stabilizers.
SPC vinyl is a luxury vinyl flooring option with a structurally rigid, 100% waterproof core. SPC is also known as rigid core vinyl, and we use these terms interchangeably. Rigid core engineered vinyl flooring is designed to look like wood or stone, but requires less upkeep.
This flooring is durable, waterproof, and perfect for DIY installation. It`s ideal for both home and commercial areas.
