3.Recommended range
We offer a recommended range of 42 items balls and crossed rollers designs in
size range from 400 mm to 1900 mm
• Easy to select
• From stock
• Interchangeable
• Cost effective solution
• Compete with market leaders
• Reference range for new products
Ball design -is a simple design for low demanding applications and allows
• A better static capacity for oscillating movements

5.Production process-XU300515-N bearing
The production process of bearings in mechanical processing plants refers to the whole process of making products from raw materials or semi-finished products. For bearing production, it includes transportation and preservation of raw materials, preparation of production, manufacture of blank, processing and heat treatment of parts, assembly, debugging and packaging of products.
The content of production process is very extensive. Modern enterprises use the principles and methods of system engineering to organize and guide production, and regard production process as a production system with input and output. In the production process, the process of changing the shape, size, position and properties of the production object to make it a finished product or semi-finished product is called technological process. It is the main part of the production process.
The bearing process refers to the part of the process that one or a group of workers continuously complete on the same workpiece or several workpieces at the same time on a machine tool or a working place. The main characteristics of a working procedure are that the processing objects, equipment and operators are not changed, and the contents of the working procedure are continuously completed.
To formulate the bearing machining process, it is necessary to determine several working procedures and the sequence of working procedures. The drafting of the process route is to formulate the overall layout of the process. The main task is to select the machining method of each surface, determine the machining order of each surface, and the number of working orders in the whole process. The formulation of bearing process route must follow certain principles.
When machining precision bearing parts, we must first work out the machining process of mechanical parts to ensure that every link is normal. In the machining of precision mechanical parts, grinding is used to produce and process various metal materials and metal materials, and can produce and process plan,
