Key Manufacturing Process of Stainless Steel Ball Bearings
Selection of raw materials:
Select stainless steel materials suitable for making stainless steel bearings. Common ones include AISI 440C, AISI 304, AISI 316, etc.
Material pretreatment:
Pretreatment of raw materials, including cutting, forging, heat treatment and other steps, to form a shape and performance that meets the requirements of the bearing.
Cold drawing or hot rolling:
The pre-treated material is cold drawn or hot rolled to obtain the desired shape and size.
Sphere forming:
Stainless steel materials are made into spheres in bearings through processes such as cold forging, hot forging or injection molding.
Outer ring and inner ring forming:
The material is formed into the outer ring and inner ring of the bearing through cold drawing or cold heading processes.
Ball, outer ring, and inner ring finishing:
The ball, outer ring, and inner ring are finely processed to ensure that their size, shape, and surface quality meet the requirements.
Assembly:
Assemble the ball, outer ring, inner ring and other components, usually including bearing seats, sealing rings and other components.
Lubrication:
After assembly is completed, lubricate the bearing according to the usage requirements to ensure its normal operation.
Inspection:
Strict quality inspection is carried out on the manufactured bearings, including dimensional inspection, axial clearance inspection, rotation accuracy inspection, etc.
Packaging:
After inspection, the bearings are packaged to prevent damage during transportation and storage.

Installation and Maintenance of Sliding Block Bearings
Installation
- Preparation: Ensure that the work area is clean and check the condition of the bearings and shafts to ensure that there is no damage or contamination.
- Lubrication Selection: Select the proper lubricant and make sure grease or oil lubrication is appropriate for the work environment and load requirements.
- Bearing Preheating: If necessary, preheat the bearings using hot air or an oven to allow for easier mounting on the shaft.
- Correct Mounting: Use proper tools and techniques to mount the bearing on the shaft to ensure a good fit between the bearing and the shaft.
- Alignment Check: Ensure that the bearing is aligned after mounting to avoid additional loading due to improper alignment.
