The six major processes of processing slewing bearing

Slewing bearing is also called the “big bearing”, carrying more complicated, such as: the radial, axial and overturning moment, been adopted by more and more mechanical equipment. slewing bearing according to the internal structure can be divided into: single row contact ball type, cross roller type, double row contact ball type, three rows of roller and flange type etc., according to the external form can be divided into: outer gear, inner gear, no gear, etc. All though there are differences, but the process is the same, the main process is as follows:

• Raw materials: purchase ingots from steel manufacturers, conduct material sampling and inspection, and the products are qualified for storage.
• Forging, enter the ring forging workshop, the specific process is shown in the figure below:

• machining

Into processing workshops, processing of forging before inspection, after passing before quenching for rough turning – lathe finish – raceway quenching and tempering hardness-quenching depth, crack detection-semi lathe finish after quenching-produce tooth- tooth quenching, tempering, and inspection-drilling, testing – fine grinding, – with clearance – assembly – – finished goods inspection, installation nameplate.

• packaging

Into the packaging workshop, cleaning packaging, wooden box packaging contains: product certificate, manual, material report, etc.

• logistics
