● Introduction

INA roller bearings are produced by INA Corporation. Founded in 1946, INA is headquartered in Nuremberg, Germany. Since its establishment, it has become a world leader in the field of needle roller bearings, and quickly expanded from the original needle roller bearing field to a wide range of products. It has been committed to product innovation to meet the needs of customers and provide high-quality products, making it the world's leading supplier of rolling bearings and a recognized partner of automobile manufacturers. In 1995, INA company started to invest in China. It has many manufacturing plants and many service units in China. We maintain good cooperation with INA company and can distribute INA roller bearings.

INA bearings are widely used in agricultural machinery, construction, hydraulic and wind engineering, construction machinery, machine tools and manufacturing machinery, material handling and packaging, port engineering, power tools, gearboxes, and the semiconductor industry.

● Bearing Series

The types of the bearings include needle roller bearings, spherical roller bearings, tapered roller bearings, cylindrical roller bearings and track rollers.

● Production Details

◆ Methods to suppress grinding crack

1. The carbide mesh, ribbon, liquid analysis and annealing tissue of raw materials should be strictly controlled.

2. Scientifically select the heat treatment process.

3. Alloying of material design, so that there is high fracture strength and no micro-crack defects after heat treatment.

4. Reasonably increase the decomertion process in the machining process and reduce the machining stress.

5. Reasonable selection of grinding wheel material, particle size, rotation speed and feed to reduce grinding heat.

6. Reasonable selection of coolant and cooling method.

◆ Forming method for grinding surface of bearing ring

The grinding and forming methods of each surface of the bearing ring mainly include two categories: the trajectory method and the forming method. Since the surface of the bearing ring is a body of revolution, the shape of the wire on the forming surface adopts the trajectory method, and it is a ring located on the plane of the rotation direction of the bearing ring. The formation of the busbar on the grinding surface of the ring also has two methods: the trajectory method and the forming method. Therefore, the forming methods of the grinding surface of the bearing ring are the trajectory-trajectory method and the forming-trajectory method.

● Bearing Instant Demagnetization

Instant demagnetization refers to a demagnetization method in which the workpiece is demagnetized immediately after being charged on the machine tool. It can be carried out directly on the magnetic cassette, or an demagnetization device can be installed in the feeding part of the machine tool for demagnetization. The latter can easily control the residual magnetism below 1mT, that is to say, demagnetizer with poor demagnetization energy can be used at this time. The advantage of instant demagnetization is that it can avoid residual magnetic aging, avoid repeated magnetization and complex effects. It can demagnetize the upper magnetic part and give full play to the ability of the demagnetizer.
