● Introduction
6211 ZZ bearing is single row deep groove bearings. It is produced by our company in accordance with the national standard GB/T 276-2013. The company is equipped with advanced processing and testing equipment, equipped with professional testing department and has a perfect quality control system to ensure the material, dimensional tolerance, clearance, noise and vibration of the bearings meet the standards. Bearings are mainly subjected to pure radial load, and can also be subjected to radial load and axial load at the same time. Due to the existence of radial clearance of the bearing, the actual contact angle will be increased under the axial load, so the variation of contact angle should be considered when determining the axial load capacity. The bearing has small friction coefficient and high limiting speed. The steel balls meet the standard GB/T 308.1-2013, the material of steel balls is GCr15, the grade of steel balls is 10. The production process of steel balls is raw material upsetting, light grinding, heat treatment, surface strengthening, hard grinding, primary grinding, appearance, fine grinding, cleaning, inspection, rust prevention and packaging. Bearings are widely used in tractors, pumps, transmissions, engineering machinery and other fields.
● Production Details
The quality indexes of collar turning include surface quality and machining accuracy, which are reflected by technical conditions. Bearing collar turning technical conditions due to the technical level of production enterprises, bearing precision level and other different, turning processing technical conditions bearing industry is not yet a unified quantitative standards. When turning the collar in the tool sharpening to appropriately increase the front angle and tip edge inclination angle, reduce the radius of the tool tip member arc, in order to increase the tool "sharp" degree, and appropriately reduce the amount of tool feed, increase the spindle speed to match, in order to reduce the cutting resistance. Bearing parts carburizing equipment, small and medium-sized and large rings, large quantities and few varieties can be processed in the push rod type continuous gas carburizing furnace production line. Medium batch, multi-species, can use the roller bottom type continuous gas carburizing furnace processing.

● Products Precision
Rolling bearing is an extremely widely used standard part in the machinery manufacturing industry, it is generally composed of outer 1, inner ring, rolling body 3 and cage. Outer ring and outer shell hole with, inner ring and transmission shaft journal with, belong to the canonical smooth cylindrical connection. But because of its structural characteristics and functional requirements, its tolerance fit, and general smooth cylindrical connection requirements are different.

● Noise and Vibration
In the case of a close fit between the bearing ring and the housing or drive shaft, the bearing ring may be deformed by the shape of the adjacent parts. If there is deformation, it may produce vibration in operation. If there are impurities such as dust in the rolling bearing, there will be non-periodic vibration and the so-called dust sound, the size of vibration and noise is not determined and may or may not be present.
