The correct measuring method for tolerance of inscribed circle diameter of needle roller:
1. In measuring, the inspected bearing and standard part should be under same temperature. The standard temperature for inspection is 20 .
2. As for the inspection of single minor inside diameter deviation Fwmin for package bearing roller set, it shall be inspected with limit plug gauge.

Inspection of Bearings
In accordance with ZBJ11020 standard and inspection regulations of the world needle roller bearing manufacturing company (such as Japan NTN, KOYO, Germany INA, American TORRINGTON). Since the punched outer ring has thin wall and is easy to be deformed in heat treatment, it is unnecessary to inspect the outside diameter of bearing before installation. Only when the inspected bearing is pressed into the standard housing bore, the final size and geographic accuacy can be obtained. The tolerance of housing bore size shall be in conformity with regulations (see Table -1). The inscribed circle diameter for needle roller will conform to the range of tolerance F8.






Construction
At the end of 2020, HL will relocate to a new production base, covering an area of 220,000 square meters, with a total investment of 150 million US dollars. There will be a national class bearing technology research and development center and R&Dand workshop,a nationally recognized laboratory, four modern dust-free production workshops and an intelligent storage logistics center. In the new production base, the technology R & D center and R & D workshop and the nationally recognized laboratory will have approximately US $ 15 million investment. The R & D center will be equipped with 40 senior R & D teams, using ROMAX simulation analysis technology to optimize product design and improve product life, simultaneously,independently designing and developing samples for products with customers' special needs. The laboratory is equipped with imported metallographic microscopes,three-coordinates machine, length measuring instrument, residual Austenite detectors, scanning electron microscopes and other physical and chemical testing equipment, vibrometers, performance testing machines and life testing machines.




The outer ring of drawn cup needle roller bearing is punched with the high-quality steel sheet. The outer ring has thin wall . The drawn cup needle roller bearing has the characteristics of small radial section area, large load carrying capacity, less inertia and economic manufacture. It is suitable for small section height, or when the housing bore isn't used for raceway, this type is recommended to use. The bearing is assembled into the housing bore under a certain pressure without further axial location.
The drawn cup needle roller bearing generally takes its shaft diameter as the internal raceway. However, the proper LR type inner ring can be used in accordance with application condition.
The drawn cup needle roller bearing has two structures - with retainer and with full of needles. They are divided into open-end type and close-end type. The structure with retainer has the single seal ring and double seal ring. The structure with full of needles has a large load carrying capacity.
CWN can provide all drawn cup needle roller bearings listed in this catalogue, including standard size and non-standard metric size, and inch-series as well as the high-precision drawn cup needle roller bearings with special requirements such oil hole in outer ring, double-row needles, nylon retainer, inner ring, seal ring, etc. (special technical requirement on order).




Quality control
1.HL Bearings passed the IATF 16949 approval by TUV Group in 2005. For many years, the quality system has been operating effectively.
2. With international bearing industry standards to ensure the interchangeability and consistency between the
supplied products and the world brand products.
3. HL's research and development center continuously optimizes product design, so that products continue to develop in the direction of light weight, reliability, low noise, long life and unitization.
