ARJG bearing's most fundamental difference is:
Most manufacturers make products mainly considering cheap price, but we make products considering the quality and service life. Each of the bearings we produce is entirely implemented with the international standard. Our bearings exist for the quality and brand, you could never find out our products' defects in quality. ARJG, provides you with the most professional engineering machinery rolling bearings.
Let's share with you what details of processing does a good rolling bearing have got. How to identify the bearings?
The identification of the bearing
For the low cost pursue, some small manufacturers print the black stamps on the bearing to identify models and manufacturers with some very simple equipments and templates.
Formal manufacturers use laser engraving, the stamps are deep and have obvious dents with hand touch, good-looking, with no breakpoints, and could never disappear. This improves the bearing grade obviously.
The use of bearing retainer
The selection of bearing retainer is very important. Because once too much dust stuck into the bearing, the retainer will be first worn. If the bearing retainer is broken, the bearing will be directly broken. Quality bearings use big rivets to thicken the retainers. Our bearings are completely in accordance with the process, so each piece of ours is of high quality.
Bearing material and hardness
Quality bearing must be made of bearing steel, named "High Carbon Chromium Bearing Steel (Fully quenched class) GCr15". At present the standard hardness of rolling bearing is 60-65 degree, while hardness of the ring is 61-62 degree, and ball is 64-65 degree. A simple way to identify the bearing is to see if its hardness is over 60 degree, because only bearing steel can get over this degree.
Grease selection of the bearing
Many customers ignore this key point. The bearing should work for a long time, so this has to be guaranteed by enough grease. And this should also be taken into account of working in different seasons and environment.
Special note: please choose high temperature grease if the working environment is over 120 °C and low temperature grease if it is below -20 °C.

FAQ:
I couldn't find a design to fit my application in your catalog. Can you help me design a bearing?
Yes, technical expertise is available to assist you with engineering design for custom products. The available options include, but are not limited to: custom rings, retainers, balls, shields, lubricants, and packaging. We look forward to working with you to satisfy your certain requirements.
What causes bearing noise?
Bearing noise is a function of both the bearing and the way it is used. Some external factors that cause bearing noise include lubricant type, excessive bearing load, improper installation, and so on. Once the abnormal noise occurred, you can contact our engineers, we will help you find the reasons and provide appropriate solutions.
What is the difference between using a shield or a seal as a ball bearing closure?
Shields or seals are often installed to retain lubricant and to prevent contamination from entering the bearing. The shield only contacts the outer ring and does not contact the inner ring, while the seal generally comes in contact with both the inner and outer rings, so the seal provides a higher degree of protection against the contamination.
ARJG developed a series of bearing solutions for different applications. Please contact an ARJG engineer for technical assistance with any requirements.
