Eric Bearing LTD has enough stock for FAG QJ306 bearing

For bearings deployed in the agriculture sector there is no shortage of potential hazards, including moisture, soil dust, corrosive fertilisers and very high shock loads (such as those generated by stone chipping). However, the robust bearing design and highly effective sealing of NSK Agri Disc Hubs makes them a proven choice in extreme operating conditions. Manufactured in Germany, these innovative units are a popular choice for common farming implements such as short disc harrows, seed drills and flail mowers.Extremely harsh working conditions, along with high-pressure washing routines, place a raft of demands on the bearings and seals found in equipment for the agriculture industry. A low-quality bearing will not be sufficiently robust in its design or performance levels to provide the uptime necessary for reliable and productive operation. Instead, frequent downtime and costly failures will be the likely result.

NSK’s solution to this challenge is the Agri Disc Hub, a cost-effective, self-lubricating bearing unit that delivers a number of major benefits to users of farming implements. High-performance Agri Disc Hubs feature double-row angular-contact ball bearings that can support high axial and radial loads, while the meticulously devised configuration locates the bearings within a sturdy housing that connects directly (and simply) to the implement via an integrated flange.

Importantly, NSK can offer fast, Europe-wide availability of Agri Disc Hubs as manufacturing takes place in Germany. The Munderkingen facility can boast almost 70 years of high-quality production output.
Alongside high-performance bearing technology, Agri Disc hubs are equipped with a highly effective sealing system for robust protection against extreme condition applications. This comprehensive system is a combination of labyrinth and contact seal designs, which serves to prevent both the ingress of contaminants and the escape of grease. ‘Greased for life’ Agri Disc Hub bearings provide users with maintenance-free operation.

The innovative design of the bearings and sealing system significantly increases service life. Even under extreme stress, Agri Disc Hub bearings – and thus the implement which they serve – grant a service life that is several times beyond that of other commercially available solutions, while their modularity means they can be adapted very quickly to individual user requirements. In such instances, flexible manufacturing at the Munderkingen plant ensures rapid deliveries at competitive costs, even more so for custom requests.

Question 1:How to choose grease?

Lubrication has a very important effect on the operation and life of INA bearings. Here is a brief introduction to the general principles of grease selection. Lubricating grease is made of base oil, thickener and additives. The performance of different types and different types of lubricating grease of the same type is very different. The allowable rotation limit is different. Please pay attention when choosing. The performance of the grease is mainly determined by the base oil. Generally, low viscosity base oil is suitable for low temperature and high speed, and high viscosity is suitable for high temperature and high load. Thickener is also related to lubricating performance. The water resistance of the thickener determines the water resistance of the grease. In principle, greases of different brands cannot be mixed, and even greases of the same thickener can have bad effects on each other due to different additives.

Question 2:Must the bearings be cleaned before installation? 　

The bearing surface is coated with anti-rust oil, you must carefully clean with clean gasoline or kerosene, and then apply clean high-quality or high-speed high-temperature lubricating grease before installation and use. The effect of cleanliness on rolling bearing life and vibration noise is very large. But we have to remind you in particular that the fully enclosed bearings do not need to be cleaned and refueled.

Question 3:How to install and disassemble?

Do not directly hammer the INA bearing end face and non-stressed surface during installation. Use a pressure block, sleeve or other installation tools (tooling) to make the bearing evenly stressed, and do not install it through the driving force of the rolling element. If the installation surface is coated with lubricating oil, the installation will be smoother. If the interference is large, the bearing should be placed in mineral oil and heated to 80~90℃ as soon as possible. The oil temperature should be strictly controlled not to exceed 100℃ to prevent the tempering effect from reducing the hardness and affecting the size recovery. When it is difficult to disassemble, it is recommended that you use the disassembly tool to pull out and carefully spray hot oil on the inner ring. The heat will expand the inner ring of the rolling bearing, making it easier to fall off.
