Winter is the ideal time to maintain your agricultural machinery. Machines are typically not in active use, so there is plenty of time to give them a thorough check and replace worn parts such as bearings. Find out about NTN solutions specifically developed for agricultural machinery!
By replacing bearings now, you can avoid forced downtime at the start of the season due to sudden failure, which can cause serious delays in work.
Soil working – Durable bearings for extreme environments
During soil preparation, machines turn up large amounts of dust and dirt. For this work, NTN offers AGR sealed bearings that can withstand extremely polluted environments. AGR bearings feature a zinc-coated shield plate alongside the L3 3 lip special seal, which prevents dirt from entering the bearing, ensuring a longer bearing life.
Types:
- UC…AGR series (tightened by grub screws)
- EX…AGR series (tightened by an eccentric locking collar)
AGRI HUB – The solution for the toughest agricultural conditions
The AGRI HUB is a pre-mounted, robust bearing unit specifically designed for tillage implements. The design of the AGRI HUB ensures long life, quick installation and minimal maintenance as dirt ingress is prevented by an eight lip seal. In addition, the thick, rugged hub resists shock and impact. Recommended for soil cultivators and seed drills.
Class P6X – The key to easy installation
NTN’s P6X reduced tolerance tapered roller bearings allow for faster and more accurate installation. This results in less dimensional variation in bearings. Furthermore, there is greater stability in axial bearing alignment for optimum machine performance over the long term.
Seeding – Precision and reliability
The main function of the bearings in a seeder is to guide the sowing discs accurately while withstanding extreme environmental conditions. NTN’s 204XAGR bearing is particularly suited to this task, as it is a 4-point angular contact ball bearing, ensuring precision and long life with low maintenance requirements.
If a double row bearing is required, the LLU ball bearing with environmentally friendly sealing is the solution, which also offers protection against contamination.
Hay making – Speed and durability
During harvesting and silage making, bearings are subjected to extreme stress due to the high speed rotating motion. NTN’s GB double row and AB single row ball bearings operate reliably at high speeds while resisting mud, grass and other contaminants.
Baling – Reliable operation over long shifts
Balers are designed for continuous and intensive work. NTN hexagonal bore bearings are specially optimized for baler shafts. The 3 types of special seals prevent the ingress of dirt, thus guaranteeing a long service life. Available in 3 different types.
Harvesting – Designed for intensive use
For harvesters, continuous and reliable bearing operation is essential. NTN has developed 3 seals for this job, all available in UC series tightened with grub screws and 2 possible rotation directions, and EX series tightened by an eccentric locking collar, providing 1 possible rotation direction.
- UC and EX series bearings with L3 seals are specifically designed for contaminated and humid environments. The seal consists of three lip seals that effectively protect the bearings from mud and moderate moisture.
Types:- UC…L3
- EX…L3
- UC and EX series bearings with L4 labyrinth seals offer even more effective resistance to moisture. The corrosion resistant plate has 2 nitrile rubber seals forming a 3 lip system over a labyrinth seal.
Types:- UC…L4
- EX…L4
- The highest protection is provided by the AGR seal, which is a combination of the L3 seal and a zinc-coated shield. For extremely contaminated environments, this will be the bombproof solution.
Types:- UC…AGR
- EX…AGR
Maintenance – The key to long-lasting operation
Proper lubrication and regular maintenance can significantly extend bearing life. NTN DRIVE BOOSTER’s automatic lubrication system ensures continuous lubrication of bearings, minimizing maintenance time and costs.
The selection of bearings for agricultural machinery must take into account the environmental conditions and loads of the specific operation. NTN bearing solutions are specifically designed to meet these challenges, ensuring long life, minimum maintenance and maximum reliability.
