A bearing for all harvesting seasons

The harvest season is a critical period for all farmers. Most crops need to be harvested within a limited window of time for crop growers to achieve the best results. But with the harvesting equipment often kept idle throughout the year, it is critical to ensure that machinery is ready to roll come harvest season.

From small-scale harvesting equipment to large combine harvesters, bearings are key components in the harvesting machinery. If a farmer discovers close to the harvest season that a critical bearing in his machine requires repair or replacement due to excessive corrosion or seizure, the resulting downtime would be nerve-wracking for the farmer and potentially harmful to crop yield.

As Australia’s largest distributor of bearings and industrial solutions, CBC Australia, in partnership with NTN Australia, supplies the NTN Black Bearings, which are ball bearings specifically designed for agricultural applications.

The ‘black’ in the NTN Black Bearings comes from the black oxide treatment that the bearing components go through in the production process to increase the corrosion resistance, resulting in serviceable life of more than twice the equivalent standard bearings, according to Fabio Rebecchi, NTN Australia’s National Product Manager – Bearing Group.

“The NTN Black Bearings are ideally suited for use in harvesting equipment as well as any other agricultural machinery. The black oxide coating covers all of the bearing surfaces, including the inner and outer rings, which offers excellent corrosion and fretting resistance. This helps avoid the common issue of bearing seizure from corrosion that farmers often face with their harvesting equipment,” says Fabio.

With agricultural environments also prone to high levels of contamination for the bearings, NTN also provides trash guard seals specifically designed to protect the bearings in the NTN Black series from any external contaminants, Fabio explains.

“In harvesting, the products that are being harvested can contaminate the bearings, thereby leading to shorter bearing life. The NTN trash guard seals are uniquely designed with a heavy-duty rubber lip bonded to the seal plate to help protect the bearings from both corrosion and misalignment,” Fabio says.

Additionally, the NTN Black Bearing comes 70 per cent factory-filled with a superior heavy duty grease to provide excellent water resistance and long lubricant life, according to Fabio.

“When testing the bearings at our facility in Japan for dust-proofing, the NTN engineering team found that the bearing’s life could be further enhanced by increasing the filling rate of the grease. The filling rate for this particular bearing is higher than you would normally find in the standard bearings, which adds extra protection to keep the contaminants out of the bearing.”

Another plus point with the NTN Black Bearing, according to Fabio, is that the bearings can replace conventional ball bearings without any modifications required in the equipment’s design. This feature is particularly attractive for original equipment manufacturers (OEMs) looking to retrofit their existing machinery with a superior bearing option, he says.

In Australia, NTN bearings are available exclusively through the national CBC distribution network, a partnership that Fabio says helps deliver the high-end NTN products and engineering services to the Australian OEMs and end-user customers.

“Whether it is OEMs looking to implement the NTN Black Bearing in their own agricultural machinery or farm-owners looking to retrofit their existing machinery, the collaboration is made possible through the CBC field representatives who provide the link between the end-users and the NTN global engineering team. The CBC field engineers are quite adept and their support is also backed by NTN’s global engineering team,” Fabio says.

While the NTN Black Bearing is more expensive than the equivalent standard bearings in the market, Fabio says the additional cost is absolutely justified when considering the potential downtime losses from bearing failure.

“The feedback we have received from our customers is that they are happy to pay the extra cost in exchange for the peace of mind that they get by having a reliable bearing in their harvesting machine. Timing is of essence for harvesting and so making sure that the equipment is ready to go when it’s needed most is the biggest benefit that we can provide with this bearing.”
