Tri-ply ball bearing arrangements for agriculture
01 October 2019 | Web Article Number: ME201916393
THE agricultural industry presents a very harsh operating environment for bearings, as farmers plant in extremely dusty conditions. In order to prevent premature bearing failure, supplier Bearings International (BI) has designed special agri hub units with tri-ply seal ball bearing arrangements to prevent the ingress of dust and dirt.
According to the company, this feature ensures an extended operating life, which is a critical factor as farmers have a limited planting period. Tri-ply seals are a one-piece design incorporating three seals moulded to a shroud cap. This not only provides protection against contaminants, but prevents the loss of lubricating grease.
BI has five different bearing hub units available for planters that fall under its Agri-Smart banner of value-added products and services for the agricultural sector. All have a fastening kit that can be ordered separately.
BAA0001 has been designed for fertiliser coulters, potato planters, and disc harrows; BAA0003 for 16 mm planter discs; and BAA0004 for furrow openers. The latest agri hub unit, BAA0005, is a completely modular bearing hub that can be used on the planter disc, gauge wheel, and closer wheel by means of adapter shafts.
Installed on planters for testing purposes, the agri hub units have been in operation for the last four years without any failures, the company said. BAA0001 and BAA0003 have been on the market for a few years already and have shown 11% growth in sales year-on-year.
BI Business Development Leader – Agriculture, Gerhard Pienaar said the BAA0005 modular concept was launched at NAMPO 2018, and has been widely-accepted by the farming community. “With the planting season around the corner, we have increased our stock levels, and hope to show some good results before year-end.”
He added that the company’s strategy for the sector was to continue to make inroads with farming cooperatives, to ensure it has the right products at the right place and at the right time. “This often means travelling to remote locations to offer our back-up and support to the farming community.
“As a solutions provider, we listen to our customers’ pain points, and are open to suggestions as to how to solve their problems. To this end, we attend as many agricultural exhibitions around the country as often as possible, so that we can engage with our customers face-to-face,” Pienaar said.
In this regard, the Agri-Smart range has recently been supplemented by Bauer electric motors to offer farmers a complete solution.
The main products supplied are bearings and seals, sprockets and chains, power take-off (PTO) shafts, v-belts and pulleys, electric motors, gearboxes, and couplings. In conjunction with Jonnesway, BI has developed an agri toolbox.
This all-in-one toolbox fits behind a bakkie seat in a robust cushioned case to protect the tools during transit. It allows for 95% of common problems to be repaired in the field.
