Ball Bearing Units for Agricultural Applications
Insert bearings and housings built for farm and agro-processing machinery, including square and hexagonal bore versions that mount straight onto a drawn bar shaft. Sealing is heavier than on general purpose units because the working environment is soil, chaff and spray. SES holds the range as an authorised SKF distributor, covering bore types Round with grubscrew, square, hexagonal; shaft sizes Common metric and inch farm shaft sizes; sealing Triple lip, flinger, cassette options; housing Cast iron, pressed steel, composite, disc harrow specials. Executions include disc harrow units with square bore, units with hexagonal bore, pillow block units for agricultural duty, flanged units for agricultural duty, among others. It is specified most often into disc harrow and cultivator gang shafts and combine harvester straw walker and shaker drives. Every part is genuine SKF through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Ball Bearing Units for Agricultural Applications in the parts of a plant where this particular duty actually occurs. In practice that means disc harrow and cultivator gang shafts, combine harvester straw walker and shaker drives, rice mill huller and polisher shafts, and equally feed mixer and cattle feed conveyor drives, sugarcane and jaggery plant carrier shafts, tea leaf conveyor and sorting machine rollers. What links them is the duty rather than the machine name — bore forms: Round, square and hexagonal. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the SKF range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Shaft is square or hexagonal drawn bar, as on a harrow gang — Use the matching square or hex bore insert. Machining the bar round to take a standard bearing removes the drive feature and the section that carries the load. Machine works in soil or wet crop residue — Take the triple lip or cassette-sealed execution. A single lip seal in a harrow position packs the raceway with grit and the bearing is finished within one season. The machine stands idle through the off-season — Purge the bearings with fresh grease before laying up, not before the next season starts. Grease charged before storage keeps water out during the months it actually matters. Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Buy the season's spares before the season, not during it. Square and hex bore inserts are slow-moving items in most stores and a harrow standing idle in the sowing window costs far more than the bearings on the shelf.
