What You Should Know About Disc Harrow Bearing
The first thing we need to explain is what Disking actually is. Disking is an agricultural practice used to prepare soil. Usually, it follows deep or shallow plowing, it also breaks up clods and surface crusts, while plowing cuts, granulates, and inverts the soil. Additionally, it helps reintegrate crop residues. Now, what is the tool that helps disking? It’s Disc harrow bearings! That plays an important role in agricultural industry, particularly for soil cultivation. These bearings help break up soil, chop weeds, and prepare fields for planting in harsh environments. This article delves into the types of disc harrow bearings, their benefits, and how do you replace them.
Disc Harrow Bearing
Just like other bearings, Disc harrow bearings are also specifically designed to handle extreme conditions like heavy loads, dirt, moisture, and high vibration. They are easy to mount and re-grease, ensuring efficient operation of farm machinery. Mostly, these bearings are enclosed within tough, sealed units that protect the internal components from damage, which helps them to reduce maintenance and extend their service life.

Disc Harrow Bearings - Hex Bore
Hex bore disc harrow bearings are intended for use with hexagonal shafts, which are commonly found in certain types of farm machinery. These bearings are well known for their unique ability to handle both axial and radial loads while maintaining a strong grip on the shaft.
Choose Hex bore bearings for applications where high levels of vibration and shock are present, because they provide a stable connection that can withstand the challenges of intensive soil cultivation, reducing the risk of bearing failure in challenging field conditions.
Features of Hex Bore Bearings:
● Superior grip on hexagonal shafts
● Suitable for high-vibration environments
● Durable under heavy loads and shock
As a farming implement, disc harrows break up clods and surface crusts to improve soil granulation and destroy weeds. An assembly of concave cutting blades (disks) mounted on a common shaft forms a gang.
A Guide to Disc Harrows for Soil Preparation
The disc harrow consists of the following parts:
1. Disc harrow frame that holds and supports discs.
2. A circular concave steel blade/Disc?that is used for cutting.
There are the two types of discs:
● Smooth Edge Disc:?They are also called plain edge disc; consists of plain discs used for normal soil conditions
● Notched Edge Disc:?Also called cut-away discs or scalloped edge discs with serrated edges; used for cutting crop residues and weeds.
3. The arbor bolt, also known as the gang bolt, is a long, heavy shaft made of steel that is mounted with discs.
4. Spool?or spacer?component mounted on arbor bolet?to hold discs in place and prevent lateral movement.
5. Bearings, that are necessary for providing rotation of the gang and regulating the thurst.
6. Bumper plates are heavy iron plates located at the ends of each gang to prevent discs from colliding.
7. Scraper cleans the disk concave side, preventing the disk from becoming clogged.
8. Disc gangs, each group consists of 3 to 13 disks mounted on a common arbor bolt with bearings, bumpers, and disc spacers.
9. Weight box?is ?included on the frame to provide additional weight for increasing the penetration of the disc into the soil.
