Seeder Bearings

Best possible growing conditions are determined not only by an adequately prepared seedbed – Perfectly placed and distributed seeds in a consistent furrow at a determined depth are prerequisites for high yield. Different influencing parameters such as seed type, soil type, and environmental conditions demand different seeding procedures and machinery. The three basic categories include drills, planters and seeders, using mechanical metering system or air pressure differentials to convey or singulate the seeds.

The furrow opening, seed depth control and seed covering is accomplished by disc opener, gauge wheel, press wheel and closing wheel.

Disk opener:
Opens a narrow furrow in the ground where the seed is planted

Gauge wheel:
Determines the depth at which the seed is planted by controlling the depth at which the disc opener operates

Press wheel:
Presses the seed into contact with the soil in the furrow

Closing wheel:

Drags soil over the seed and fills in the furrow

Application Challenges

Disk opener application condition

  • Single disc or double disc arrangements are used to open the furrow
  • Bearings are pressed into the housing which is riveted or screwed to the disc. The disc assembly is bolted to the machine frame
  • High loads are encountered in no-till farming and due to angle of pull
  • Rigid assembly is required for a precise disc mounting which creates a consistent furrow
  • Dusty and sometimes moist environment
Benefits and functional features:

  • Bolt-on performance:

    • HUB assembly is available for ease of mounting
    • Reduced labor cost and eliminate damage due to incorrect assembly

  • Increased productivity and operation life in field due to:

    • Optimized internal geometry
    • High load capacity
    • High contamination feature package with exclusive sealing system

  • Precise furrow opening:

    • Rigid disc
    • Minimized operating internal clearance
    • Optimized internal geometry

Gauge wheel application condition

  • Bearing is assembled in gauge wheel and bolted on machine
  • Dusty and sometimes moist environment
Benefits and functional features:

  • Increased productivity and operation life in field due to:

    • Optimized internal geometry
    • High load capacity
    • High contamination feature package with exclusive sealing system

  • Increased speed to the market

    • PEER bearing solutions are interchangeable with standard gauge wheel bearings

Press wheel and closing wheel application conditions

  • Press and closing wheel perform different functions in the machine but are exposed to similar application conditions; similar bearing solutions are used
  • Dusty and sometimes moist environment
Benefits and functional features:

  • Increased productivity and operation life in field due to:

    • Optimized internal geometry
    • High load capacity
    • High contamination feature package with exclusive sealing system

  • Increased speed to the market

    • PEER offers the industry’s largest range of high performance seeding bearings

Drills

Seeding of multiple rows by row placement of seeds with a common seeder hopper and a volumetric displacement seeding meter for all the seeding rows. The seeding units are each mounted on a main frame and seed delivery is accomplished pneumatically or by free seed fall through individual delivery tubes.

Planters

Seeding of multiple rows by multiple row seeding units, each typically containing a ground engaging tool, depth control components and a singulating meter device for each row. Seeding units are individually mounted on the main frame. The singulating and conveying of seeds from the seed hopper takes place pneumatically or by air pressure differential.

Seeders

Seeding by spreading or dropping the seed on the soil surface without the use of furrow openers or seed covering devices under the use of volumetric seed metering devices. Also a pneumatically conveying of seeds to the ground openers of the seeding tool or to spreaders at the front of the tillage tool might be used.
