HARP AGRO UNIT

COMPLETE BEARING SOLUTION

HARP AGRO UNIT bearing units are used with discs of various diameters in a wide range of tillage machinery: cultivators and harrows, rippers and sowing complexes and much more.

HARP AGRO UNIT is a solid, maintenance-free (and at the same time repairable) hub bearing unit, specially developed for application in agricultural machines. It is designed for work in harsh conditions and aggressive environment with dust, dirt, moisture, sometimes chemically active fertilizers and protective agents; as well as intensive combined force effects, including significant static loads, temperature deformations, impact loads, and random overloads from obstacles.

HARP AGRO UNIT:

— Increased service life
— Ultra-reliable three-level bearing protection
— Relubrication-free cassette bearing
— Possibility of repair, incl. bearing replacement without housing replacement in a workshop
— Easy installation and dismantling (minimization of downtime)
— Reliable work for a long time


These benefits allow to increase productivity by 150%, reduce costs by 30%, enhance durability and ensure a long-term high-quality work of the unit (confirmed by successful testing in fields).

BENEFITS OF HARP AGRO UNIT:

Increased service life

юниты график.jpgHARP AGRO UNIT ensures over 5 years of reliable and efficient operation at full capacity and does not require any re-lubrication. High-quality lubrication system reduces consumption of lubricants due to unique design of the seals and prevents contamination of the soil during operation.

A number of HARP AGRO UNIT models are equipped with one of the best hub bearings (6-256907АЕК12L19) with a service life of up to 600 000 km!


Three-level protection

HARP AGRO UNIT.jpgThe principle of three-barrier protection is applied in HARP AGRO UNIT:

1st level – Labyrinth cutter – prevents high pressure of the soil to the sealing and protects unit from mechanical damages.

2nd level – Cassette sealing provides reliable protection from moisture and mechanical impurities.

3d level – Lip sealing – integrated in the bearing and enhanced for application in agricultural machines.


Such complex of seals provide reliable protection against any type of contamination: dust, dirt, moisture, snow, fertilizers, grass, stones, etc.


Reliable operation

Due to cold-rolled rings the bearing has increased wear resistance and reliability. The bearing is in the preloaded, which ensures the unit rigidity.


Massive forged HOUSING

Special hardening of steel, developed specially for the HARP AGRO UNIT, significantly increases its wear resistance. In addition, the high-quality of forgings with an optimal metal fibers arrangement provides high strength and durability of the bearing unit under any operating conditions.


EASY INSTALLATION ON ANY TILLAGE UNIT.

The installation of HARP AGRO UNIT can be simply done even in the field. The unit is mounted to disc with several bolts. Due to high quality of the flange steel the thread stays undamaged even after several discs replacements.


POSSIBILITY OF BEARING REPLACEMENT

The bearing in HARP AGRO UNIT can be replaced at any required time without replacement of the housing. At the end of service life, you can replace bearing in a workshop, and the unit can be used again.
