Reference list

Specialists of the Kharkov Bearing Plant, which was initially developed in accordance with agricultural engineering needs, clearly understand the problem of those, who develop agricultural machinery and who use it. HARP AGRO bearings for agricultural equipment

HARP AGRO: constructive types of bearings HARP manufactures a wide range of single-row self-aligning bearings with double-sided seals and wide inner ring, both with spherical and cylindrical surface of outer ring. Applied in tillage, seeding and harvesting machinery of the world leading manufacturers.

High-quality deep-groove ball bearings Improved bearing steel HARP deep-groove ball bearings are made of ultra clean steel with reduced oxygen content level. This improved steel increases bearing service life and reduces fatigue failures. . Optimized transition shoulder Special raceway transition shoulder reduces edge stresses, friction and heat, while improving lubrication and reducing wear, especially in applications with heavy axial loads or misalignment. Improved surface finish HARP deep-groove ball bearings have an optimized surface finish of all contact surfaces to maximize the effect...

Bearings HARP-AGRO with a tightX-SHIELD seal HARP-AGRO bearing with X-SHIELD® sealing Improved work features — 100% bearing tightness and protection against mechanical damage: X-SHIELD allows the bearing to work effectively even in extreme and dusty conditions of agricultural machinery operation and extends its service life.

X-SHIELD — multi-lip seals of increased tightness ■ Bearing units assembled with bearings with new X-SHIELD seals do not require maintenance during the entire period of operation ■ Unique system of multi-lip seals in combination with protective washers ensure 100% tightness of bearings ■ Term of HARP AGRO bearing's safe operation with X-SHIELD sealing is in 24,5 times higherthan with standard sealing ■ Extended range of the seal operating temperatures: from -40 to +150°C (HNBR)

HARP BEARING UNITS

HARP insert bearings Kharkov Bearing Plant manufactures insert bearings of UC-series (analogues of YAR, YET, YEL) and bearing units on their basis (UCF, UCP, UCFL).

HARP BEARING UNITS Advantages of the HARP bearing units: ■ Self-alignment of the bearing outer diameter and housing inner diameter. ■ Increased service life of the bearing unit. ■ Effective sealing X-SHIELD®. ■ Massive cast iron housing. ■ Device which eliminates rotation of the bearing outer ring in the housing. ■ Complete interchangeability of bearing and housing. ■ No special requirements to the shaft mounting surface.

Table of housings and bearings compatibility The housing can be assembled with bearings of other types

HARP AGRO UNIT is used for discs of various diameters in a wide range of tillage machinery: cultivators and harrows, seed drills and other. HARP AGRO UNIT: • Increased service life • Ultra-reliable three-level bearing protection • Cassette bearing, which does not require additional lubrication throughout the life cycle • Possibility of restoration, incl. with bearing replacement without housing replacement in a normal workshop • Quick installation and dismantling (which minimizes downtime of equipment) • Reliable work over a long period of time; Outer cover sheet steel/elastomer Additional...

HARP AGRO UNIT – BEARING UNITS FOR COMPACT DISC HARROWS Easy adjustment and mounting on any tillage equipment. Superreliable bearing three-level protection (labyrinth cutter, cassette sealing, lip sealing). Reliable bearing – bearing does not require additional lubrication for the entire life cycle. In some models of HARP AGRO UNIT there is used one of the best hub bearing with service life of over 6 000 m.h. High-quality greasing. Possibility of unit restoration and bearing replacement.
