BEARINGS AND UNITS FOR AGRICULTURE INDUSTRY

LKMZ J.Sir YKRM-IHCKAJl AMTEflHASl ■ UPEC is one of the leading CIS manufacturers of bearings, electric motors, pumps, CNC grinding machines, transmissions and chassis, air-cycle climate control systems, trailed agricultural machinery as well as other machines, equipment, units and components for railway, automotive, agricultural, power and electric machinery, defense, metallurgical and other industries. UPEC was established in 1995 and today it unites a number of leading manufacturing companies and engineering centres with more than half a century of history. The main manufacturing...

The Joint Engineering Centre The main company’s know-how is created in the Joint Engineering Centre of the company, which also includes a number of specialized engineering centres and departments. The Joint Engineering Centre (JEC) was established to implement a new strategy of the UPEC Industrial Group, focusing on the priority of engineering knowledge, development and manufacture of innovative products with a high intellectual level. The JEC performs the most complex calculations and studies, mathematical simulation and optimal design for all of the Industrial Group’s product areas,...

X-SHIELD — multi-lip seals of increased tightness Every agrarian needs bearings for agricultural machinery, which would increase the average time of failure-free operation, minimize expensive down time and maintenance time, as well as reduce production losses. In order to fulfill these requirements, HARP manufactures agricultural bearings with special X-SHIELD seals of increased tightness. Kharkov Bearing Plant (HARP) has developed a brand new line of seals with the new X-SHIELD sealing systems for HARP AGRO bearings for agricultural machinery. The line includes the existing seals with K10...

% 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 2-4,5 times higher than with standard sealing # Extended range of the seal operating temperatures: from -40 to +150°C (HNBR) "rotation rate is specified for bearings of the dimension group 210 acc. to GOST (DIN 6210) and operation mode S1

Technical features and advantages of the X-SHIELD multi-lip seals Wear-resistant and reliable material X-SHIELD seals are made of butadiene-acrylonitrile rubber (NBR), which has a much better wear resistance than conventional nitrile rubber, so the seals serve much longer. This universal material has a good resistance to the most of mineral oils and mineral-based plastic lubricants; gasoline, diesel fuel and fuel oil; animal and vegetable oils, fats; hot water. Operating temperature range is from -40˚ to +100˚С and for a short time up to + 120˚C, and short-term dry friction of the seal lip...

Single Row Deep Groove Ball Bearings with Spherical Mounting Surface of the Outer Ring and X-SHIELD Sealings on Adapter Sleeve Bearing designation

Bearing units with different housings Sealed (maintenance-free) bearing solutions Bearing unit is an assembly component, which combines bearing and bearing housing, and consists of the following components: housing made of cast iron or special materials. It can consist of two or more parts with two or more mounting bolt holes; one or several bearings which are mounted directly on the shaft or attached by means of an adapter sleeve; sealing system X-SHIELD® for bearings protection during operation; fitting for the bearings regreasing during operation. Bearing units can operate at increased...

Advantages of the HARP bearing units Self-alignment of the bearing outer diameter and housing inner diameter. The bearing outer diameter has a spherical ground surface matching to the spherical housing inner diameter, which provides self-alignment between the contact surfaces and compensation of the unit misalignment. Increased service life of the bearing unit. Bearing units are used in severe operation conditions with dust, dirt and moisture penetration and high temperatures. Under these operation conditions the bearing grease properties deteriorate in a short period of time. Therefore it...
