HARP bearings for mining and metallurgy

Understanding the problems of mining companies, Kharkov Bearing Plant has been successfully developing and producing bearings for many years that guarantee reliability and safety, resistance to temperatures, and also ensure efficient operation of equipment in an extreme environment.

Impact loads, noise, vibration, misalignment and polluted environment, as well as other factors in which there is a complex process of mining and raising rock to the surface, contribute to the rapid deterioration of equipment, which affects the application of more stringent requirements for it.

General purpose and industrial bearings for the mining and metals production sector can be used both in equipment of mining companies and metal industry of MMPC.

Kharkov Bearing Plant offers a wide range of bearing products for the mining and metals production sector and provides the opportunity to choose solutions for the manufacturer based on its needs.

Thrust ball bearings
They are used in supports with combined loads. Depending on the ratio of radial and axial loads, either a single bearing with an appropriate contact angle, or in the case of the need to increase the support load-bearing capacity - a complete set of several single bearings are used.

Single row radial ball bearings
Designed to work under radial loads. Provide for the perception of minor axial and combined loads. They are produced both with a stamped kite separator and with a massive separator made of polyamide and brass. They have the highest speed characteristics, and can work at high speed.

Radial roller bearings with short cylindrical rollers
Designed mainly for the same purposes as radial single row ball bearings, but are used in units with heavier radial loads. Radial bearings can operate at high speeds.

Double row radial ball bearings
Self-aligning ball bearings. The non-split design of the double row bearing allows for self-aligning within certain limits, without compromising performance when bearing rings are tilted from misalignment of seats or deflection of the shaft from workloads.

— Use of improved steel for ball bearings with a reduced proportion of oxygen content, which reduces fatigue failure.
— Optimized radius of the raceways, allowing to increase the dynamic load capacity of bearings and, accordingly, their durability. 
— Superfinishing surface treatment, which makes it possible to reduce heating of bearings, noise and vibroacoustic characteristics. 
— Massive polyamide separator, increasing the speed characteristics of bearings and minimizing noise and vibration.
