Our company continues the glorious traditions of the bearing institute which did bearing research, their application, as well as selection of the best bearings manufactured by numerous specialized bearing factories of the Soviet Union including for supply to military complex factories. Presently our company continues bearing design work, as well as outsourcing and selling of high quality bearings for many industries including cement production, paper, mining, petroleum, steel, wind power turbines, and port equipment. Our brand GPZB is a guarantee of high quality bearings.
Our bearings have advantage over others not only due to adoption of own optimized bearing design but also by applying additional control of the full bearing manufacturing process which results in final products that are the best quality in Russia. GPZB mark ensures compliance to the most complicated application requirements for any customers including the military.
A wide range of bearing types, including high precision ball bearings, spherical roller bearings, cylindrical roller bearings, tapered roller bearings, spherical plain bearings, slewing bearings.
GPZB Bearing Application
Metallurgy industry, Petroleum industry, Mining industry, Cement industry, Paper Industry, Wind Power Turbines, Port Equipment and Hoisting devices
Mining industry bearings
Heavy loads. Abrasive dust and dirt. Extreme temperatures and more. Along with regular exposure to the elements and abrasive dust, vibrating screens experience high vibration and heavy loads. Heavy-duty spherical roller bearings are a manufacturing base for mining machines. GPZB spherical roller bearings improved inner structure design can increase dynamic load rating up to 15%, cuts temperatures and double bearing service life.
Metallurgical machinery bearings
In the steel industry, bearings can be found in a vast range of equipment that is used in both upstream and downstream processes. The operational environment for these bearings is unique to steel making, comprising steel dust, water and heat. GPZB bearings for steel-making are high quality multi-row tapered roller bearings, cylindrical roller bearings, thrust bearings and spherical roller bearing. They can bear heavy loads and vibration shock, operational speeds ranging from extremely slow to high, coupled with rapid acceleration and deceleration.
Wind power plant bearings
GPZB offers TRB and CRB for gearboxes, large size SRB for power generators. All the bearings are CNC machines grinded, raceway of rings and rollers are oil stone superfinished to guarantee precision, reduce friction and operating temperature. Optimized design of the bearings increases load capacity and makes bearing service life longer.
Petroleum industry bearings
Petroleum machinery can be divided into oil drilling machinery, oil recovery machinery, oil automotive machinery, oil refining machinery, industrial pumps. They work under very tough conditions with heavy load, higher requirements for equipment parts. GPZB specializes in producing bearings for petroleum and oil ships, and thanks to professional knowledge and technology GPZB bearings have prolonging maintenance cycle, reducing replacement cost.
Drilling machine top drive structure: cylindrical roller bearings, thrust roller bearings.
Mud pump: spherical roller bearings 231**/240**, tapered roller bearings 352***, cylindrical roller bearings.
Main winch: high precision spherical roller bearings, high precision cylindrical roller bearings.
Cement machinery bearings
Cement equipment are one of the most challenging applications for bearings, in the vertical mill and other important equipment, bearings are used under dust, high temperature, low speed, lack of lubrications conditions. In the cement machinery industry, we provided many solutions for cement equipment, in which large SRB are the main structure, this kind of bearings have strong capacity, which can adapt to high load in axial and radial directions.
