Seventh bearing plant

was established by decree No. 187 of the Soviet People's Commissariat in 1938 as an enterprise for the repair of roller bearings.

In 1947 on April 28, the Seventh state bearing plant was founded at the industrial base of the repair plant. Its main purpose was to supply roller bearings for oil industry equipment manufactured by mmachine-building plants.
Since 2019 TM "GPZ-7®" has been part of the international financial and industrial group specializing in components for mechanical engineering and heavy industry. Now we offer high quality products, which is achieved by constant monitoring of technological processes, of main components and raw materials. Our quality management system complies with the ISO 9001 and ISO 14001 standards.

Quality control

for all stages of production ensures the required high quality of products. All specifications for GPZ-7® bearings is comply with GOST 520 and ISO standards. Our quality management system complies with the ISO 9001 and ISO 14001 standards.

Rockwell Testing

The Rockwell test determines the hardness of the material by measuring the depth of penetration of an indenter under load.

Vibration testing

and measuring of audible peaks of a rotating bearing can identify and indicate a range of bearing defects, such as imbalance, misalignment, faults to the raceways or possible grease pollution. This ensures our customers consistent quality in every bearing we manufacture.

Radial clearance
Tolerance testing

The radial clearance and inner/outer tolerance test is very important to the operation of the bearing. Each batch of bearings is subjected to a thorough examination by our specialists.
