bearings

OKB is continuing to introduce advanced management models and optimization of vertical integration system. We would like to provide you the best solution with high flexibility, huge inventory, the quality bearings and the shortest delivery time.

Precision Bearings: OKB mainly operates in high-performance bearings, Special Bearings and High-speed Spindle Bearings from 1mm inner diameter to 6800mm outer diameter.

Ceramic bearings are divided into fully ceramic bearings and hybrid ceramic ball bearing. The material is zirconium oxide (ZrO2) and silicon nitride (Si3N4), with anti-magnetic, insulated, strong acid-resistant, strong alkali-resistant, cold-resistant, oil-free lubrication and so on. Our company has a wealth of experience especially in the level-P4 and level-P5 of high precision ceramic ball bearings. Our professional production technology assured you that the bearings used in high-precision instruments, special and extreme working conditions.

The inner diameter of large and extra large size bearings is φ 200mm~ 4500mm, including table bearings/slewing bearings, rolling mill bearings, non-standard precision bearings, to meet the requirements of different types, sizes, grades and special usage. Strict internal control standards and integrated test ensure the quality of each bearing meets or exceeds the national standards.

Miniature Bearings involve more than 2200 specification or more than 5000 varieties from 1mm inner diameter to 200mm outer diameter. These bearings are low noise, low vibration, high precision, high speed, high temperature resistant and perfect sealing. That can be widely used in micro-motor, micro-step motor, fitness equipment, motors, household fans, precision instruments, machinery equipment, toys, medical equipment and other fields.

Bearing block including spherical outside surface bearing, sliding bearing (unit), adapter sleeve, all kinds of non-standard bearings and housings, etc. All products are processed by CNC machining equipment with strong technical force, excellent processing equipment and complete test equipment.

Our company agents SKF, NSK bearing grease. The grease can effectively avoid unexpected downtime and extend maintenance intervals. Also it greatly enhance the reliability and durability of bearings. That enables customers to maximize use of the bearing.
All products passed ISO9001 quality management system certification, ensure your 100% satisfaction. Our goal is to make all our customers satisfied with our products.
