Non-Standard Bearings - Custom Special Size Industrial Bearings

Non-standard bearings are customized industrial bearing products that differ from international standard ISO and standard national dimensions. Unlike regular standard bearings with fixed sizes and structures, non-standard bearings are tailor-made according to special equipment structures, unique installation spaces, special load requirements and extreme working conditions. They are indispensable core components for special mechanical equipment, customized automation machinery, modified industrial devices and special engineering projects.

Standard bearings have fixed parameters including bore diameter, outer diameter, width, clearance and structure, which cannot adapt to all personalized industrial scenarios. Non-standard bearings perfectly solve the problem of size mismatch, structural incompatibility and performance insufficiency of standard bearings. We provide full-series non-standard bearing customization and production services, covering almost all mainstream bearing types in the industry, with complete customized models and reliable industrial performance.

Full Range of Custom Non-Standard Bearing Types & Models

1. Non-Standard Cylindrical Roller Bearings

We customize all series of non-standard cylindrical roller bearings with special inner diameter, outer diameter, width, roller size and special clearance. Covering all conventional cylindrical roller series including NU, N, NJ, NUP, NN, NNU, four-row mill bearings and full-complement bearings. Custom special-size models include non-standard NU200 series, NU300 series, NU400 series, N200 series, NJ200 series, NUP200 series, NN3000 series and special four-row FC series bearings. These customized bearings are widely used for modified gearboxes, special motors, rolling mill auxiliary equipment and heavy-duty customized transmission machinery.

2. Non-Standard Needle Roller Bearings

Custom non-standard needle roller bearings are one of our mainstream customized products, including special Fw size, special outer diameter D, special width B, special roller diameter Dw and special length L1 needle bearings. Covering NK, RNA, NA, NKI, AXK, NTA series non-standard models. Custom types include non-standard stamping outer ring needle bearings, solid ferrule needle bearings, thrust needle bearings and customized needle roller cage assemblies. Suitable for compact installation space, special shaft diameter matching and low-speed heavy-load special mechanical equipment.

3. Non-Standard Deep Groove Ball Bearings

Custom special-size deep groove ball bearings, including unconventional bore diameter, outer diameter and thickness, non-standard double-sided sealing, single-sided sealing and open-type customized ball bearings. Covering 6000, 6200, 6300, 6400 series special modified models, as well as thin-wall non-standard ball bearings and thick-wall reinforced non-standard ball bearings. Widely used in customized automation equipment, special electrical appliances, medical machinery and light industrial modified equipment.

4. Non-Standard Tapered Roller Bearings

Covering 30200, 30300, 32200, 32300 series non-standard modified models, suitable for special reducers, engineering machinery modified parts, special vehicle chassis equipment and heavy-load positioning machinery.

5. Non-Standard Thrust Bearings

Custom non-standard thrust ball bearings and thrust roller bearings, including special outer diameter, inner diameter and thickness thrust bearings, non-standard thrust needle bearings and reinforced heavy-duty thrust bearings. Applicable to special hydraulic equipment, vertical mechanical equipment and customized axial load-bearing devices.

6. Other Custom Special Bearings

In addition to the above mainstream types, we also customize non-standard spherical roller bearings, non-standard angular contact ball bearings, non-standard self-aligning ball bearings and special stainless steel non-standard bearings. All special-sized, special-structured, special-material and special-performance bearings can be customized according to drawings and samples.

Customizable Parameters of Non-Standard Bearings

All non-standard bearings support full-parameter personalized customization. We can adjust and produce according to customer actual needs, including special bore diameter, special outer diameter, special bearing width, special roller diameter and length, special internal clearance, special sealing structure, special retainer type and special chamfer size. Meanwhile, we support performance customization such as high temperature resistance, low temperature resistance, low noise, high speed, heavy load and impact resistance.

In terms of materials, we provide customized high-carbon chromium bearing steel, stainless steel, high-temperature alloy steel and wear-resistant special steel. Cage options include steel cage, brass cage, nylon cage and customized reinforced plastic cage, which can meet the working condition requirements of different industries.
