230 series spherical roller bearings are designed for applications that require high radial load capacity while maintaining a relatively narrow cross-section. Their compact radial dimensions make them suitable for heavy-duty machinery where installation space is limited but the bearing must still support substantial loads.
JYHY manufactures 230 series spherical roller bearings in a wide range of sizes, from standard 100 mm bore models such as 23020 to extra-large bore bearings with bore diameters exceeding 1,000 mm. The range also includes straight bore, tapered bore and split 230SM designs for different installation and maintenance requirements.

What Are 230 Series Spherical Roller Bearings?
The 230 series is a narrow-section spherical roller bearing series. Compared with larger-section spherical roller bearing series, the 230 series provides a relatively small radial cross-section while retaining substantial radial load capacity.
The spherical roller design also allows the bearing to accommodate misalignment between the shaft and housing. This characteristic is useful in industrial equipment where shaft deflection, housing deformation or mounting conditions can result in angular misalignment during operation.
The JYHY 230 series range includes standard sizes as well as large-bore and extra-large models. Current listed sizes range from 23020 with a 100 mm bore to 230/1250 with a 1,250 mm bore.
230 Series Bearing Size Range
The standard 230 series includes many large-bore spherical roller bearings for industrial equipment. Representative dimensions include:
| Bearing | Bore d (mm) | Outside Diameter D (mm) | Width B (mm) |
|---|---|---|---|
| 23020 | 100 | 150 | 37 |
| 23040 | 200 | 310 | 82 |
| 23060 | 300 | 460 | 118 |
| 23080 | 400 | 600 | 148 |
| 230/500 | 500 | 720 | 167 |
| 230/630 | 630 | 920 | 212 |
| 230/800 | 800 | 1150 | 258 |
| 230/1000 | 1000 | 1420 | 308 |
| 230/1250 | 1250 | 1750 | 375 |
These examples show the broad size range available within the 230 series. For applications requiring a specific dimension outside the listed standard models, JYHY can also evaluate non-standard bearing designs based on customer drawings and dimensional requirements.
230 Series Bearing Bore Designs
Different shaft and installation conditions require different bore configurations. The JYHY 230 series includes straight bore, tapered bore and split bearing designs.
1. Straight Bore 230 Series Bearings
Standard straight bore bearings are suitable when the bearing is mounted directly onto a cylindrical shaft. They are available in a wide range of large-bore sizes and cage configurations.
Examples include 23020CA/W33, 23040CA/W33 and 23060CA/W33.
2. Tapered Bore 230K Series
Tapered bore versions are identified by the K designation. The tapered bore can be used with suitable mounting arrangements where controlled radial internal clearance and installation adjustment are required.
For larger bearings, tapered bore configurations can also be useful when direct mounting and dismounting on the shaft would otherwise be difficult.
3. Split 230SM Spherical Roller Bearings
The 230SM series uses a split bearing design. This configuration is particularly useful where removing the shaft or dismantling surrounding equipment is difficult.
For example, the current product range includes 230SM420MA with a 420 mm bore and 230SM500MA with a 500 mm bore.
Split construction can simplify bearing replacement and maintenance in equipment where conventional bearing removal would require significant disassembly.
CA, MB and CC Cage Options
The 230 series is available with different cage configurations depending on the bearing model and application requirements.
CA Cage
CA versions use a solid brass cage design. Examples in the product range include 23020CA/W33, 23024CA/W33 and 23040CA/W33.
CA bearings can be considered for heavy-duty industrial applications where a robust cage design is required.
MB Cage
MB versions use a machined brass cage. They are available across many of the larger 230 series sizes, including models such as 23048MB/W33, 23060MB/W33 and 230/600MB/W33.
CC Cage
CC versions use a stamped steel cage and are available in a number of standard 230 series sizes. For example, 23020CC/W33, 23024CC/W33 and 23040CC/W33 are included in the current range.
The appropriate cage configuration should be selected according to the operating conditions, load, speed, lubrication and equipment requirements rather than by bearing size alone.
What Does W33 Mean on a 230 Series Bearing?
Many JYHY 230 series bearings are available with a W33 designation. W33 indicates a lubrication groove and lubrication holes in the outer ring, allowing grease to be supplied through the bearing housing without requiring a separate lubrication arrangement around the bearing circumference.
This configuration is useful for industrial machinery operating continuously or under heavy loads where regular relubrication is important.
For example, the product range includes 23020CA/W33, 23040MB/W33, 230/530CA/W33 and many other W33 configurations.
Applications of 230 Series Spherical Roller Bearings
The combination of narrow radial dimensions, high radial load capacity and self-aligning capability makes the 230 series suitable for a variety of industrial applications.
Paper Mill Dryer Rolls
Paper-making equipment often has limited bearing housing space while requiring reliable operation under continuous loads. The narrow section of the 230 series can be advantageous in compact dryer-roll arrangements.
Where maintenance access is restricted, split 230SM spherical roller bearings can provide an alternative installation and replacement solution.
Typical examples include 230SM420MA and 230SM500MA.
Compact Industrial Reducers
Industrial gearboxes and reducers may require bearings that provide high radial load capacity without occupying excessive internal space. The narrow cross-section of the 230 series can help accommodate these space constraints.
Representative models include 23020CA/W33 and 23028CA/W33.
Mining and Cement Equipment
Large mining and cement equipment can require spherical roller bearings with very large shaft diameters and high load capacity. The 230 series extends into extra-large bore sizes such as 230/500, 230/630, 230/800, 230/1000 and 230/1250.
For example, 230/530CA/W33 has a 530 mm bore, while 230/600CA/W33 has a 600 mm bore.
For very large equipment, JYHY also accepts dimensional requirements and non-standard drawings for customized bearing production.
How to Select a 230 Series Spherical Roller Bearing
When selecting a 230 series spherical roller bearing, several parameters should be considered together.
- Shaft diameter: Select the bearing bore according to the shaft and required mounting arrangement.
- Housing space: Check the outside diameter and bearing width against the available housing dimensions.
- Bore type: Choose straight bore, tapered bore or split construction according to the installation and maintenance requirements.
- Cage design: Consider CA, MB or CC cage configurations according to the operating conditions.
- Lubrication: W33 versions provide an outer-ring lubrication groove and holes for grease supply.
- Load conditions: Verify the required radial and axial load capacity for the actual operating conditions.
- Speed: Bearing speed, lubrication, clearance and operating temperature should be considered when the equipment operates at higher rotational speeds.
- Installation and maintenance: Split 230SM bearings may be considered where shaft removal or equipment disassembly is difficult.
- Non-standard dimensions: If the required size is not available as a standard model, provide the drawing or dimensional requirements for evaluation.
Extra-Large Bore 230 Series Bearings
One of the notable features of the JYHY 230 series range is the availability of extra-large bore models.
Models with a slash designation, such as 230/500, 230/630, 230/800 and 230/1250, extend the 230 series into very large shaft diameters. The current listed range includes bore sizes from 500 mm up to 1,250 mm.
These large spherical roller bearings are intended for equipment where conventional bearing sizes cannot provide the required shaft diameter and load capacity.
For large machinery with unusual dimensional requirements, JYHY can manufacture bearings according to customer drawings. Providing the shaft diameter, housing dimensions, bearing width and operating conditions can help determine a suitable design.
230 Series vs. Other Spherical Roller Bearing Series
The 230 series is only one of several spherical roller bearing series used in industrial machinery. The main difference between series is their cross-sectional proportions and available dimensional range.
When installation space is limited in the radial direction, the narrow 230 series can be considered. When a different combination of bore diameter, outside diameter, width or load capacity is required, other spherical roller bearing series may provide a more suitable dimensional solution.
For larger industrial applications, JYHY also supplies other spherical roller bearing series, including 240 series spherical roller bearings and 248/249 series large-bore spherical roller bearings.
