Decoding SKF 7230 BGAM
- 72Series
- Angular contact ball bearings, 72 series. Series differ in outside diameter and width even when the bore is the same.
- 30Bore
- Bore 150 mm (30 × 5).
- BGAMSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
7230 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 7230 BGAM measures 150 mm across the bore and 270 mm across the outside diameter; its width is 45 mm (150 x 270 x 45 mm).

SKF BGAM series angular contact bearings are built for arrangements that combine radial and axial loading. The inclined raceways create an angular contact between the balls and the rings, which gives the bearing high axial capacity in a single direction. Machine tool spindles, pumps and gearboxes are common homes for this design, where stiffness and precision matter. MR supplies this SKF line and can help you match the bearing to your application.
Reading the code helps narrow down the options. The leading number, such as 7224, 7226 or 7230, sets the size and dimensional series. In the BGAM suffix, B generally signals a 40° contact angle, while GAM points to a machined brass cage guided by the balls, along with other design details. Because suffix combinations do not all share the same values, always check the data sheet for the exact dimensions and tolerances of the item you need.
Typical service includes milling machine and lathe main spindles, process centrifugal pumps, screw compressors, speed reducers and power transmission equipment. Since these bearings take axial load in one direction, they suit assemblies where the shaft must be located axially. Textile machinery, cranes and material handling equipment also use them where precision and durability are required.
Selection starts with the magnitude and direction of the loads, the rotation speed and the operating environment. Sealing deserves attention: open versions need external lubrication and are more exposed to contamination, while sealed or shielded versions keep lubricant in and contaminants out. Internal clearance and preload should be set for the application; in paired arrangements, preload raises rigidity but also friction. Shaft-to-housing alignment must be correct to avoid parasitic stresses, and the right grease or oil extends service life and cuts maintenance.
For interchangeability, bearings in the SKF BGAM series can be replaced by other brands that use the same dimensional and suffix designation. Tolerances and load capacities can differ from one maker to another, so verify compatibility before substituting. Contact angle, cage type and internal clearance need to line up for equivalent operation. Since performance is not identical across all brands, compare the technical specifications of each candidate.

Frequently asked questions
- SKF 7230 BGAM bearing: what are its dimensions?
- SKF 7230 BGAM measures 150 mm across the bore and 270 mm across the outside diameter; its width is 45 mm (150 x 270 x 45 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 7230.
- What does the BGAM suffix mean in an SKF bearing?
- The BGAM suffix covers design details such as the 40° contact angle (B) and a machined brass cage guided by the balls (GAM). These affect load capacity and limiting speed. Check the manufacturer's data sheet for the exact values of a given item.
- How do I choose between an open and a sealed angular contact bearing?
- It depends on the environment and how much maintenance you can do. Open bearings allow external lubrication and reach higher speeds, but are more sensitive to contamination. Sealed or shielded bearings retain lubrication and block dust and moisture, which suits aggressive or hard-to-reach locations.
- Can I replace an SKF BGAM bearing with another brand?
- Yes, when the dimensional designation and suffixes match. Still, confirm tolerances, contact angle and load capacity, because these can vary between manufacturers. Compare the technical specifications of both options or ask our technical team.
