For machinery built to imperial dimensions, the SKF D/W series deep groove ball bearing offers a single-row design that handles moderate radial and axial loads and runs at high speed with minimal upkeep. It is a common choice in pumps, fans, conveyors and process equipment where metric bearings will not fit. MR Industrial Accessories supplies this SKF line and helps you match the exact variant to your application.

The code tells you what you are getting. D/W marks an inch bearing built to imperial dimensions. The R denotes the outer diameter series, and the number after it sets the size. Suffixes carry the rest: Z means a shield on one side, so 2Z means shields on both sides, and P indicates the precision class, such as P6 or P5. Take D/W R3-2Z/P6: an inch bearing, R3 series, two shields, P6 precision. Reading the code this way lets you confirm the features at a glance.

These bearings suit plants running equipment of American or British origin, where inch sizes are standard. You will find them in centrifugal pumps, industrial fans, belt conveyors, machine tools and continuous process lines. Food, chemical, petrochemical and mining operations often need inch bearings to keep imported machinery compatible. MR Industrial Accessories regularly supplies these components to facilities that want reliable spares without altering their equipment.

Selection comes down to sealing and precision. A Z shield keeps out dust and dirt but not liquids; if water or oil is present, a variant with rubber seals is the better choice. The P class affects internal clearance and dimensional tolerance: higher classes like P6 or P5 mean tighter clearance and greater accuracy for high speeds. During mounting, check alignment between shaft and housing and use the lubrication the manufacturer recommends. Forcing a misaligned bearing shortens its service life.

SKF D/W series bearings interchange with other brands that use the same inch designation, including Timken, NSK and NTN, provided dimensions and suffixes match. When replacing, confirm that the full code includes the protection type and precision class, since a variant without a suffix may not be equivalent. If anything is unclear, we can help you interpret the designation and find the right replacement.
