For precision equipment that calls for a specific mounting, the SKF RV-… DB special bearing delivers a paired solution. Its code combines an item number with the DB suffix, which signals a two-bearing arrangement. MR Industrial Accessories LLC supplies this line and can help you match the right variant to your application.
The designation follows a simple pattern: RV prefix, item number, DB suffix. RV marks the special series, the number identifies each size, and DB tells you the two bearings are paired in back-to-back configuration. That arrangement gives high rigidity and the ability to handle moments. One example is RV-318564 DB, where 318564 is the size reference. If you need to confirm a code, our team can walk you through the nomenclature.
These bearings appear in sectors where precision and stiffness matter, such as metalworking, machine tool building, food processing and automotive manufacturing. They are often found in milling spindles, grinding heads, rotary tables and inspection equipment. The paired design supports combined loads and helps maintain alignment when conditions are demanding.
When choosing a bearing, consider the arrangement you need (DB, DF, DT), internal clearance, sealing method and lubrication. Mounting requires precise alignment and controlled preload; follow the manufacturer's instructions and use the proper tools. Grease or oil lubrication is possible, depending on speed and operating temperature. Always check that the shaft and housing dimensions match.
SKF RV-… DB series bearings can be interchanged with equivalents from other brands if dimensions, tolerances and arrangement are the same. Compare technical data rather than relying on the code alone. Alternatives are available, but quality and performance can differ. Our technical team can help you evaluate the best option for your equipment.
To request this special bearing, send the full code by WhatsApp or email to MR Industrial Accessories LLC. We will reply promptly with a quote and technical advice, and we can suggest equivalents or help you choose.
