The SKF BMB series covers sealed bearing units built for electric motors, where the bearing, its sealing and the fastening arrangement come together as one assembly. They carry the rotor shaft and keep it aligned in the housing under moderate radial and axial loads. Mounting and removal are straightforward, and the sealing keeps contaminants out while holding lubricant in.
Reading the designation helps you pick the right variant. In a reference such as BMB-6202/032S2/UB008A, the 62 series and the 15 mm bore are stated first, followed by the seal and fastening details. S2 denotes double-lip seals; UB008A or UB108A describes how the inner ring is fastened and positioned. The middle figure, 032 or 080, relates to the housing outside diameter or housing dimension. Matching these codes to the motor avoids a wrong fit.
Typical applications are industrial electric motors driving pumps, fans, compressors and conveyors, including food, cement, mining and water treatment plants where motors run continuously around dust or moisture. Refrigeration equipment and machine tools also use them. The sealed design suits particle-laden surroundings when operating conditions are respected.
Selection comes down to sealing and fastening. S2 double-lip seals hold grease in and block contaminants. UB008A or UB108A sets whether the inner ring sits with clearance or interference, which influences precision and service life. When mounting, verify shaft-to-housing alignment and do not strike the seals. Grease is installed at the factory; severe duty may call for replenishment.
SKF BMB bearings can be exchanged with other brands offering equivalent designations, such as FAG, NSK or NTN, provided the main dimensions and sealing type agree. Tolerances and materials can differ between makers, so confirm compatibility before substituting. MR Industrial Accessories supplies SKF as a brand and can help you match an equivalent to your equipment.

Frequently asked questions
- What does the S2 suffix mean on BMB bearings?
- S2 indicates double-lip seals, which improve grease retention and protect against contaminants. It is a common configuration in electric motors running in dusty or humid environments.
- How do I choose between UB008A and UB108A?
- The difference lies in the inner ring fastening. UB008A usually corresponds to a clearance fit, while UB108A has a firmer fit. The choice depends on loads and required precision; consult us with your motor's part number.
- Are they interchangeable with bearings from other brands?
- They can be interchangeable with bearings from brands such as FAG, NSK or NTN if dimensions and sealing type match. Always verify tolerances and internal design, as they can affect performance.
