For radial and axial loads in both directions, the TIMKEN MB series deep groove ball bearing belongs to the 6000 family. Its machined bronze cage, ball-centered, suits demanding duty. Typical uses include electric motors, pumps, and gearboxes. MR Industrial Accessories supplies this line to customers across the US, Canada, Mexico, and South America.
Reading the part number is straightforward. The first digits identify the 60 series size: for example, 6015MB has a 75 mm bore, while 6040MB has a 200 mm bore. The MB suffix tells you the cage is machined bronze, ball-centered. That cage handles high temperatures and vibration better than a stamped steel cage. Always confirm the full designation before ordering a replacement.
These bearings turn up in large electric motors, centrifugal pumps, industrial fans, and gearboxes, as well as in mining equipment, cement plants, and water treatment plants. Running at high speeds while taking combined loads makes them a flexible choice. Our team can help you match the right variant to the application.
Selection depends on radial and axial load, rotational speed, and the surrounding conditions. Choose the MB bronze cage when temperatures are high or dynamic stresses are significant. Verify alignment between shaft and housing, and apply the correct lubricant: grease for slow-running applications, oil where heat must be dissipated. Proper fitting at mounting avoids early failures and keeps service life on track.
Bearings in the 6000 series with the MB suffix can be interchanged with equivalent products from other makers that use the same dimensional nomenclature. For a quote, provide the complete part number and, when possible, the main dimensions. We can advise on compatibility. Cage type matters: the bronze version brings advantages in severe service.

- TIMKEN 6330MB measures 150 mm across the bore and 320 mm across the outside diameter; its width is 65 mm (150 x 320 x 65 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6330.
- What does the MB suffix mean on a TIMKEN bearing?
- It means the bearing has a machined bronze cage, ball-centered. This cage resists high temperatures and vibratory loads better than stamped steel cages, so it is recommended for demanding applications.
- How do I choose the right 6000 series bearing?
- You need the shaft diameter, radial and axial load, and operating speed. The complete part number, such as 6015MB, defines the size. If you have doubts, send the data by WhatsApp or email and we will advise you.
- Can I replace a bearing from another brand with a TIMKEN MB?
- Yes, if the dimensions and cage type match. The 6000 series is standard among manufacturers. When requesting a quote, send the original part number and we will indicate the TIMKEN equivalent and help with interchangeability.
