Self-Aligning Ball B. SKF 1201 ETN9

The SKF 1201 ETN9 double-row self-aligning ball bearing automatically compensates for misalignment and features compact mounting dimensions of 12 × 32 × 10 mm.

The SKF 1201 ETN9 self-aligning ball bearing is a double-row rolling bearing made from standard bearing steel (100Cr6) with a common hollow-spherical raceway in the outer ring. This design automatically compensates for angular misalignment and shaft deflection during operation. With an internal diameter of 12 mm, an external diameter of 32 mm and a width of 10 mm, this bearing is suitable for compact installation spaces. Thanks to its open design, the component can be flexibly integrated into existing lubrication systems.

What is the 1201 ETN9 self-aligning ball bearing suitable for?

Its main area of application is in bearing arrangements where misalignment occurs between the housing and the shaft, or where shafts deflect elastically under load. Typical applications are found in general mechanical engineering with smaller shaft diameters of 12 mm. The spherical outer ring raceway guides the two rows of balls reliably, even when misaligned. This effectively reduces edge pressures on the rolling elements.

What are the distinctive features of the polyamide cage in the 1201 ETN9?

The suffix ETN9 refers to a lightweight polyamide cage, which keeps friction within the bearing low and promotes smooth running. This cage type covers an operating temperature range from –30 to +120 degrees. As this is an open bearing without an integrated seal, you should select the appropriate lubricant for your operating environment. For the design, use the standard radial bearing clearance and tolerance class P0/PN or ABEC 1.
