Self-Aligning Ball B. SKF 1202 ETN9

The SKF 1202 ETN9 self-aligning ball bearing has a 15 mm bore, an outer diameter of 35 mm and compensates for misalignment with its double-row design.

The 1202 ETN9 self-aligning ball bearing is a double-row rolling bearing made from standard bearing steel (100Cr6) with a cylindrical bore. The design features a common spherical raceway in the outer ring, which automatically compensates for shaft deflection and misalignment. The open bearing has the standard radial clearance and a tolerance class of P0/PN or ABEC 1. It is suitable for an operating temperature range of -30 to +120 degrees.

What is the 1202 ETN9 self-aligning ball bearing suitable for in operation?

Designs with longer shafts or flexible housings tend to develop misalignment between the inner and outer rings during operation. This self-aligning ball bearing accommodates misalignment without causing edge pressures or generating additional residual stresses. This design is used in bearing applications where radial loads are predominant and angular misalignment needs to be compensated for.

What are the advantages of the polyamide cage in the ETN9 variant?

The designation ETN9 refers to a version with a polyamide cage that guides the rolling elements. The material reduces the bearing’s own weight and operates more quietly than solid metal cages. As this is an open design without sealing washers, the lubricant can be selected flexibly to suit the specific application. A clean installation environment prevents contaminants from entering the raceways.
