SKF Self-Aligning Ball Bearing 17 mm Inside Diameter 40 mm Outside Diameter 12 mm Race Width Non-Metallic Cage 1203 ETN9

SKF 1203 ETN9 is a precision-engineered self-aligning ball bearing designed for industrial and mechanical applications requiring reliable performance under varying shaft alignments. With a 17 mm inside diameter, 40 mm outside diameter, and 12 mm race width, this bearing features a double row of steel balls allowing higher load capacity compared to single-row bearings. The non-metallic cage made from polyamide (PA) reinforced with fibreglass maintains radial spacing and provides increased strength and durability.

The parallel bore facilitates direct mounting on shafts without the need for adapter sleeves, making installation straightforward. This bearing supports high limiting speeds up to 24000 rpm, suited for applications demanding high-speed rotation with low friction and minimal heat generation. Its design enables effective handling of radial loads as well as smaller axial loads which are typical in machinery with shaft deformation or misalignment.

Constructed with corrosion-resistant steel and an open-end for easy lubrication maintenance, the 1203 ETN9 bears an internal clearance of CN, ensuring optimal performance with minimal play. It complies with no specific external approvals but aligns with SKF’s 2 Light series, indicating a lighter bearing type suitable for moderate operating conditions.

Common industrial applications include centrifugal separators, cereal mills, and ring-spinning machines for yarn production where durable and reliable bearing performance is critical.

Double row bearings provide enhanced load capacity. Reinforced non-metallic cage offers improved durability. High limiting speed supports efficient high-speed operation. Corrosion-resistant materials for extended service life.

Suitable for industrial machinery with shaft misalignment. Ease of maintenance with open-end design for lubrication. Manufactured under strict quality control in Switzerland.
