Product Description

The SKF Self-Aligning Ball Bearing 1309 is a metric high-clearance self-aligning ball bearing with a 45 mm bore, 100 mm OD, and 25 mm outer ring width. It features a tapered 1:12 bore and an open design, identified by bearing industry number 1309 and MPN 1309 EKTN9/C3.

Frequently Asked Questions

What is the SKF 1309 self-aligning ball bearing used for?

The SKF 1309 self-aligning ball bearing is designed for applications where shaft misalignment or deflection occurs, such as in fans, conveyors, and agricultural machinery. Its high-clearance C3 internal fit accommodates thermal expansion, while the tapered 1:12 bore allows secure mounting on adapter sleeves.

What are the specifications of the SKF 1309 EKTN9/C3 bearing?

The SKF 1309 EKTN9/C3 is a metric self-aligning ball bearing with a 45 mm bore, 100 mm OD, and 25 mm outer ring width. It features an open design, tapered 1:12 bore, and C3 internal clearance. The bearing industry number is 1309, and the manufacturer part number is 1309 EKTN9/C3.

Where to buy the SKF 1309 bearing worldwide?

3G Electric supplies the SKF 1309 self-aligning ball bearing to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery for international orders. Contact us to source this bearing for your application.

How to install a SKF self-aligning ball bearing with a tapered bore?

For the SKF 1309 with a tapered 1:12 bore, use an adapter sleeve and locknut to mount the bearing onto a cylindrical shaft. Tighten the locknut gradually while checking radial clearance reduction with a feeler gauge. Ensure the bearing is aligned and lubricated per SKF guidelines to prevent overheating.

Used in

Common applications for SKF
Heavy machinery gearboxes — SKF spherical roller bearings (e.g., 24056 CCK30/W33) for high radial load capacity
Electric motor repair — SKF cylindrical roller bearings (e.g., NJ 307 ECP/C3) for free axial expansion
Pump shaft sealing — SKF CRWA1 rotary shaft seals (e.g., 17100) for fluid retention in rotating equipment
Conveyor system maintenance — SKF wear sleeves (e.g., 99274) to protect shafts from seal abrasion
Machine tool spindles — SKF angular contact bearings (e.g., 7413 BGBM) for axial load support in duplex sets
Industrial fan assemblies — SKF spherical roller bearings (e.g., 23044 CC/W33) for misalignment accommodation
