What are the dimensions of this SKF ball bearing?

The bearing has a 35 mm bore diameter, an 80 mm outside diameter, and a width of 21 mm.

What is the purpose of the tapered bore on the SKF 1307 EKTN9?

The 1:12 tapered bore allows easy mounting directly onto tapered shaft seats or with an adapter sleeve.

What is the advantage of a self-aligning ball bearing?

It accommodates static and dynamic angular misalignment or shaft deflection without increasing friction.

What material is the cage made from?

It features a glass-fibre reinforced polyamide cage (TN9) for reduced weight and smooth, quiet operation.

Does this bearing have integrated seals?

No, this is an open bearing without built-in seals, designed for external oil or grease lubrication.

Reliable alignment for 1307 EKTN9

Practical benefits

Automatic compensation for angular misalignment: You accommodate shaft deflections and alignment errors smoothly thanks to the double-row self-aligning design.
Simple mounting with tapered bore: You install the bearing quickly and securely on plain shafts using a matching adapter sleeve.
Low friction at high speeds: The durable polymer cage reduces running friction and heat buildup, keeping your machinery running smoothly and efficiently.

In a nutshell

The right choise for

With the Skf 1307 EKTN9 double-row self-aligning ball bearing, you prevent premature wear caused by shaft deflection and alignment errors in your machinery. The self-aligning design smoothly accommodates both static and dynamic angular misalignment without generating extra friction or heat. Its tapered bore enables quick, secure mounting onto shafts using an adapter sleeve. Featuring a lightweight, durable polymer cage (TN9), this open bearing delivers smooth, quiet operation at high speeds across drive shafts, industrial fans, conveyor systems, and processing equipment.

Product description

Self-aligning ball bearings, with a tapered bore, have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. The tapered bore facilitates ease of mounting via adapter sleeves or withdrawal sleeves.
