Double Row Self - Aligning

Radial Self-Aligning Ball Bearing

These bearings are designed to accommodate shaft deflection when running and will also cope with initial misalignment. The double row bearing is designed primarily to withstand radial load with a small capacity for axial load. Also available with ring seals (rubbing seals) made from oil-resistant, non-wearing synthetic rubber with steel reinforcement on both sides (Type 2RS1).

Open Bearings

ETN9 and KTN9 are Open self-aligning bearings without a seal available in parallel or Taper bores.

Sealed bearings

2RS1TN9 are sealed (NBR) bearings packed with grease with a lithium thickener suitable for temperatures from -40°C to + 100°C. They are sealed for life, so should not be heated above 80°C before mounting and must not be washed out under any circumstances.

TN suffix denotes polyamide cage

Supplied with

instruction leaflet.

SKF Ball Bearing, 40mm Inside Diameter, 90mm Outside Diameter - 1308 ETN9

How does the self-aligning feature improve functionality?

This feature allows the bearing to adjust to angular misalignment, reducing wear and prolonging the component's lifespan.

What type of lubrication is recommended?

A standard grease or oil that meets high-speed application requirements is advisable for optimal performance and durability.

Is it compatible with other bearing types?

Yes, it can be incorporated with various bearing types in multi-bearing arrangements, providing design flexibility.

Can it handle extreme temperatures?

It functions well under standard conditions, but specific temperature ratings should be adhered to in order to prevent degradation.

How often should maintenance be performed?

Regular inspections every six months are recommended, along with lubrication checks to ensure effective operation.
