CARB Toroidal Roller Bearing 2215 KC3

Prices are EX WORKS. Delivery is calculated separately based on freight and local handling.

The CARB Toroidal Roller Bearing 2215 KC3 is a revolutionary self-aligning bearing that combines the best characteristics of spherical, cylindrical, and needle roller bearings. This unique design allows it to accommodate angular misalignment without increased stress levels while providing frictionless axial movement within the bearing.

Advanced Self-Aligning Performance

Engineered for excellence, CARB bearings compensate for the thermal expansion of the shaft, functioning effectively in the non-locating position of self-aligning bearing arrangements. The specialised roller profile is designed to prevent stress peaks at the roller ends, significantly extending the service life of the component compared to standard bearing types.

With a C3 radial internal clearance and a tapered bore (K), this bearing is optimised for high-load levels. Its self-guiding rollers ensure that friction and frictional heat remain at low levels, making it ideal for high-performance industrial applications.

Troubleshoot Bearing Temperatures - Decanter Maintenance

A simple rule for troubleshooting bearing temperatures: No more than 180°F (82°C) on the housing. The bearing outer ring can be up to 20°F (11°C) hotter than the housing.

Trouble Shooting Bearing Temperatures

Preventative Maintenance

A simple rule for troubleshooting bearing temperatures: No more than 180°F (82°C) on the housing. The bearing outer ring can be up to 20°F (11°C) hotter than the housing. The lubricant originally specified for the application was likely selected to run at lower temperatures. A temperature increase of 50°F (28°C) may cause oil viscosity to drop by 50% or more. This could be the "tipping point" for the application, causing it to go from a hot (but stable) condition, to a hotter, unstable condition where thermal runaway occurs. Eventually, it doesn't matter how much lubricant you add to the application: the oil film is too thin inside the bearing to prevent metal-to-metal contact. Friction and heat build up, which could lead to catastrophic machinery seizure.

A better procedure for "hot" bearings would be:
  1. Check the housing surface temperature. It might be OK, even though most people find anything over 130°F (55°C) too hot to touch.
  2. Slowly add the proper amount of fresh grease to the application (use SKF Dialset). If it's a motor or other machine with a grease relief, open the relief and allow excess grease to escape.
  3. Monitor the temperature and make sure it doesn't run away. (You'll often get a temperature spike after adding grease as the bearing ejects the excess into the housing. This might take 30 minutes to several hours to stabilize, depending on the size of the machine.)
  4. If the temperature keeps going up, call for help - you will probably have to shut down and investigate.

Catastrophic failures can have untold consequences. Contact SKF or The Olive Centre, we can help you with temperature issues in bearings. A simple call could save you time, money and perhaps someone's life.

Why the type of bearing is fitted is important to the application?
