Bearing Housing SNL 515 - Split Plummer Block

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

The SNL 515 is a premier industrial-grade split plummer (pillow) block housing, recognised for its robust design and versatility. Engineered to provide a stable and protected environment for high-performance bearings, this housing is the primary choice for applications requiring ease of maintenance and long service life. Its two-piece cast iron construction allows for simple assembly and inspection of the internal components.

Optimised Lubrication & Sealing

This housing features integrated seal grooves designed to accommodate a variety of sealing solutions, ensuring protection against contaminants while retaining vital lubrication. It includes a 1/8-27 NPSF threaded relubrication hole, allowing for efficient grease maintenance without disassembling the unit. The high-precision bearing seat is machined to a G7 tolerance class, ensuring an ideal fit and reduced vibration during operation.

Technical Support: For assistance with seal selection or compatible bearing inserts for the SNL 515, please reach out via our Contact Page.

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.
