Give contaminants the heave-ho with this ring seal from SKF. It fits snugly onto bearings with a cylindrical bore around a 135mm shaft, keeping your mechanical equipment protected from industrial oils, chemicals and fluids. As the seal has a four-lip design that stops lubricants from leaking out, there's less need for maintenance. As it comes in two parts, you can easily install this component on a pre-fitted bearing. Simply place it inside the seal groove on each side of the shaft.

• TPE material is resistant to heat and corrosion for a longer service life
• Light 0.19kg weight means no extra strain on your setup
• Four-lip design reduces friction to give a smooth performance and faster shaft speeds

• Agricultural machinery
• Automated assembly lines
• Automotive manufacturing

This seal can be used with plummer (or pillow) blocks, which are ball-bearing units that have an insert bearing mounted inside a housing. This housing can be bolted to a surface to keep it stable. Plummer blocks are useful in applications such as conveyor belts and industrial automation because they can handle large loads.
