SKF Thermoplastic Elastomer Seal, 40 mm ID, 75.5 mm OD, 12.5 mm

Want to keep your bearings running like a well-oiled machine? Prevent pesky contaminants from getting into the working with this ring seal from SKF. It has a four-lip design, which means it generates less friction than a two-lip alternative, so your bearing spins smoothly even in high-speed applications. Made with TPE rubber that's as tough as nails, this seal is resistant to wear and abrasion, so you can rely on it to keep dirt out and grease in. As well as extending your motor's lifespan, the seal reduces the need for maintenance, so it's a smart pick for busy industrial environments.

• Thickness of 12.5mm means it's a heavy-duty barrier that won't crack under pressure

• Material-handling equipment

SKF's three-barrier solution includes a housing, a seal like this one and a bearing. This three-part system combines to block debris and keep your bearings lubricated, so you get reliable performance and a longer service life.
