Frequently Asked Questions

What is the SKF CRWA1 rotary shaft seal used for?

The SKF CRWA1 rotary shaft seal is a dual-lip oil seal with a spring-loaded lip, designed to retain lubricants and exclude contaminants in rotating shaft applications. It is commonly used in industrial gearboxes, pumps, and motors where a metal case for smooth bores and fluoro material provide resistance to high temperatures and chemicals.

What are the specifications of the SKF 7638 rotary shaft seal?

The SKF 7638 rotary shaft seal has an inside diameter of 0.75 in, an outside diameter of 1.752 in, and a width of 0.25 in. It features a CRWA1 seal design with two lips and a spring, made from fluoro material. This inch-system seal is manufactured by SKF and is suitable for smooth bore housings.

Where to buy SKF rotary shaft seals worldwide?

You can source SKF rotary shaft seals, including the CRWA1 model, through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead times on this and other SKF sealing products.

How to install an SKF dual-lip oil seal with a metal case?
