•   These Crosby blocks are what we offer after using Sauerman blocks for years. Now that Sauerman marine blocks are no longer in business, we have searched for a affordable replacement.  Our experience with brass bushed sheaves are, they are maintaince intense with short life in underwater applications. The Sauerman blocks had roller bearings and had very good service life. Drag line blocks also run roller bearings. Don’t be told you cant run this type block. We have used roller bearing blocks underwater for many years with good performance. These are the Crosby blocks we offer.
