All wear parts are heat treated for increased life. The split block design provides a positive lubrication reservoir for long life and low wear. The pins move resistance free within the bushings, while the bushings remained fixed with the yokes. Standard joints produced from high- grade alloy steel for extra durability and each part of the same joint is completely interchangeable. All parts are produced to extremely close tolerances, and fitted exactly to meet the most rigid backlash requirements. The Blue Block design is available in stainless steel, with keyways and with many custom configurations. Protective coverings are also available for use in contaminated atmospheres.

The oil enters through the oil hole in one pin and into the reservoir. As the speed is increased, oil is thrown centrifugally to thoroughly lubricate each pin and bushing.

Unique center block is produced from out own proprietary powdered metal formulation and sintering process. With its own selfcontained oil supply the block not only acts as a carrying member for the cross-pins, but are also as a continuous lubricates bearing block. As a result, the Hex Block Joint lasts longer than other comparable units and is ideal for applications where oiling is required but impractical because of the universal joint location. Maximum operating angle on standard models is 35 degrees. Hex Block Joints can be special ordered for greater angles and other characteristics.

Using the Alves Blue Block design, with modified and special hardened pins, and the highest quality pre-lubricated and sealed needle bearings in the hubs, they are easily repaired on site using the inexpensive special repair kit available from your local distributor, or from Alves direct. They are physically interchangeable with competing units and provide the precision and reliability required for demanding applications requiring speeds to 6,000 rpm and operating angles to 25 degrees. Greater angular operation can be achieved by utilizing a double universal joint. Protects joints from dirt and contaminants. Adds lubrication capacity, quickly and easily replaced in the field. Plastic straps standard. Stainless steel straps available. BOOT NO. U-Joint Std.
