Curtis Universal Alloy Steel Turn-Key / Ready-To-Use Curtis Joint 

In alloy steel, Curtis Universal has all standard sizes available in stock, ranging from 3/8 inch to 4 inch O.D. with standard bores (one-half of the O.D.), keyways and installed set screws. The 3/8 inch and 1/2 inch joints come with set screws only, while other standard O.D. sizes include keyways. Joints 7/8 inch or larger have Curtis` simple Take Apart feature to allow for more specialized modification. Our large inventory allows O.E.M.`s and users delivery on demand.

Universal Applications

• Tractor Steering
• Commercial Ovens
• Bowling Alley Cleaning
• Missile Containers
• Snow Blowers

Curtis Alloy Steel Joints feature 41L40-grade steel for all forks. Forks of 7/8 inch diameter and larger have induction-hardened bearing areas for strength and durability. The body (hubs) of the joints remain in an annealed state, which affords free machinability. Center blocks and pins are machined from 86L20 alloy steel. Center-blocks and pins are carburized and case hardened to generate superior wear characteristics yet remain ductile, thereby enabling the joint to handle shock loads without experiencing premature failure. Universal joint hub modifications are available in metric, which include but may not be limited to bores, keyways, set screw holes, square holes and hex holes. 

Curtis Universal Block and Pin Type Standard Double Joint - Alloy Steel 
 
Curtis double joints are available in 14 sizes, and share all of the advantages of Curtis single U-joints. Features include:

• Extra angularity allows standard units to operate at angles up to 70°.
• Quick and easy TakeApart™ design for easy and economical disassembly and reassembly, with no special tooling required.
• Firm, positive lockup of the entire assembly thanks to Curtis’exclusive Tell-Tale Lock Ring.
• Built-in lubrication passages with Curtis’ exclusive internal lubrication system.
• Lubrication covers (boots) available in all sizes to retain lubrication and keep out contaminants, extending the life of the joint. Curtis Joints do not require grooves on hubs to retain boots.
• Less galling and seizing because Curtis uses dissimilar materials on all bearing surfaces.
• Maximum wear and strength from Curtis’ induction hardened forks.
• Easy machinability due to Curtis’soft hubs.
• Smooth operations and longer life assured by close and well-controlled tolerances between mating parts and Curtis’built-in lubrication system.
• Perfect concentricity with hubs ground on center and centering holes provided on solid hubs to aid in machining.
• Universal joint hub modifications are available in metric, which include but may not be limited to bores, keyways, set screw holes, square holes and hex holes.

Curtis Universal 18-8 Type 303 Stainless Steel, Non-Magnetic Single Joint

Many applications require corrosion resistant universal joints to assure sanitation or to avoid premature oxidation or deterioration. Curtis stainless steel U-joints are particularly important, for example, to industries that use food processing equipment, and for machinery that comes in contact with corrosive chemicals or is exposed to water for long periods. Furnace applications also benefit from stainless steel, which better withstands high temperatures and other environmental extremes.

Curtis offers:

• 14 standard O.D. sizes
• 3/8 inch to 4 inch diameter
• 303 grade stainless steel in stock
• 304, 316 and other grades available by special order
• Universal joint hub modifications are available in metric, which include but may not be limited to bores, keyways, set screw holes, square holes and hex holes.

Universal Applications

• Boiler Damper Controls
• Bottle Capping
• Surgical Tables
• Submarine Periscopes
• Paper Making Equip.
