GLOCRORET Universal Steering Shaft 3/4-in-36 Spline to 3/4-in Double-D — 83 mm Black, 40Cr Alloy, Needle Roller Bearings

GLOCRORET's 3/4"-36 spline x 3/4" double-D universal steering shaft is a compact, black-coated U-joint made from 40Cr alloy steel for reliable drivetrain connection in custom and replacement steering applications. This precision universal joint pairs a 3/4"-36 spline input with a 3/4" double-D output and measures 83 mm (3-1/4") overall. Built with premium needle roller bearings and a corrosion-resistant finish, it is designed to handle moderate rotational speeds and working angles while fitting many aftermarket steering columns, grinders, and light industrial linkages.

What are the key mechanical specifications I should know?

The shaft uses a 3/4"-36 spline on one end and a 3/4" double-D on the other, giving a secure, non-slip connection to matched components. Total length is 83 mm, and the unit is finished in a durable black coating to resist corrosion.

• Input: 3/4"-36 spline; Output: 3/4" double-D
• Total length: 83 mm (3-1/4")
• Material: 40Cr alloy steel with corrosion-resistant coating
• Bearing: premium needle roller bearing for smooth rotation

How much rotational speed and angular movement can it handle?

This universal joint is rated for moderate speed and articulation suitable for common steering and light-duty industrial use. Keep operating conditions within the specified limits to ensure long service life and stable performance.

• Maximum rotational/operating speed: 4,000 rpm
• Maximum working angle: 35°
• Best suited for intermittent or continuous use within these parameters

Which applications is this U-joint compatible with?

Its configuration and construction make it versatile for automotive restoration, custom street rods, sand rails, and small machinery. It is commonly used where a compact, sturdy connection is required between steering shafts or power transmission linkages.

• Street rods, hot rods, and custom steering links
• Sand rails, ATVs, and off-road linkages with matching spline/DD sizes
• Grinders, leveling devices, automated lifts, and light industrial equipment

How do I measure splines and confirm fit before buying?

Accurate measurement prevents mismatches: measure the round shaft diameter for double-D shafts and count teeth around the spline for spline shafts. Use calipers for diameter and mark a starting tooth to count splines precisely.

• DD shaft: measure outer diameter of the round portion (ignore flat faces)
• Spline count: mark one tooth, count all teeth until you return to the start
• Confirm mating component specs (3/4"-36 spline and 3/4" DD) before installation

Who is this for? This GLOCRORET universal steering shaft is aimed at mechanics, restorers, and hobbyists who need a compact, durable U-joint to adapt or replace steering and drive linkages. It suits custom car builders, light industrial equipment owners, and anyone retrofitting steering columns who can match the 3/4"-36 spline and 3/4" double-D dimensions. Backed by a 12-month customer service policy, it provides a straightforward, high-strength option when a precise spline-to-DD connection is required.

FAQ

Q: Does this U-joint fit my 3/4" DD steering column?

A: Yes if your column uses a 3/4" double-D profile on the mating end; verify the outer round diameter matches 3/4".

Q: What is the maximum operating speed and angle?

A: Rated for up to 4,000 rpm and a maximum working angle of 35°; stay within these limits for longevity.
