GLOCRORET 3/4" DD x 3/4" DD U-joint Single Steering Shaft — Black 83 mm, 35° articulation

GLOCRORET 3/4" DD x 3/4" DD single steering shaft universal joint — a compact, black-coated alloy U-joint that delivers up to 35° articulation and 4000 rpm capability in a 83 mm (3-1/4") overall length.

This U-joint is designed for tight steering and driveline linkages where a durable, corrosion-resistant connection is required. Machined from 40Cr alloy steel with precision needle roller bearings and a protective black coating, it pairs two 3/4" direct-drive (DD) couplings into a single universal joint without a spline. The compact 83 mm total length and 35° maximum working angle make it suitable for custom steering shafts, hot rods, sand rails, parking lifts, and various light industrial linkages.

How strong and fast can this U-joint operate?

The GLOCRORET U-joint is built to handle moderate rotational speeds and common steering loads. Rated for a maximum operating speed of 4000 rpm, its 40Cr alloy construction and needle roller bearings provide wear resistance and consistent rotation in demanding use. This is intended for steering and linkages rather than heavy-duty constant velocity drives.

• Maximum rotational/operating speed: 4000 rpm
• Material: 40Cr alloy steel with durable black corrosion-resistant coating
• Bearing type: precision needle roller bearings for smooth movement
• Designed for intermittent steering and light duty drivetrain applications

Will this fit my steering shaft or custom project?

The joint uses 3/4" DD (direct drive) interfaces on both ends and does not include splines. Confirm your shaft ends are 3/4" DD or use compatible adapters. Its 83 mm total length and compact profile make it easy to incorporate into short steering assemblies or where space is limited.

• End size: 3/4" DD x 3/4" DD (no spline)
• Total length: 83 mm (3-1/4") for compact installations
• Max articulation: 35° per joint to accommodate steering angles
• Common uses: street rods, hot rods, sand rails, parking lifts, grinders

How is it protected against corrosion and wear?

GLOCRORET applies a corrosion-resistant black coating over a 40Cr alloy body to slow surface rust and scratches. Internally, premium needle rollers reduce metal-on-metal friction and help extend service life under typical steering or light drivetrain loading. Routine inspection and lubrication where accessible will further prolong reliability.

• Protective black surface finish minimizes corrosion
• Needle roller bearings cut friction and wear
• Alloy 40Cr core for strength and toughness
• Recommended periodic inspection and maintenance

Who is this for? This single steering-shaft universal joint is ideal for builders, restorers, and technicians who need a compact, robust U-joint with direct-drive 3/4" ends. Choose this piece for custom steering columns, hot rod and sand-rail projects, small automated lift linkages, or light industrial linkages that require up to 35° articulation and operation up to 4000 rpm. For any post-purchase question or issue, GLOCRORET provides a 12-month after-sales service and a customer support response within 24 hours.
