When it comes to supporting standard doors, choosing the right Pivot Bearing is essential. The DUFIX DX-PB&AL500 Pivot Bearing is a high-performance door hardware solution designed for residential and light commercial use. Known for its durability and smooth operation, this pivot bearing offers a reliable way to support standard-weight doors with a clean, hidden installation.

In this blog, we’ll explore how the DUFIX pivot bearing works, its key benefits, applications, and how to choose between AL500, AL800, and AL1000.

What is the DUFIX DX-PB&AL500 Pivot Bearing?

The DUFIX DX-PB&AL500 is a light-duty pivot bearing system – a door hardware component that allows doors to pivot open and closed from a single point at the top and bottom, rather than using traditional side-mounted hinges.

The system consists of:

• DX-PB – The pivot bearing mechanism (same across AL500/AL800/AL1000)

• AL500 – The lightweight floor-mounted or frame-mounted socket/receiver

What’s the difference across AL500, AL800, and AL1000?
Based on model numbers:

• AL500 – Light duty, suitable for doors up to 40-60kg

• AL800 – Standard duty, suitable for doors up to 80-120kg

• AL1000 – Heavy duty, suitable for doors up to 150-200kg+

The number indicates increasing weight capacity and physical size.

Applications: Where to Use AL500 vs AL800 vs AL1000

Note: For doors under 30kg, standard hinges are usually more cost-effective than any pivot bearing.

How to Choose Between AL500, AL800, and AL1000

Rule of thumb:

• Under 50kg → AL500 is sufficient

• 50-100kg → AL800 recommended

• Over 100kg → AL1000 required

Installation Overview (Professional Recommended)

Pivot bearing installation requires precision – professional installation recommended even for AL500.

Basic process:

1. Calculate door weight to confirm AL500 is appropriate

2. Cut recesses in door top and bottom for pivot pins

3. Install floor-mounted AL500 socket and top frame bracket

4. Align pivot pins with sockets using level

5. Adjust for smooth operation using adjustment screws

6. Test swing and clearance

For AL500: Standard floor usually sufficient (no reinforcement needed).
