Joint Bars 4 Holes for Rail 60E1 | Direct Manufacturer

Joint bars with 4 holes for 60E1 (UIC 60) rail are heavy-duty connectors designed for standard track applications, typically weighing around 17.5 kg to 18.1 kg per piece. While 6-hole variants are often preferred for high-stress heavy haul lines, 4-hole bars are commonly used for standard maintenance or industrial branches.

Technical Specifications

These components are manufactured to match the profile of 60E1 rail, which has a mass of 60.21 kg/m. 

• Length: Standard length is approximately 600 mm to 630 mm.

• Material: Typically high-carbon steel, such as Chinese grade 55# or 50#.

• Hole Configuration: 4 round or oval holes designed to align with standard 60E1 rail drilling.

• Bolting Hardware: Typically used with M24 x 150 mm high-tensile bolts (Grade 8.8).

• Weight Variance: Depending on the specific manufacturer, weights range slightly: round 18.07 kg (for ø26 holes) or 17.47 kg (for ø28 holes).

• Weight Variance:

600 mm / ø28 holes: ~17.47 kg.

630 mm / ø26 holes: ~18.07 kg.

630 mm / ø25 holes: ~18.10 kg.

Applications

• Railways: High-speed lines, heavy freight corridors, metro systems.

• Maintenance: Replacing worn-out or damaged rail ends.

• Construction: Joining new rails during track laying.

Installation Notes

• Clean rail ends and bar surfaces before assembly.

• Align joint bar holes precisely with rail bolt holes.

• Insert rail bolts, tighten to manufacturer torque specification.

• Check rail gauge and vertical alignment after installation.
