DLY PHS5 is a compact female rod end bearing with a 5 mm bore and M5×0.8 internal thread. It connects a threaded rod or linkage to a 5 mm pin while allowing oscillating movement and limited angular misalignment between the connected components.

The PHS5 rod end body is manufactured from C45 steel with a zinc-plated surface. Its spherical inner ring is made from hardened bearing steel with a chromium-plated running surface. A copper alloy seating ring retains the spherical inner ring inside the housing and supports smooth pivoting movement.

Right-hand and left-hand M5×0.8 thread versions are available. The thread direction, quantity and operating requirements should be confirmed when requesting a quotation.

Load rating note: The 5.7 kN value is the basic static load rating C0. It is not the allowable working load of the complete mechanism. The actual working load must account for load direction, shock, vibration, oscillation frequency, mounting condition and the required safety factor.

Product Features

Compact M5 Connection

The M5×0.8 female thread allows the bearing to connect directly to a matching threaded rod in compact linkage assemblies.

Angular Compensation

The spherical inner ring accommodates limited angular displacement where perfect alignment between the pin and linkage cannot be maintained.

Oscillating Movement

The joint supports repeated pivoting and slow oscillating motion in control rods, cylinder ends and mechanical linkages.

Thread Direction Options

Right-hand and left-hand versions can be supplied for linkage arrangements that require convenient length adjustment.

Installation

Use an M5×0.8 mating thread with sufficient engagement length and a suitable locking method.
Confirm whether the assembly requires a right-hand or left-hand thread before ordering.
Install a 5 mm pin or bolt through the inner-ring bore without forcing an oversized fastener into the bearing.
Support the joint so that the primary load passes through the bearing centre rather than creating unnecessary bending at the threaded connection.
Keep the operating angle within the available articulation range and prevent the housing from contacting adjacent parts.
Lubrication condition should be checked periodically according to operating speed, load, contamination and maintenance interval.

Applications

Pneumatic cylinder linkages Compact automation equipment Control rods Packaging machinery Small robotic mechanisms Adjustable mechanical linkages

PHS5 is intended for compact joints requiring a 5 mm pin connection and M5 female thread. For larger pins, higher loads or thicker linkage components, a larger PHS model should be selected after checking both dimensions and operating conditions.

Dimensions and availability should be reconfirmed before bulk ordering, particularly for left-hand thread and non-standard versions.

FAQ

Q: Is PHS5 supplied with a right-hand or left-hand thread?

A: Both thread directions are available. Right-hand thread is commonly supplied, while left-hand thread availability and quantity should be confirmed before ordering.

Q: Does PHS5 use an M5 thread and a 5 mm bore?

A: Yes. The housing has an M5×0.8 female thread, while the spherical inner ring has a 5 mm bore for the mounting pin or bolt.

Q: Can 5.7 kN be used directly as the permitted working load?

A: No. It is the basic static load rating. Permitted working load depends on load direction, impact, vibration, operating frequency, installation and the safety factor required by the mechanism.

Q: Can PHS5 compensate for shaft misalignment?

A: The spherical inner ring can accommodate limited angular misalignment. It cannot compensate for large installation errors or replace correct mechanism alignment.

Q: Is PHS5 suitable for continuous high-speed rotation?

A: PHS5 is primarily intended for oscillating, pivoting and relatively slow rotational movement. Continuous high-speed operation requires separate confirmation of speed, load, lubrication and temperature.

Q: Which information should be included in an enquiry?

A: Please specify PHS5, right-hand or left-hand thread, quantity, operating load, application and any special material, clearance, lubrication or packaging requirements.
