PHSB5L Rod End Bearings 5/16″ Bore FOCMKEAS Pre‑Lubricated Set 2 pcs

Description

Product Overview

The PHSB5L rod end bearing from FOCMKEAS is engineered for demanding industrial applications where precision, durability, and ease of maintenance are paramount. Constructed from high‑grade #45 steel, the bearing body undergoes solid forging and heat treatment to achieve a hardened surface that resists wear, corrosion, and impact forces. Inside the spherical joint, a composite material liner provides self‑lubricating properties, eliminating the need for frequent greasing and reducing downtime. The 5/16″ bore size matches standard hydraulic cylinder shafts, while the left‑hand female thread (5/24) ensures compatibility with a wide range of equipment. Each package contains two identical bearings and a jam nut, allowing users to secure the joint quickly and maintain alignment under load.

Key specifications include a static load capacity of 8.4 kN and a dynamic load capacity of 6.9 kN, supporting heavy‑duty operations in forging machines, CNC equipment, and power tools. The design tolerates up to 10° of angular misalignment, providing flexibility in assembly and reducing stress on adjacent components. The pre‑lubricated joint incorporates a unidirectional oil valve that distributes lubricant evenly across the bearing surface, extending service life and ensuring consistent performance even in harsh environments.

Usage

These rod end bearings excel in applications that demand precise motion control and high load-bearing capacity. In hydraulic cylinders, the bearing supports the piston rod, allowing smooth extension and retraction while absorbing shock loads. CNC machines benefit from the self‑aligning feature, which compensates for minor misalignments in linear guides, resulting in higher positional accuracy and reduced wear on guide rails. Power tools such as pneumatic presses and forging equipment rely on the bearing’s ability to handle repetitive high‑force cycles without degradation.

Installation is straightforward: insert the bearing onto the shaft, align the left‑hand female thread with the mating component, and tighten the jam nut to secure the joint. The pre‑lubricated design means that no additional grease is required during assembly, though periodic inspection is recommended to verify that the oil valve remains unobstructed. The bearing’s robust construction makes it suitable for outdoor or dusty environments, as the sealed joint protects internal components from contaminants.

FAQ

What size shaft does the PHSB5L bearing fit?

The bearing is designed for a 5/16″ (0.3125 inch) bore, compatible with standard hydraulic cylinder shafts and many CNC machine components.

Can the bearing be used in high‑temperature environments?

Yes. The forged steel construction and self‑lubricating composite liner can operate effectively up to 150 °C (302 °F) when properly installed.

How often should the bearing be inspected or serviced?

Because the joint is pre‑lubricated, routine inspection every 6‑12 months is sufficient for most applications. Check for signs of wear, ensure the jam nut remains tight, and verify that the oil valve is not blocked.

Is the left‑hand thread compatible with right‑hand components?

The left‑hand female thread is intended for specific assemblies that require opposite rotation direction. It is not interchangeable with right‑hand threads without an adapter.

What is the warranty period for this bearing?

FOCMKEAS offers a one‑year limited warranty covering manufacturing defects, providing peace of mind and confidence in product quality.
