The SIZJ Series (internal thread) is a Maintenance Required rod end bearing with an extruded body and imperial specifications. Specifically designed for overseas automated and precision equipment, the rod end body is manufactured using a cold extrusion process, offering high strength, excellent precision, and light weight. It is equipped with left-hand or right-hand imperial threads and adopts a steel/PTFE composite sliding pair, featuring a maintenance-free self-lubricating design. Strictly adhering to imperial size standards, the product features precise thread accuracy and mounting dimensions that perfectly match European and American precision equipment. The compact structure from extrusion is suitable for miniaturized, high-precision, and low-maintenance linkage scenarios in overseas automated equipment, serving as a core accessory for export precision equipment and overseas precision equipment maintenance.

With inch dimension options including SIZJ4 Female Rod End Bearing, SIZJ6 Female Rod End Bearing, SIZJ9 Female Rod End Bearing, SIZJ11 Female Rod End Bearing, SIZJ12 Female Rod End Bearing and SIZJ15 Female Rod End Bearing, this series is widely used in industrial automation, hydraulic systems, agricultural machinery and mechanical control applications.

Core Advantages

The SIZJ Series adopts an internal female thread structure, allowing easy installation with threaded shafts, rods and mechanical components.

The Female Rod End Bearing design provides:

• Compact installation structure

• Reliable mechanical connection

• Multi-directional angular movement

• Easy assembly and replacement

The imperial dimension series makes it suitable for equipment designed according to inch measurement standards.

Oil Lubricated Rod End Bearing for Smooth Operation

The SIZJ Series is designed with an Oil Lubricated Rod End Bearing structure, allowing continuous lubrication between the spherical inner ring and housing.

Advantages include:

• Reduced friction during operation

• Improved wear resistance

• Longer service life

• Stable movement performance

The lubrication design makes this series suitable for applications requiring frequent movement and repeated oscillation.

High Strength Spherical Rod End Structure

The precision spherical contact surface enables the bearing to compensate for angular misalignment between connected components.

Key advantages:

• Smooth rotational movement

• Improved alignment capability

• Reduced mechanical stress

• Reliable load transmission

Sliding Contact Pair:	Steel/PTFE Composite
Rod End Body Material:	Medium Carbon Steel, Environmental Zinc Plated
Rod end body:	Extrusion-formed
Ball:	Bearing Steel, Heat Treatment, Hardness HRC 58-62, Hard Chromium Plated

Tips:
If the thread is left-hand (LH), the letter "L" must be appended to the bearing designation, e.g., SILZJ 15.
The rod end body is manufactured by the extrusion forming process.
