Rod end FLURO GALSW 30 – M30x2 male, left-hand, maintenance-free PTFE (uniball)
- Maintenance-free rod end FLURO GALSW 30: M30x2 left-hand male thread, 30 mm bore, load capacity 82.0 kN static / 168.0 kN dynamic, PTFE liner. 1 pc.
FLURO GALSW 30 Rod End – M30x2 Left-Hand Male Thread, 30 mm Bore, Maintenance-Free (PTFE)
FLURO GALSW 30 is a maintenance-free rod end (also referred to as a rose joint, heim joint, spherical rod end, or threaded uniball) featuring an M30x2 left-hand external (male) thread and a 30 mm ball bore diameter. It supports a static load of up to 82.0 kN and a dynamic load of up to 168.0 kN, and thanks to its steel / PTFE sliding contact surface, it requires no lubrication throughout its entire service life.
A left-hand thread is most commonly paired with a right-hand GASW 30 rod end at the opposite end of a linkage rod. This allows the overall length of the rod to be adjusted simply by rotating it, without disconnecting the assembly.
This rod end belongs to the GALSW series (the left-hand threaded counterpart to the GASW series) manufactured by the German company FLURO-Gelenklager GmbH, built to dimension series K in accordance with DIN ISO 12240-4. Designed for operation under dynamic loads, this series excels in motorsport, mechanical engineering, and any application where a joint must compensate for misalignment and operate with zero play.
In size 30, the standard version of the GALSW series features an M30x2 fine-pitch thread (2 mm pitch) rather than a standard M30 thread with a 3.5 mm coarse pitch. Therefore, pay attention to the thread pitch when selecting a nut or an internally threaded rod.

Construction and Materials
Housing (body with threaded shank)
The size 30 housing is forged from C22 quenched and tempered steel and zinc-plated for corrosion protection. In the GALSW series, housings from size 14 upwards are forged, while smaller sizes (up to and including size 12) are machined from free-cutting steel.
Race (bearing liner)
The race is made of free-cutting steel with a bonded PTFE sliding liner. This layer ensures maintenance-free operation of the joint with zero backlash.
Ball (inner ring)
The ball is manufactured from 100Cr6 (AISI 52100) bearing steel – hardened, ground, and polished.
Applications
GALSW series rod ends are used in linkages that transmit axial forces along the rod while accommodating angular misalignment. Typical applications for the M30x2 size include:
- hydraulic and pneumatic cylinders,
- lever systems and linkages in machinery,
- construction, agricultural, and industrial machinery,
- heavy tubular structures, tie rods, and bracing,
- reaction rods in commercial and special-purpose vehicles (subject to load verification).
Selecting a rod end for a specific joint must account for actual operating loads and an appropriate safety factor – this is the responsibility of the design engineer or installer.
Installation Guidelines
- A 30 mm diameter bolt or pin passes through the ball bore.
- Secure the threaded shank using an M30x2 left-hand (fine-pitch) jam nut – a standard M30 nut with a 3.5 mm pitch will not fit.
- The threaded shank should be engaged to a minimum depth of 1.5 times the thread diameter, i.e., at least 45 mm.
- A left-hand thread is tightened counter-clockwise.
- Do not lubricate the rod end – grease and oil degrade the performance of the PTFE liner.
- To utilize the full tilt angle, use conical misalignment spacers on both sides of the ball.
Frequently Asked Questions
What thread does the FLURO GALSW 30 rod end have?
The FLURO GALSW 30 rod end has an M30x2 external (male), fine-pitch, left-hand thread. The thread length is 71 mm.
What bolt size fits the GALSW 30 bore?
The ball bore diameter is 30 mm, so it accommodates a 30 mm diameter bolt or pin.
What load can the FLURO GALSW 30 handle?
The maximum static load rating is 82.0 kN (18434 lbf), and the dynamic load rating is 168.0 kN (37768 lbf).
Does the GALSW 30 rod end require lubrication?
No. The rod end is maintenance-free – the race features a PTFE sliding liner that must not be lubricated. The rod end does not have a grease nipple.
What is the difference between GALSW 30 and GASW 30?
GALSW 30 has a left-hand thread, whereas GASW 30 has a right-hand thread. Using a pair of right-hand and left-hand rod ends on a single linkage rod allows you to adjust its length without disassembly.
What is the tilt angle of the GALSW 30 rod end?
The ball tilts 17° in each direction, for a total of 34°.
What materials is the FLURO GALSW 30 made of?
The housing is forged from C22 quenched and tempered steel and zinc-plated, the race is free-cutting steel with a bonded PTFE layer, and the ball is hardened, ground, and polished 100Cr6 bearing steel.
Is the price for a single piece?
Yes, the price is for 1 piece of the FLURO GALSW 30 rod end.
