Główka cięgła FLURO GALSW 6 – M6 męska, lewa, bezobsługowa PTFE (uniball)
- Maintenance-free rod end FLURO GALSW 6: M6x1 left-hand male thread, 6 mm bore, load capacity 6.0 kN static / 9.3 kN dynamic, PTFE liner. 1 pc.
FLURO GALSW 6 rod end – M6 left-hand male thread, 6 mm bore, maintenance-free (PTFE)
FLURO GALSW 6 is a maintenance-free rod end (also referred to as a rose joint, spherical rod end bearing, or male uniball) with an M6 left-hand male (external) thread and a 6 mm ball bore diameter. It supports a static load rating up to 6.0 kN and a dynamic load rating up to 9.3 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 6 rod end on the opposite end of a tie rod. This allows the overall rod length to be adjusted simply by rotating the rod, without disconnecting the linkage.
This rod end belongs to the GALSW series (the left-hand counterpart of the GASW series) manufactured by the German company FLURO-Gelenklager GmbH, produced in dimension series K in accordance with DIN ISO 12240-4. This series is engineered for operation under dynamic loads, making it ideal for motorsport, mechanical engineering, and any application where a linkage must compensate for misalignment and operate without play.

Construction and materials
Housing (body with threaded shank)
The housing in size 6 is CNC-turned from free-cutting steel and zinc-plated for corrosion protection. In the GALSW series, housings up to and including size 12 are turned from free-cutting steel, while sizes 14 and above are forged from heat-treated steel.
Bearing liner
The bearing liner is made of free-cutting steel with a bonded PTFE sliding layer. This liner ensures maintenance-free operation and zero clearance (play-free performance).
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 allowing angular misalignment. Typical applications for the M6 size include:
- throttle linkages and lightweight control rods,
- position sensor and suspension travel sensor linkages,
- light-load adjustment mechanisms and levers,
- lightweight tie rods and aerodynamic element supports,
- karting and scale modeling,
- joints in automation systems, small actuators, and precision instruments.
Selecting the proper rod end for a specific joint must take into account actual operating loads and the required safety factor – this is the responsibility of the designer or installer.
Installation guidelines
- A 6 mm (M6) bolt or pin passes through the ball bore.
- Secure the threaded shank using an M6 left-hand locknut (jam nut) – a standard right-hand nut will not fit.
- The threaded shank should be screwed in to a depth of at least 1.5 times the thread diameter, i.e. a minimum of 9 mm.
- A left-hand thread is tightened counter-clockwise.
- Do not lubricate the rod end – grease and oils degrade the performance of the PTFE liner.
- To utilize the full misalignment angle, high-misalignment (tapered) spacers should be fitted on both sides of the ball.
Frequently asked questions
What thread does the FLURO GALSW 6 rod end have?
The FLURO GALSW 6 rod end features an M6 male (external), left-hand thread. The thread length is 21 mm.
What bolt fits the bore of the GALSW 6 rod end?
The ball bore diameter is 6 mm, so it accepts an M6 (6 mm) bolt or pin.
What load rating does the FLURO GALSW 6 support?
The maximum static load rating is 6.0 kN (1349 lbf), and the dynamic load rating is 9.3 kN (2091 lbf).
Does the GALSW 6 rod end require lubrication?
No. The rod end is maintenance-free – the bearing liner has a PTFE sliding layer that must not be lubricated. The rod end has no grease nipple.
What is the difference between GALSW 6 and GASW 6?
GALSW 6 has a left-hand thread, whereas GASW 6 has a right-hand thread. Pairing right-hand and left-hand rod ends on opposite ends of a single tie rod allows turnbuckle length adjustment without disassembly.
What is the tilt angle of the GALSW 6 rod end?
The ball tilts by 13° in each direction, giving a total misalignment angle of 26°.
What materials is the FLURO GALSW 6 rod end made of?
The housing is turned from free-cutting steel and zinc-plated, the liner 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 6 rod end.
