Rod end FLURO EA 6 – M6 male, right-hand, steel/steel bearing (uniball)
- Rod end FLURO EA 6: M6x1 right-hand male thread, 6 mm bore, load capacity 6.9 kN static / 3.4 kN dynamic, steel/steel bearing. 1 pc.
FLURO EA 6 Rod End – M6 Right-Hand Male Thread, 6 mm Bore, Steel/Steel Bearing
FLURO EA 6 is a rod end (also referred to as a rose joint, heim joint, spherical rod end, or threaded uniball) featuring an M6 right-hand external (male) thread and a 6 mm ball bore diameter. It supports a static load of up to 6.9 kN and a dynamic load of up to 3.4 kN. It operates on a steel/steel spherical plain bearing that requires lubrication.
This rod end belongs to the EA series manufactured by the German company FLURO-Gelenklager GmbH, built to dimension series E in accordance with DIN ISO 12240-4. This series is designed for high loads with alternating direction and for connections with limited installation space – series E rod ends are narrower than series K rod ends.

Construction and Materials
Housing (body with threaded shank)
The size 6 housing is machined from free-cutting steel and zinc-plated for corrosion protection. In the EA series, housings up to and including size 10 are machined from free-cutting steel, while from size 12 upwards they are forged from C45 quenched and tempered steel.
Spherical plain bearing
A steel/steel spherical plain bearing of type GE..E operates inside the housing. This sliding pair handles high loads with alternating direction well, but requires lubrication.
Lubrication
The rod end does not have a grease nipple – in the EA series, grease nipples are only fitted from size 20 upwards.
Applications
EA series rod ends are used in linkages that transmit high loads with alternating direction while accommodating angular misalignment. Typical applications for the M6 size include:
- control rods and lever mechanisms,
- pneumatic cylinders and automation systems,
- adjustment mechanisms in machinery,
- light tie rods and links in structural assemblies,
- connections with limited installation width.
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 6 mm (M6) bolt or pin passes through the ball bore.
- Secure the threaded shank using an M6 jam nut.
- The threaded shank should be engaged to a minimum depth of 1.5 times the thread diameter, i.e., at least 9 mm.
- The steel/steel bearing requires lubrication – do not operate it dry.
- To utilize the full tilt angle, use conical misalignment spacers on both sides of the ball.
Frequently Asked Questions
What thread does the FLURO EA 6 rod end have?
The FLURO EA 6 rod end has an M6 external (male), right-hand thread. The thread length is 18 mm.
What bolt size fits the EA 6 bore?
The ball bore diameter is 6 mm, so it accommodates an M6 (6 mm) bolt or pin.
What load can the FLURO EA 6 handle?
The maximum static load rating is 6.9 kN (1551 lbf), and the dynamic load rating is 3.4 kN (764 lbf).
Does the EA 6 rod end require lubrication?
Yes. The rod end operates on a steel/steel bearing that requires lubrication. The rod end does not have a grease nipple – in the EA series, grease nipples are only fitted from size 20 upwards.
What is the difference between EA 6 and EA 6 D?
EA 6 has a steel/steel bearing that requires lubrication, whereas EA 6 D has a maintenance-free bearing. The mounting dimensions of both versions are identical.
What is the difference between EA 6 and EAL 6?
EA 6 has a right-hand thread, whereas EAL 6 has a left-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 EA 6 rod end?
The ball tilts 13° in each direction, for a total of 26°.
What materials is the FLURO EA 6 made of?
The housing is machined from free-cutting steel and zinc-plated, and a steel/steel spherical plain bearing of type GE..E operates inside the housing.
Is the price for a single piece?
Yes, the price is for 1 piece of the FLURO EA 6 rod end.
