Rod end FLURO EA 17 – M16 male, right-hand, steel/steel bearing (uniball)
- Rod end FLURO EA 17: M16x2 right-hand male thread, 17 mm bore, load capacity 54.0 kN static / 21.2 kN dynamic, steel/steel bearing. 1 pc.
FLURO EA 17 Rod End – M16 Right-Hand Male Thread, 17 mm Bore, Steel/Steel Bearing
FLURO EA 17 is a rod end (also referred to as a rose joint, heim joint, spherical rod end, or threaded uniball) featuring an M16 right-hand external (male) thread and a 17 mm ball bore diameter. It supports a static load of up to 54.0 kN and a dynamic load of up to 21.2 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.
In size 17, the rod end has a 17 mm ball bore diameter, whereas the shank thread is M16. The number in the EA 17 designation refers to the bore diameter rather than the thread size.

Construction and Materials
Housing (body with threaded shank)
The size 17 housing is forged from C45 (AISI 1045) quenched and tempered 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 M16 size include:
- pneumatic and hydraulic cylinders,
- lever systems and linkages in machinery,
- rods and links transmitting alternating loads,
- tubular structures, tie rods, and bracing,
- 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 17 mm diameter bolt or pin passes through the ball bore.
- Secure the threaded shank using an M16 jam nut.
- The threaded shank should be engaged to a minimum depth of 1.5 times the thread diameter, i.e., at least 24 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 17 rod end have?
The FLURO EA 17 rod end has an M16 external (male), right-hand thread. The thread length is 36 mm.
What bolt size fits the EA 17 bore?
The ball bore diameter is 17 mm, so it accommodates a 17 mm diameter bolt or pin.
What load can the FLURO EA 17 handle?
The maximum static load rating is 54.0 kN (12140 lbf), and the dynamic load rating is 21.2 kN (4766 lbf).
Does the EA 17 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 17 and EA 17 D?
EA 17 has a steel/steel bearing that requires lubrication, whereas EA 17 D has a maintenance-free bearing. The mounting dimensions of both versions are identical.
What is the difference between EA 17 and EAL 17?
EA 17 has a right-hand thread, whereas EAL 17 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 17 rod end?
The ball tilts 10° in each direction, for a total of 20°.
What materials is the FLURO EA 17 made of?
The housing is forged from C45 (AISI 1045) quenched and tempered 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 17 rod end.
