Link Balls (RBL, RBI, TBS, ABI)

Link Balls (RBL, RBI, TBS, ABI)

RBL
RBI
TBS
ABS

These are low priced rod-ends, manufactured by attaching a stud by friction welding, to a bearing steel ball and using this for movement in a diecast holder. The spherical slide part is finished to a mirror finish and they have excellent wear resistance. They have a large oscillation angle.

Numbering System
The RBL + Size in mm.
If a boot is added (as shown in the diagram above, add D. For left hand thread, add L).

Eg. RBL10DL - 10mm with boot and left hand thread.

When supplied, the boot is Neoprene rubber. When the boot is added the inclination angle is reduced by 5%-10%.

General Comments

We rely on our customers to select the type and size of rod end for their particular job. The factors which they will have to consider include Dynamic and Static load, Rotational speed and operational conditions.

Rod ends normally take radial loads but can take thrust loads and the proportion of thrust to radial load needs to be taken into account in the selection process. There is a limit to the operating speed which IKO sets at 30 m/min. There is also a limitation on the permissible angle of tilt and this is shown in the manufacturers catalogues.

The threaded shanks of rod ends are comparatively long and this feature permits an adjustment to be made to the operating position of the rod end. However, the section of thread in contact with the mating rod should be at least 1.25 times the diameter of the thread.

Ball Joint Assemblies

Ball joint assemblies are used as part of a linkable system in industrial applications. The SPG type is a high strength design with good wear resistance suitable for heavy duty service. SPG type is fitted with a weather resistant dirt shield. Type SP is similar but without the dirt shield.

These products are made from low carbon steel with the ball stud surface hardened for wear resistance. The ball cavity is packed with high wear lubricant.

Part Numbers
SPG - Shielded Type
SP - Unshielded Type

The numeric part of the number is not related to the size but is nearly a part number. For left hand thread add the suffix LH.
Eg. SPG100441 = Shielded type, 3/8.24 / left hand thread.
