About Springfix Linkages
Springfix Linkages has been supplying quality linkages and assemblies to our customers since 1995. Our extensive product line includes rod ends, clevises, ball joints and complete linkages in a wide range of materials and finishes. We service over 350 companies in a wide range of industries throughout North America. The knowledgeable staff here at Springfix Linkages are always available to assist you with any special applications you may have. Every application is unique. Therefore we use this knowledge to design a rod end, clevis, or ball joint that supports your environment, height and weight requirements, length of use, and purpose. Springfix Linkages will work one-on-one with you to design a cost effective and suitable linkage for your application.

All threaded products should be tightened to the torque value appropriate to both material grade and the thread size. Wherever vibration occurs, the use of self-locking nuts or lock washers is recommended.
Please ensure that there is sufficient thread engagement to provide an adequate factor of safety. When fitting or adjusting threaded rods into linkage components, a minimum of one and a half diameters of thread engagement is advised.
We manufacture all traditional thread forms and pitches including BA, BSF, BSW, UNC, UNF plus ISO coarse and fine pitch metric threads.
Where feasible, to minimize wear, Ball Joints should be mounted and protected with the housing above the ball stud to reduce the ingress of contaminants.
Care must be taken when adjusting linkage assemblies to ensure that the ball studs operate within their specified articulation angle as shown on the individual product page, over the full travel of the assembly. If practicable, a mechanical stop should be incorporated into the design to prevent any overrun.
Using lighter weight connecting rods can in some cases alleviate premature wear This can occur when there is vibration in the linkage assembly and is particularly relevant when using ‘all steel’ ball joints. Alternatively, consideration should be given to the use of composite Ball Joints such as the ‘A’ series.
Fitted protective Gaiters are an option for most Ball Joints and should be specified when they will operate in wet or abrasive environments. In some applications the Gaiter will also assist in damping down vibration. Please note that in some cases a fitted Gaiter will reduce ball stud articulation. Gaiters featured on this web site are always molded in Polychloroprene.
Stainless Steel Ball Joints are available for use in corrosive environments.
Because of the synthetic materials featured in certain Ball Joints and Rod Ends, the overall recommended operating temperature range for our products is minus 40°C/40°F to plus 100°C/212°F. However, many products will function outside this range so please contact us for performance advice: visit the Special Test Facilities page. All ball joints studs and bodies are assembled with a high performance grease.
Metric and Inch Rod Ends based on DIN ISO 12240-4 (DIN 648), are available female or male, RH and LH threads with or without studs.
The standard finish, except for CM and IMG products, is zinc plated and yellow passivated, our codes F1 or F11, including routine de-embrittling, where relevant. The standard finish for CM and IMG products is zinc plated and clear passivated including routine de-embrittling, where relevant, our codes F2 or F12. In blind holes, such as Ball Joint bodies, only partial plating is achievable.
