Talk:Ball joint

Disambiguation
Anatomy: There are four major "ball joints" in the human body (and of many animals), attaching the limbs. The joint consists of the end of a bone (femur or humerus) formed into most of a sphere, held into a socket formed in a mating bone structure (hip or shoulder), by muscles and ligaments, which allow three degrees of freedom of movement (X and Y swing, & axial rotation).  Automotive: (As given, perhaps with a cross-reference to extensive discussion of the Heim joint.) Wikidity (talk) 22:12, 3 October 2010 (UTC)

Merger discussion: Heim joint
A Heim joint does not have a separate ball-pin, and is therefore not the same as a ball joint
 * Agreed, the two are fundamentally different and so should not be merged. Pyrope 16:40, 5 August 2007 (UTC)


 * I think that if this article were improved and had graphics, the Heim joint could be included as a variant. I have never heard of a Heim joint and doubt if many people would look it up under that name. Longinus876 13:56, 4 August 2007 (UTC)

A Heim joint is common automotive terminology and is pretty different in application from a ball joint. They should NOT be merged. If you are looking to include something with Heim joint, they are also sometimes knows as spherical bushings. Personally, I don't like that term. —Preceding unsigned comment added by 209.253.35.194 (talk) 22:33, 4 September 2007 (UTC)

THEY DO NOT BELONG BEING MERGED THEY ARE NOT THE SAME AND COULD MAKE IT HARDER TO LOCATE AT THAT POINT! —Preceding unsigned comment added by 170.215.207.54 (talk) 19:51, 9 November 2007 (UTC)

The article on ball joints warns against confusing them with Heim joints. Then turns around and describes the ball joint as a Heim joint(application wise).

I agree that the articles should not be merged as they are not the same product. Also, there are more applications than just automotive for ball joints. one other point, Heim is a registered trademark owned, I believe, by RBC Bearings. Rod End Bearings is the more generic term for Heim Bearings or Heim Joints, even though this is how they are frequently referred to.

Also, I've been noticing something about Wikipedia which needs attention. I'm not sure what to suggest but here is the issue: When I look up something scientific or historical or just over the heads of most people, the articles are great. But a question concerning everyday things, especially cars and the like, it seem everybody thinks he's an expert. There is much misinformation in these areas. Also in the discussion sections it's pretty obvious that these contributors should be just put together in a room somewhere. It's really just a food fight. All kinds of extraneous info and emotion flying all over the place. I vote for some restraint. Longinus876 13:48, 15 November 2007 (UTC)

A pen and a pencil are both thin tools used for making markings. Therefore, they should have the same article, amirite? —Preceding unsigned comment added by 66.168.71.168 (talk) 06:12, 11 February 2008 (UTC)

Wear & Variations
Might it be worth scratching together a section on wear characteristics (or improving what's there, at least) and the variations on uses? Ball joints are so common in some form or another that it's worth pointing to the oddballs, like electric solenoid governor linkages and other solenoid linkages, control levers, etc.

I agree that the ball joint is distinct enough from a Heim ("rod end") to warrant its own article. Their applications are different. Most commonly, though, I've heard a rod end joint referred to as rod bearing. 184.153.196.39 (talk) 04:05, 5 February 2011 (UTC)
