ACL bearing HX marking identification
 

Not an ACL bearing guru, hoping someone in this forum knows.

Is there a specific marking on HX ACL bearings that identifies them as HX vs H assuming both are STD (standard). The bearings I have in front of me don't have H or HX anywhere on them but the part number and size is stamped along with ACL logo.

All my hx and h bearings are stamped with hx or h. Sealing package/Cover too

Re: ACL bearing HX marking identification
 

Odd, these don't have H or HX stamp, got a picture of yours you can share?

Re: ACL bearing HX marking identification
 

I mic'd them with my mitutoyo and they are as thick as the greens in the thickest part so I'm sure they are H but odd there isnt a stamped H or HX like the others. Will call ACL Monday to confirm and post back in case anyone else has same question.

Re: ACL bearing HX marking identification
 

I've been on the acl website there is no pictures of the identification marks. Do you have pics yourself of bearings?

Re: ACL bearing HX marking identification
 

Here is a pic, they are used on GSR crank with forged rods even though they are D series bearings, not here to debate why so don't ask, looking for identification info only.....

Re: ACL bearing HX marking identification
 

Are you saying the bearings i posted are Aluglide and not H or HX? Are you saying this bc there is no marking?

Re: ACL bearing HX marking identification
 

the problem is whatever i say..u dont believe it...see oil pan thread. u need for everything pictures and measurements. i said the answer for u. ive build many engines and have a litlle bit experience of all bearings on the market.

Re: ACL bearing HX marking identification
 

Only problem is that max wall at crown is 0.0592 for the Aluglide and I only got 0.0590 which is the H spec per ACL matrix

Re: ACL bearing HX marking identification
 

I asked a simple question about how you made that determination on the bearing. The measurements don't match the spec, are you saying the specs are wrong? Not sure what you are getting up.

Re: ACL bearing HX marking identification
 

This is why you can't simply trust, you need to trust but verify.

As I suspected based on what ACL told me via phone, these are the older H model bearings. They used to be called the "P" series bearings and bc of how old they are the P didn't always get stamped on the bearing. The tri metal P is similar to H race series now.

So for anyone else with older bearings therr you have it if you have ACL without markings. I'm going to cut a bearing in half to confirm as a sanity check.

Cheers

Also noting F780 and F781 are the same material off the ACL catalog for this and the H model.

It's about getting the facts right. People have opinions and it is just that, no need to get offended for verification of information.

To further prove these are not the Aluglide I took a grinder to the surface and sure enough there is a copper layer, the aluglide is aluminum through with silica. Another give away is there is a copper trace at the Tang across the length. Also they didn't make the HX back than so the replacement is the H model
