Another Marvel of Chinese manufacturing

Did just that and all i see is just two bearings back to back.

There should be spacers tubes at each end as well.

should i adjust the nut to have minimum drag ? or do i tighten all the way and it should be fine ? if i should tighten all the way then the block is faulty. please clarify this point for me as all my knowledge is theoretical from forums and such.

You haven't answered the last statement ie. are there spacer tubes in the block. Also are the bearings AC type or standard ball bearings

I didn't answer because I said in a previous reply that i disassembled them and there are only two bearings inside. I don't know what an AC type bearing is, Would you explain ? Thanks.

There should be spacer tubes either side of the bearings.. A picture of the parts would help. Is there a number on the bearing to identify it and is there an oil seal. AC bearings (which they should be) have to be fitted back to back.

Where did you get them from?

The bearings indeed have a writing on them it is 5001Z. I got BK and FK Blocks and neither are working. I got them from a local seller.
