Lucas E3LM Bearings

Is is my measuring or are these two bearings metric?

Also, I cannot see any disadvantage of replacing with shielded both sides as opposed to open.

Would appreciate anyone's thoughts.

Regards

Pat

Hi Pat,
Yes metric bearings are used, get 2RS versions (double rubber seals)

These should be very cheap to buy, apparently they are a common size in skateboards!

6202 & 608. RS for rubber seals.

 I always used to pull one seal out and stuff in more grease, but gave up on that a while ago when I was assured that the amount of grease from factory is sufficient for the life of the bearing
 That's not hard to understand if the bearing finally dies and there's no grease left ....

 but seriously, in my opinion double seals are better whether or not they are 'extra-filled' (there was at least one discussion about this a while ago)

I just fitted similar skf bearings to a brush cutter crankshaft, the shop only had the sealed type, so I had to remove the rubber seals both sides given they were designed to get the petrol/oil mix as a lubricant.

 I then had to heat the bearings up a fair bit to get them on the crankshaft (interference fit from hell) and the white grease skf filled them with did not show any signs of softening or melting.......unlike normal grease. It’s special stuff for sure, I would not mess with it!

The amount of grease is more than adequate for the hard industrial usage these bearings are made for, let alone the use it will get in soft gentle use in an old BSA. There is no need to stuff bearings with grease, in fact more than 2/3rds full is too much.
