Lambretta Bearing, Race-Tour standard 52.01 - 52.02mm, rear hub with seal and sealing O ring, Race-Tour, MB

MBP0275K

This is our standard sized 52.01 - 52.02mm MB Race-Tour rear hub bearing which fits all Series 1, 2 and 3 Lambrettas.


A quality bearing to suit standard or tuned scooters. 

Now comes with slight improvments that standard bearings don't come with.

  • Uses a large O ring which gets crushed in the casing to seal once fitted
  • The inner bearing face is chamfered to aid fitting the seal

Comes with a MB seal and comes with our special O ring to help seal the bearing in place in the casing, the bearing now has a recess to locate the O ring.

Uses standard size rear hub seal 32 x 45 x 6mm.

If a standard supplied bearing drops into your casing ask for an oversized bearing as an exchange.

TOP TIP: use a bit of sealer smeared into the O ring groove, stretch the O ring over the bearing and push into the groove, otherwise the bearing will sit proud. Always use a bearing fitting tool to lock the bearing in place MRB0967

Features

  • Comes with chamfers making fitting the seal easier and safer on the inner lip, seal fits in the bearing easier
  • Comes with a new inner O ring to stop oil coming through from the gearbox
  • Uses a standard rear hub size seal
  • Bearing outer sizes are slightly bigger to make a tighter fitting bearing

 

Technical

  • Pre heat the engine casing in the bearing area
  • If you want smear a small amount of silicone/gasket sealer on the bearing before fitting
  • Drop/tap the bearing in place, whilst still hot fit the thick rear hub bearing plate and nip the 4 nuts, this will pull the bearing in place and crush the new O ring
  • When the casing cools, remove the plate, oil the inner bearing race where the seal lip goes, leave the outer face on the bearing dry and push the seal in place, if its tight hammer down equally

Real quality bearing, if it runs and lasts as well as I think it will it's an absolute bargain. I've had What dealers say are quality Italian rear hub bearings but they were terrible compared to this one, and it comes with a seal as well. Nice one MB.

Like every MRB product its top quality this. It went in just like Mark said, simply heat the case and it'll drop right in. Mark also said NOT to freeze the bearing so I didn't and he was spot on. Thanks Mark for another quality performance part.

Timothy S on 28 Feb 2024 asked "TOP TIP: use a bit of sealer smeared into the O ring groove. Would you be more specific about what type of sealer? Thank you Tim Scott LCUSA Member #118"

MB Scooters Ltd replied: Any gasket face sealer

Stephen B on 19 Nov 2022 asked "Hi Mark. Can you tell me what size O ring is fitted to the rear hub bearing please. Thanks."

MB Scooters Ltd replied: Part number MBP0473

Thomas B on 04 Jul 2022 asked "Hi , i fitted the MB rear hub bearing and it went in well . But what did i do wrong ? it doesnt turn , too stiff to move by hand. was freezing the bearing wrong , should i have greased the balls before fitting the seal ? . Should it be that stiff ? or move freely by hand ?.Thanks for any advice"

MB Scooters Ltd replied: I never freeze a bearing to fit it, this gives a wrong fit. But it shouldnt make any difference. The chances are its because you havent oiled or greased the oil seal and inner race and this makes it tight to turn.

John on 18 Sep 2019 asked "Hi Mark. Just received mine in the post. The o ring and seal are already fitted on bearing. Do I need to pop them out to grease or just grease them on the outside. Especially the main seal? Thanks"

MB Scooters Ltd replied: The seal is lubricated, but a drop of oil around the balls wouldnt hurt, the O ring you can fit as is

James M on 27 Apr 2019 asked "In your tech site, you recommend warming the engine casing before you fit this bearing. Is there any danger we might melt the large O ring? Thanks, Jim"

MB Scooters Ltd replied: You don't need to get the casing that hot, even if you did the casing would cool so fast it wouldn't damage the O ring

Nick on 24 Jan 2017 asked "Hi i bought this part a while ago and want to put it in my new engine- It's : "Bearing, rear hub with hub seal, MB MBP0275K" It came with seals on both sides of the bearing - your newer bearing doesnt show the inner seal- not a seal? i realize its not a seal - just need to know if i should pull out?( "

MB Scooters Ltd replied: Rear hub bearings should only have one seal fitted on the outer side. Not sure what you are talking about with an inner seal. Maybe you are confused with a drive bearing?

Steven b on 30 May 2012 asked "Hi, Daft question, just purchased one of these and I'm wondering whether the white plastic insert on the opposite side of the seal (internal) gets removed before the bearing is fitted or does it stay in. Thanks, these "

MB Scooters Ltd replied: It to hold the roller bearing in, so leave as it is
