61903-2RS (6903 2RS) Sealed Thin Section Bike Bearing - Metric 17x30x7 - SKF Premium Quality

Deep Groove Ball Bearings are the most common bearing type found in a wide variety of applications. Versatile and robust they are available in a wide range of sizes and options including seals, shields and special clearance for high speed applications. The main types are:

  • Open - Bearing without seals or shields, suitable for applications where lubricant will constantly flow through them i.e. gearboxes.
  • Metal Shields (ZZ, 2Z) - Bearings fitted with steel shields and lubricated for life.
  • Rubber Seals (2RS, 2RSR, 2RSH) - Bearings fitted with steel reinforced rubber contact seals which provide a better seal but add friction so are unsuitable for high speed applications, lubricated for life.

Wrong bearing!
Friday, 30 April 2021  | 

My fault but it was the exact number from the old bearing. 1mm too small diameter. Reordered the correct one under a completely different number! Didn't return it as I'll quite possibly use it in future.

Monday, 12 April 2021  | 

although i was more than happy with the ease and speed of service unfortunately the bearings i ordered dont fit the hub on my fulcrum wheel. my own fault obviously but to be fair the number on my old bearings exactly matches the one on the new ones, 61903-2RS.
it appears that the internal diameter of my old bearings are 18mm, the ones i ordered are 17mm so no use to me.

Bike bearings. Excellent replacement for Zipp Cognition
Tuesday, 23 April 2019  | 

After about 10,000 miles one of my bearings was suffering - water had penetrated and they were rusting. I replaced the offending bearing about 1,200 miles ago and it's been running splendidly - absolutely no problems fitting and in use.
