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.

The original order didn’t arrive. This was likely due to the Royal Fail losing the package. I phoned Wych Bearings and a replacement arrived within 24 hours. I received good service and a quality product. I will buy from them again in the future.

Wrong bearing!
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.

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.
