Details
The most common use for this bearing is as a direct replacement bearing for Shimano external cup BBs when using the plastic Shimano bearing insert. If you wish to avoid using the plastic insert MR 2437, this is the correct bearing for the job.
The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15 with ceramic or stainless balls. Enduro's bearings are always engineered with deepest groove races possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.

WHICH BEARING TO CHOOSE?
61805 | Abec-5
- Deep groove design races
- Grade 10 balls (high carbon chromium steel)
- Fill with high pressure water proof grease
- Higher tolerances and higher quality output than ABEC-3
- Static load: 563lbf / 2.50kN
- Weight: 20.4g
In standard radial bearings, only three or four of the balls make contact during load. But Enduro angular contact bearings work differently. When properly installed and adjusted (black seal facing in), Enduro angular contact bearings engage all of the bearing's balls to spread the force over a larger surface area, decreasing friction, minimizing wear and increasing bearing life.
- Deep groove design races

- Static load: 563lbf / 2.50kN
- Weight: 18.74g
The most impressive feature of XD-15 ceramic-hybrid bearings is, unlike other bearings, they only get better with time and use. As the bearings wear-in, the super-hard ceramic balls actually make the XD-15 races even smoother. So, when compared to other ceramic-hybrid bearings on the market that claim speed and power advantages on day one, Enduro XD-15 bearings not only provide the same initial advantages on day one, but will become faster and smoother with time and use, while the other ceramic-hybrid options will only get slower. Enduro is so confident in the performance of their XD-15 Ceramic-Hybrid bearings that they carry a limited lifetime warranty against wear and corrosion.
- Deep groove design corrosion-proof, cryogenically treated nitrogen steel races

- Fill with Kluber NBU52 grease that runs smoother with time and highly resistant to being washed out
- Static load: 591lbf / 2.63kN
- Weight: 18.7g
