ENDURO 3803W Hub Bearing - 17mm x 26mm x 10mm

This extra wide bearing is being used by Industry Nine in their rear hubs and by TREK as well as Niner bike as a suspension pivot. 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?

3803W | Abec-3

• Deep groove design races
• Grade 10 balls (high carbon chromium steel)
• Fill with high pressure water proof grease

CH 3803W | Ceramic Hybrid\

• Deep groove design 52100 High-Carbon chromium alloy races
• Grade 5 balls (Silicon-Nitride Ceramic) increase bearing life

CXD 3803W | XD-15 the ultimate upgrade
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
• Grade 5 balls (Silicon-Nitride Ceramic) increase bearing life
• Fill with Kluber NBU52 grease that runs smoother with time and highly resistant to being washed out
• Static load: 616lbf/ 2.74kN
• Weight: 15.5g
