Bearing Enduro Bearings S6901 LLB Stainless

The Enduro Bearings S6901 LLB Stainless radial bearing has C3 clearance, 440C stainless steel races, Grade 10 balls and dual seals. It is 90% filled with Mobil XHP 222 high-pressure, waterproof grease.

• Dimensions: 12 × 24 × 6 mm
• Static load: 254 lbf / 1.13 kN
• Weight: 10.4 g
• Full two-year anti-corrosion warranty

This radial bearing is generally used as a hub bearing in some quick-release hub designs and in pedals. It can also be used as a suspension pivot bearing, although the MAX-type version of this bearing is better suited for suspension use.

440C stainless steel

Enduro uses only 440C stainless steel balls and races to provide long service life and greater corrosion resistance in less-than-ideal conditions. Of the standard 440-series stainless steel alloys, 440C has the highest strength, hardness and wear resistance, as well as a high carbon content. It is also the most expensive of the 440-series alloys; several rounds of heat treatment and cryogenic treatment are required to achieve its mechanical properties. Stainless steel has 20% less load capacity and is slightly softer than the standard 52100 chromium steel used in most Enduro bearings. It is an excellent alternative for wet conditions, frequent bike washing or situations where sweat can be a problem.

Enduro bearing construction

Enduro bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15, with ceramic or stainless steel balls. The bearing races are engineered with the deepest possible grooves to accommodate the largest possible balls. Dual-lip seals ride in a micro-groove, forming a labyrinth for protection against the elements.
