Bearing Enduro SMR 18307 LLB 18×30×7, Stainless Steel

Bearing Enduro SMR 18307 LLB 18×30×7, Stainless Steel

The Enduro SMR 18307 LLB is a stainless steel radial bearing, engineered for reliable performance in wet and demanding environments. The races and balls are manufactured from 440C stainless steel and paired with Grade 10 precision balls, ensuring smooth rotation and long service life.

This bearing features dual-lip LLB seals and is packed with a 90% fill of Mobil XHP 222 high-pressure waterproof grease, providing excellent protection against water, dirt, and everyday wear. Its deep-groove race design supports stable operation and consistent load distribution.

This bearing is most commonly used as a bicycle hub bearing, but it can also be applied as a pivot bearing. For suspension systems exposed to higher and multi-directional loads, a dedicated MAX-type bearing is recommended.

Enduro exclusively uses 440C stainless steel, which offers the highest strength, hardness, and wear resistance of all standard 440-series stainless alloys. Although stainless steel has approximately 20% lower load capacity and is slightly softer than standard 52100 chromium steel, it is an excellent choice for wet conditions, frequent bike washing, or environments where sweat can be an issue.

All Enduro stainless steel bearings are backed by a two-year anti-corrosion warranty. Like all Enduro bearings, this model is engineered with the deepest possible race grooves and dual-lip seals riding in a micro-groove, forming a full labyrinth that provides long service life and superior protection against the elements.
