Description

MRA 2437 LLB - 24mm x 37mm x 7mm -


 


ABEC-5


This Angular-Contact ABEC-5 bearing features deep-groove design races, with Grade 10 balls, dual-lip labyrinth (LLB) seals to withstand daily abuse of use and the elements, and to contain the 90% fill Mobilux NGLI 2 high pressure water proof synthetic grease. When properly installed (black seal facing in) and adjusted, Enduro Angular Contact (A/C) 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.


 


Ceramic Hybrid


Ceramic-Hybrid, Angular-Contact, ABEC-5, bottom bracket Bearing featuring 52100 high-Carbon chromium alloy races paired with grade 5 Silicon-Nitride Ceramic balls with 90% fill, high-pressure, water-proof grease. Si3N4 Ceramic balls reduce bearing wear and increase bearing life by eliminating steel on steel contact within the bearing. When properly installed (black seal in for BBs) and adjusted, Enduro Angular contact (A/C) 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. This is particularly important in applications like BBs, there there are constantly changing lateral loads on the bearings, which is typically the primary cause for premature bottom bracket bearing failure.


 


Stainless Steel


Angular-Contact, ABEC-5, Bottom Bracket bearing featuring 440C stainless steel alloy races and balls with 90% fill, high-pressure, water-proof grease for maximum corrosion resistance. When properly installed (black seal in for BBs) and adjusted, Enduro Angular Contact (A/C) bearings engage all of the bearing's balls to spread the force over a larger surface area, minimizing wear and increasing bearing life. This is particularly important in applications like BBs, where there are constantly changing lateral loads on the bearings, which is typically the primary cause for premature bottom bracket bearing failure.


Not all stainless steel is created equal.
Enduro only uses 440C stainless steel balls and races to provide long life and superior corrosion resistance in applications and environments that may be less than ideal. 440C has the highest strength, hardness, and wear resistance of all the standard 440-series stainless alloys with high carbon content. As expected, it is also the most expensive of the 440 series alloys and requires multiple rounds of heat treatment and cryogenic treatment to achieve its superior mechanical properties. Though stainless steel has 20% less load capacity and is slightly softer than our standard 52100 chromium steel used in most of our bearings, stainless steel is an excellent alternative for use in wet conditions, if you wash your bike often, or where sweat can be a problem.


Enduro stainless bearings all carry a full two year anti-corrosion warranty.


 


 


The most common use for this bearing is as a direct replacement bearing for Shimano bottom brackets with a 24mm OD spindle.


 


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. Our 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 full labyrinth to provide long life and superior protection against the elements.
