ENDURO bearings ch mrf 3041 llb - ceramic hybrid - double row (radial) - 30x41 44x7

Upgrade your cycling setup with the CH MRF 3041/44 LLB ABEC-5 Ceramic-Hybrid bottom bracket bearing, specially designed for BB86/92 framesets and BB30 style cranksets. Measuring 30mm x 41/44mm x 7mm, this custom bearing allows direct fitment of 30mm cranks into tight spaces, thanks to its flanged design that presses seamlessly into the BB shell for a clean, secure installation. Crafted with high-performance Ceramic-Hybrid bearings, featuring 52100 high-carbon chromium alloy races and Grade 5 Silicon-Nitride Ceramic Balls with 90% fill, it offers exceptional durability and smooth rotation. The waterproof, high-pressure grease enhances longevity, while the Si3N4 ceramic balls reduce wear and extend bearing life by eliminating steel-on-steel contact. Perfectly suited for BB86/92 framesets and 30mm spindle cranksets (BB386 & BB30). For a more robust solution, consider our double-row bearings (DRF041). The Enduro line includes options in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and D-15 with ceramic or stainless steel balls. All bearings feature deep groove races and dual-lip seals within a micro-groove labyrinth for superior element protection. Static load capacity: 852 lbf / 3.79 kN. Weight: 20.5g.
