Our 11, 12, and 13 series cylindrical roller bearings are the benchmark for reliability in medium-to-heavy industrial applications. Designed to provide maximum radial rigidity and high-speed stability, these bearings are essential for high-performance gearboxes, motors, and mechanical drive systems.
Core Technical Strengths:
Optimized Roller Geometry: Advanced crowning on rollers and raceways significantly reduces edge stress and extends operational life.
High Load Rating: Expertly engineered to support high radial forces while maintaining smooth, low-friction rotation.
Structure Specifics:
NU/N Type: Ideal for non-locating (floating) positions to accommodate thermal shaft expansion.
NJ Type: Features two ribs on the outer ring and one on the inner, allowing single-direction axial location.
NUP Type: Locating bearing with two ribs on the outer and one rib plus a loose rib on the inner for bi-directional axial support.
Material Integrity: Forged from high-grade chrome steel with precision heat treatment for extreme wear resistance.
Series Overview & Models:
11 Series: N311, NJ2311, NJ411
12 Series: NU1012, N212, NJ312, NUP2312, NU412
13 Series: NU1013, NU213, NUP313
