CRBH Series
Высокая жёсткость Подшипники скрещенных роликов
20–250mm Bore | Integrated Inner/Outer Ring | P5/P4/P2 Grade | POM Separators
The CRBH series имеет an integrated (one-piece) inner and наружное кольцо structure, making it the most versatile подшипник скрещенных роликов for general industrial applications. POM plastic сепараторs between each cylindrical roller ensure low-friction, smooth rotation with stable torque characteristics. Предназначено для сочленение роботаs, machine tool rotary axes, medical positioning equipment, and precision inspection systems.
High-Жёсткость Integrated Подшипники скрещенных роликов for Industrial Automation
Luoyang Songju CRBH series подшипник скрещенных роликовs feature an integrated (one-piece) inner and наружное кольцо structure manufactured from вакуумно-дегазированная подшипниковая сталь GCr15. The perpendicular (90°) cylindrical roller arrangement in V-groove raceways позволяет simultaneous support of radial, axial (both directions), and moment loads with a single compact подшипниковая сборка.
POM (polyoxymethylene) plastic сепараторs between each roller reduce friction, prevent roller-to-roller contact, and maintain consistent roller spacing throughout the rotation cycle. This results in smooth rotational torque, reduced рабочая температура, and higher permissible speeds compared to full-complement designs — making the CRBH ideal for continuous-rotation applications.
The integrated ring structure упрощает installation — both inner and наружное кольцоs are one-piece, eliminating the need to manage separate ring halves during mounting. Стандартные модели доступны in P5, P4, and P2 класс точностиs. Открытый type (standard) and sealed type (suffix UU) with dual synthetic rubber seals are available for contamination protection.

Почему выбирают Luoyang Songju CRBH Подшипники скрещенных роликов
The most versatile подшипник скрещенных роликов — integrated ring structure for reliable industrial automation
Integrated Ring Structure
Both inner and наружное кольцоs are one-piece (integrated) design — eliminating the need to manage separate ring halves during installation. Simplifies mounting, снижает assembly time, and гарантирует consistent bearing performance across production batches.
3–4× Higher Жёсткость
Линейный контакт между цилиндрическими rollers and V-groove raceways обеспечивает 3–4 times greater жёсткость than equivalently sized double-row angular contact шарикоподшипники. Critical for precision positioning applications where deflection under load must be minimized.
POM Separator Технологии
Precision-molded POM (polyoxymethylene) сепараторs between each roller eliminate roller-to-roller friction, maintain consistent spacing, and enable higher rotational speeds than full-complement designs. Results in smooth torque, reduced heat generation, and longer grease life.
Stable Rotational Крутящий момент
Anti-skewing сепаратор design предотвращает roller misalignment during rotation — maintaining consistent friction torque even under fluctuating loads and speeds. Essential for servo-controlled positioning systems requiring predictable motion characteristics.
