CRBT Series
Сверхтонкая Подшипники скрещенных роликов
10–50mm Bore | 5.5mm Cross-Section | P5/P4/P2 Grade | Ultra-Компактная конструкция
The CRBT series is the world's thinnest подшипник скрещенных роликов type, with a поперечное сечение height as low as 5.5mm — achieving a 69% height reduction and 38% weight reduction compared to conventional CRBS серии. Предназначено для applications where every millimeter and gram counts: compact hand robots, surveillance camera pan-tilt units, humanoid сочленение роботаs, and exoskeleton mechanisms.
Ultra-Thin Подшипники скрещенных роликов for Space-Constrained Precision Применения
Luoyang Songju CRBT series super-slim подшипник скрещенных роликовs are manufactured to the highest precision standards in our производственный объект с сертификатом ISO 9001:2015 in Luoyang, China. With a поперечное сечение height of just 5.5mm, the CRBT series достигает dramatic space and weight savings — enabling designers to reduce overall mechanism size or increase вал diameter within an existing корпус envelope.
The CRBT series employs the same perpendicular (90°) cylindrical roller arrangement in V-groove raceways as larger подшипник скрещенных роликовs, with anti-skewing разделительный сепараторs between each roller. This гарантирует smooth, stable rotational torque and consistent running accuracy despite the ultra-thin profile. Разъёмная наружное кольцо design (two-piece наружное кольцо, one-piece внутреннее кольцо) облегчает easy installation and clearance adjustment.
Стандартные модели доступны in P5 (ABEC-5), P4 (ABEC-7), and P2 (ABEC-9) класс точностиs from GCr15 high-carbon chromium подшипниковая сталь. Открытый type (standard) and sealed type (suffix UU) configurations are available. Custom размер отверстияs, preload values, and specialty materials are available upon request for OEM applications.

Почему выбирают Luoyang Songju CRBT Сверхтонкая Подшипники скрещенных роликов
The world's thinnest подшипник скрещенных роликов — engineered for space-constrained precision motion
Ultra-Thin — 5.5mm Cross-Section
At just 5.5mm поперечное сечение height, the CRBT series is the world's thinnest подшипник скрещенных роликов. Achieves 69% height reduction and 38% weight reduction compared to CRBS series — enabling ultra-compact mechanism designs previously impossible with conventional bearings.
Space-Optimized Design
The 5mm width and ultra-thin поперечное сечение allow larger вал diameters within a given корпус envelope, directly increasing mechanism жёсткость. Идеально для humanoid сочленение роботаs, compact surveillance PTZ cameras, and exoskeleton pivot points.
Premium GCr15 Bearing Steel
Rings manufactured from вакуумно-дегазированная GCr15 (100Cr6 / 52100) high-carbon chromium подшипниковая сталь. Through-hardened to 58–64 HRC for consistent hardness, wear resistance, and long-term dimensional stability in precision motion applications.
Separator vs Full Complement Options
Standard type (suffix A) имеет POM plastic сепараторs for smooth low-friction rotation. Full complement type (suffix V) устраняет сепараторs for maximum грузоподъёмность in low-speed, high-load applications. Both types support combined radial, axial, and moment loads.
Открытый & Закрытый Configurations
Открытый type (standard) for greased applications with external sealing. Закрытый type (suffix UU) with synthetic rubber seals on both sides for contamination protection — ideal for dusty industrial environments or where relubrication access is limited.
IKO Interchangeable
Designed as direct dimensional replacements for IKO CRBT series super-slim подшипник скрещенных роликовs. Drop-in compatible with major OEM сочленение робота and compact mechanism designs. Custom mounting hole patterns available on request (CRBTF equivalent).
