RE Series
Двухсоставное внутреннее кольцо Подшипники скрещенных роликов
20–600mm Bore | Integral Outer Ring | Двухсоставное внутреннее кольцо | P5/P4/P2 Grade
The RE series имеет an integral (one-piece) наружное кольцо with a two-piece (split) внутреннее кольцо — the inverse of the RB series. This design is specifically optimized for applications where the наружное кольцо is the rotating element and наружное кольцо rotation accuracy is the primary performance requirement.
Подшипники скрещенных роликов Optimized for Outer Ring Rotation Применения
Luoyang Songju RE series подшипник скрещенных роликовs feature an integral one-piece наружное кольцо and a two-piece (split) внутреннее кольцо — the structural inverse of the RB series. This design обеспечивает the most stable, accurate reference surface on the наружное кольцо, making RE bearings the optimal choice when наружное кольцо rotational accuracy is the primary requirement.
The RE series shares the same overall mounting dimensions (bore × OD × width) as the RB series, enabling direct substitution in existing designs. The key difference is which ring is split: RB splits the наружное кольцо (for внутреннее кольцо rotation accuracy), RE splits the внутреннее кольцо (for наружное кольцо rotation accuracy). This interchangeability gives designers flexibility without changing корпус or вал dimensions.
Standard RE bearings feature four смазка пластичной смазкой holes in the наружное кольцо for convenient relubrication access. Доступно в P5, P4, and P2 класс точностиs from подшипниковая сталь GCr15. Открытый type (standard) and sealed type (suffix UU, single or double seal) configurations. The full complement design maximizes грузоподъёмность для ответственных применений.

Почему выбирают Luoyang Songju RE Series Подшипники скрещенных роликов
Optimized for наружное кольцо rotation — same dimensions as RB, inverse ring configuration
Optimized for Outer Ring Rotation
The integral (one-piece) наружное кольцо обеспечивает the most stable, accurate rotating reference surface when the наружное кольцо is the driven element. Идеально для hollow-вал поворотный столs, direct-drive turntables, and applications where the central bore must remain clear for cable or fluid pass-through.
RE/RB Dimensional Interchangeability
RE bearings share identical bore × OD × width dimensions with RB counterparts. Designers can evaluate both ring configurations in the same корпус — enabling rapid prototyping and design optimization without mechanical changes to adjacent components.
Four Пластичная смазка Смазка Holes
Standard RE bearings feature four grease ports in the наружное кольцо, providing convenient access for relubrication without disassembly. Compatible with grease, oil-mist, and масляно-воздушная смазка systems for flexible integration into existing machine lubrication circuits.
Двухсоставное внутреннее кольцо Design
The split внутреннее кольцо облегчает подшипниковая сборка and disassembly — particularly advantageous for large-bore bearings (200mm+) where handling a single-piece внутреннее кольцо would be impractical due to weight and size.
Full Complement — Maximum Load
Like the RB series, RE bearings use a full complement roller design without a cage or сепаратор. This maximizes the number of load-carrying rollers and обеспечивает the highest possible load ratings for applications with significant overturning moments and combined loads.
THK RE / IKO Interchangeable
Прямая размерная замена for THK RE series and IKO equivalent подшипник скрещенных роликовs. Same mounting envelope, same performance specifications — конкурентные цены with support from our Luoyang application engineering team.
Отрасли и применения for RE Series Подшипники скрещенных роликов
RE Series подшипник скрещенных роликовs are trusted across a wide range of precision industries worldwide.
Hollow-Shaft Rotary Tables
RE bearings with their integral наружное кольцо are the preferred choice for hollow-вал поворотный стол designs where cables, coolant lines, or laser paths must pass through the bearing center — common in 5-axis machining and laser processing equipment.
Robot Wrist & End-Effector Axes
Outer ring rotation is typical in robot wrist joints and end-effector rotary axes. RE bearings ensure the rotating tool фланец поддерживает precise positioning accuracy under combined payload, process force, and moment loads.
Solar Tracking & Positioners
Large RE bearings (bore 300mm+) support azimuth and elevation rotation in solar tracking systems, heliostats, and precision optical mounts. Integral наружное кольцо обеспечивает the stable reference needed for accurate sun-tracking over decades of outdoor exposure.
Inspection & Measurement Systems
Coordinate measuring machines (CMMs), optical comparators, and CT scanning systems rely on RE bearings for smooth, accurate rotation of measurement axes. P2 grade bearings with minimal runout enable sub-micron measurement accuracy.
