681Подшипник накладки грифа XZZ для плавной и точной работы накладки грифа

Любители грифов и дизайнеры миниатюрного оборудования часто сталкиваются с одной и той же проблемой.: finding a bearing that delivers smooth rotation while maintaining durability in extremely limited space. A standard bearing cannot always meet the size and precision requirements of small applications. The подшипник грифа from XCCZC Bearing solves this problem with a compact 1.5×4×2mm structure, точное производство, and reliable performance for fingerboard wheels and miniature mechanisms.

Precision 681XZZ Fingerboard Bearing Designed for Miniature Applications

The 681XZZ miniature deep groove ball bearing is engineered specifically for applications requiring low friction, компактный размер, and stable rotation. Although it is smaller than traditional skateboard bearings, it uses the same fundamental principles: гонки из закаленной стали, прецизионные шарики, and optimized ball guidance.

The bearing specifications include:

• Модель: 681XZZ
• Внутренний диаметр: 1.5 мм
• Внешний диаметр: 4 мм
• Ширина: 2 мм
• Материал: хромированная сталь GCr15
• Твердость: 60–65 ПЦР
• Дизайн щита: Двойные металлические щиты (ЗЗ)
• Прецизионный класс: ABEC-3 to ABEC-9 equivalent
• Тип подшипника: Миниатюрный радиальный шарикоподшипник

Why Choose XCCZC 681XZZ Miniature Deep Groove Ball Bearing?

When you select a miniature bearing, size alone is not enough. You need consistent rotation, protection against contamination, и длительный срок службы.

Smooth Rotation for Better Fingerboard Control

The 681XZZ uses precision-ground raceways and Grade G10 or better chrome steel balls. This design reduces rolling resistance and allows fingerboard wheels to spin freely.

You can achieve:

• Longer roll distance after each push
• More stable trick execution
• Reduced vibration during landing
• Improved control for kickflips, сальто на пятке, и измельчает

Compact Structure for Limited Installation Space

The 1.5×4×2mm dimensions allow the bearing to fit small fingerboard wheels without adding unnecessary weight.

Это делает его пригодным для:

• Professional fingerboard setups
• Custom fingerboard wheel designs
• Miniature mechanical assemblies
• Hobby engineering projects

Double Shield Protection for Longer Service Life

Fingerboards are frequently used on desks, ramps, concrete surfaces, and other environments where dust and small particles exist.

The ZZ double metal shields help:

• Prevent dust and debris entry
• Retain internal lubricant
• Reduce maintenance frequency
• Maintain stable rotation performance

681XZZ Fingerboard Bearing vs Standard Mini Bearings

Different miniature bearing designs provide different levels of performance. The following comparison helps you understand why the 681XZZ is suitable for fingerboard applications.

Applications of 681XZZ Precision Miniature Bearing

Although designed for fingerboards, this precision deep groove ball bearing supports many compact applications.

Common uses include:

• Пальцевые скейтборды: Provides smooth wheel rotation for tricks and daily practice.
• Mini RC Cars: Supports small wheel hubs and gear systems.
• Микро Моторы: Suitable for compact motors, фанаты, and rotating components.
