种类与说明

Types and Features

CRA超薄系列（内圈旋转）CRA Thin Type

CRA系列是把内圈和外圈的壁厚做的很薄的小型轻量的交叉滚子轴承，既小型又能承受重负荷，因此轴承坐和侧面压紧法兰盘都可以轻量化， 于机器人的手部等旋转关节部分。这个系列的外圈是由两部分组成，用铆钉固定后成为非分开形式。

The CRA series is the inner ring and the outer ring wall thickness do cross roller bearings are compact and lightweight thin, is small, can bear heavy load, so the bearing seat and the side pressing flange can be lightweight, most suitable for robot hａnd rotary joint. This series of the outer ring is composed of two parts, fixed by rivets become non separated form.

CRB标准系列（内圈旋转）CRB Thin Type

CRB系列的内外圈尺寸被最小限度的小型化，其结构是外圈为两部分组成，内圈是一体的设计， 于要求内圈旋转精度高的地方。

Inside and outside the ring size CRB series are miniaturized minimal, its structure is the outer ring into two parts, inner ring is one of the most suitable for the requirements of design, the inner ring rotation accuracy high places.

CRE标准系列（外圈旋转）CRE Thin Type

CRE系列是由CRB系列的设计理念产生的新形式，内圈有两部分组成，外圈为一体的构造， 于要求外圈旋转精度高的地方。

The CRE series is a new form of generated by the design concept of CRB series, the inner ring is composed of two parts, the outer ring structure as a whole, the most suited to the requirements of the rotating precision outer high places.

出色的旋转精度

Excellent Rotation accuracy

因在垂直排列的滚子间装有间隔保持器，防止了滚子的倾斜或滚子的相互摩擦，可以有效防止旋转扭矩的增加。另外，不会发生滚子的一方接触现象或者锁死现象。同时，因内圈或外圈是两半分割的构造，轴承间隙可调整，即使被施加预紧，也能获得高精度的旋转运动。

Because the roller arranged vertically is arranged between the spacer retainer, prevent the mutual friction roller tilt or roller, can effectively prevent the increase of rotating torque. In addition, phenomenon will not occur on one side of the roller contact phenomena or lock. At the same time, because of the inner or outer ring is constructed in two segmentation, bearing clearance can be adjusted, even if is applied preload, rotational motion can obtain high accuracy.

操作简易

Easy Handling

被分割两半的内圈或者外圈，在装入滚子和间隔保持器后，被固定在一起，所以安装特别简单

Split the two halves of the inner or outer ring, is arranged in the roller and interval retainer, are fixed together, so the installation is very simple
