| —汽车离合器分离轴承及单元，为汽车的重要零部件，其主要功能是通过轴承轴向移动，实现汽车发动机与传动系统之间的结合或断开，从而使汽车平稳起步、 换挡、停车，并对汽车传动系统超载起保护作用。该类轴承具有自润滑、低振动、离合平稳、使用寿M长等特点，为汽车离合器分离轴承Z佳选择。 △结构形式 轴承具有内、外圈选转，自动调心，轴承单元可推式、可拉式轴向位移，带座与不带座等多种结构供顾客选择。 △产品精度 尺寸公差和几何精度按GB/T307。 配套钢球精度等级20级（国标GB/T308）。 △材料 滚动体材料为GCr15轴承钢，淬硬HRC60—65。 内外圈材料为GCr15轴承钢，淬硬HRC61—65。 冲压零件材料为优质低碳钢。 △特殊说明 装配容易，轴向间隙可调整，需chong分考虑使用中的轴向载荷。 如对轴承噪声、转动力矩等有特殊要求需协商确定。 △标准 GB/T5312—2001汽车离合器分离轴承及其单元（JB-12） Auto Clutch Release Bearing and Its Unit ---auto clutch release bearing and its unit are the important parts of autos. Its main function is to make axial movement with the aid of bearing so as to realize connection and release between auto motor and driving system, and as the result autos can smoothly start, shift gears and stop. Therefore it has a protection function for overload on auto driving system. This kind of bearings is characterized by self-lubrication, low vibration, smooth release and long service life. It is the best choice among auto clutch release bearings.Types of Designs:There are a lot of designs available for customers to choose, such as rotation type of inner & outer races, automatic adjusting center, pushing/drawing-type axial displacement of bearing unit, and structures with or without brackets.Product Precision Accuracy:Dimensional tolerance and geometrical accuracy is based on GB/T307.Matched steel ball accuracy is grade 20 (ISO GB/T308).Materials:Material for rolling body is GCr15 bearing steel, quench-hardening HRC60---65.Material for inner and outer races is GCr15 bearing steel, quench-hardening HRC61---65.Material for punched parts is quality low-carbon steel.Special Directions:Easy to mount, axial clearance adjustable, axial load during operation is fully considered.Special requirements for bearing noise, rotating moment and etc are to be defined through negotiation. |
