Whether there are bearings for original equipment or for replacement needed - KRW only produces products with the highest quality and the label Made in Germany. In the following product range, all bearing components and bearing series in the application fields of heavy industry, energy & power plants, motors, gear boxes and generators, rail & transportation, shipbuilding and port technology as well as engineering, with their specific characteristics will be presented. 深沟球轴承 深沟球轴承可承受径向和轴向力 该型轴承是使用最广泛的轴承类型 由于此类轴承允许角度误差有限, 所以需要精确安装 此类轴承应用于许多领域, 主要用于高速运转的机械 深沟球轴承价格低廉, 可靠耐用 Deep Groove Ball Bearings Deep groove ball bearings absorb radial and axial forces. They are among the most frequently used bearing types. Due to their limited capability of angular alignment, the bearings must be aligned accurately. They are used in many applications, primarily in machines that operate at high speeds. Deep groove ball bearings are competitively priced and very reliable. 角接触球轴承, 单列 此类轴承可承受单方向较大的轴向力 只在施加轴向负载的情况下能承受离心力 角接触球轴承适用于高速度 Angular Contact Ball Bearings, Single Row This bearing type allows the absorption of large axial forces from one direction. Centrifugal forces can also be included, but only while axial loads are acting. Angular contact ball bearings are suitable for high speeds. 6

7 角接触球轴承, 双列 双列角接触球轴承相当于 O 型排列的两个单列角接触球轴承, 但安装尺寸更小 在方向变化产生较高的径向荷载和推力荷载的情况下, 经常采用双列角接触球轴承 Angular Contact Ball Bearings, Double Row Double row angular contact ball bearings go together with the arrangement of two single row angular contact ball bearings with O-arrangement but with a smaller mounting dimension. Double row angular contact ball bearings are often used, where high radial and thrust loads are transferred from changing directions. 四点接触球轴承 四点接触轴承是单列角接触球轴承的子类, 可承受双向轴向荷载 Q 型四点接触球轴承具有一个分离的外圈 QJ 型四点接触球轴承具有一个分离的内圈 从而确保了其高强度且便于安装的特点 Four Point Bearings Four point bearings are a subgroup of single row angular contact ball bearings which absorb axial loads in both directions. Four point bearings version Q have a divided outer ring. Four point bearings version QJ have a divided inner ring. This concept ensures both high ruggedness and easy installation. 7

8 推力角接触球轴承 推力角接触球轴承是双向有效高精度轴承 主要结合双列圆柱滚子轴承使用, 其中双列圆柱滚子轴承主要负责承载径向力 推力角接触球轴承便于拆卸和安装 Angular Contact Thrust Ball Bearings Angular contact thrust ball bearings are bilateral effective high precision bearings. They are mainly used in combination with double row cylindrical roller bearings, whereat the double row cylindrical roller bearings are responsible for absorbing radial forces. Angular contact thrust ball bearings are easy to disassemble and mountable. 圆柱滚子轴承, 单列 KRW 生产的单列圆柱滚子轴承主要为高负载型 ( 后缀 E) 圆柱滚子轴承采用钢制 铜制实体或玻璃纤维强化 ( 聚酰胺 ) 保持架 圆柱滚子轴承的可分离性使其在安装和拆卸是易于装配 滚子和滚道之间的修正线接触降低边缘应力 Cylindrical Roller Bearings, Single Row At KRW single row cylindrical roller bearings are mainly manufactured as heavy-duty version (suffix E). Cylindrical roller bearings come with steel, solid brass or glass fibre reinforced plastic (polyamide) cages. The simple separability of Cylindrical Roller Bearings facilitates their assembly during mounting and dismounting. The modified line contact between the rollers and races reduces edge tension. 8

9 圆柱滚子轴承, 双列双列圆柱滚子轴承尺寸小, 具备较高的径向承载能力 能抗扭转, 刚性较强 带锥形内孔的游隙可通过移动内圈方便调整 Cylindrical Roller Bearings, Double Row Double row cylindrical roller bearings feature a low profile and offer a high radial load capacity. They are torsion-resistant and very stiff. The radial clearance for tapered bore is easy to adjust by moving the inner ring. 圆柱滚子轴承, 多列 多列圆柱滚子轴承的一大优点是径向承载能力极高 由于滚动体数量多, 冲击力可均匀分布 其摩擦力小于其他类型的多列轴承 多列圆柱滚子轴承不能承受轴向力 但是允许少量的轴向位移 Cylindrical Roller Bearings, Multi Row A big advantage of multi-row cylindrical roller bearings is their very high radial load capacity. Due to the large number of rolling elements the impact force is well distributed. The friction is lower than at other multi-row bearing types. Multi-row cylindrical roller bearing cannot absorb axial forces. However a slight axial displacement is possible. 圆柱滚子轴承 ( 满装 ), 单列 满装圆柱滚子轴承能在低速下承受极高的载荷 开式单列和双列轴承主要用于齿轮箱中 此类无保持架轴承用代号字母 V 表示 Cylindrical Roller Bearings (Full Complement), Single Row Full complement cylindrical roller bearings can withstand extremely high stresses at lower speeds. Unsealed single and double row bearings are used mainly in gear boxes. These cageless bearings are marked with the code letter V. 圆柱滚子轴承 ( 满装 ), 双列 此类型的满装滚子轴承中, 滚动体由坚固的轴承套圈上的挡边引导 此类轴承的承载能力高于单列满装滚子轴承 Cylindrical Roller Bearings (Full Complement), Double Row In this type of full complement roller bearings, the rolling elements are guided by flanges on the massive storage rings. The load rating of these bearings is higher than the load rating of single-row full complement roller bearings. 9

10 圆柱滚子轴承 ( 满装 ), 多列 多列满装圆柱滚子轴承非常耐用和坚固 主要用于有非常高的疲劳应力但速度较低的情况下 此类轴承可用作浮动端轴承 固定端轴承或阶梯轴承 Cylindrical Roller Bearings (Full Complement), Multi Row Multi-row full complement cylindrical roller bearings are very viable and very stiff. They are mainly used in applications where very high fatigue stresses occur, but low speeds prevail. They can be used as floating, fixed or step bearings. 轴箱圆柱滚子轴承 轴箱圆柱滚子轴承是连接铁路车辆车轮和其他部分的轴承 轴箱圆柱滚子轴承和普通圆柱滚子轴承的结构类似 根据不同的应用, 轴承保持架可用玻璃纤维强化聚酰胺 (TN) 或黄铜 (M3) 制造 Axle Box Cylindrical Roller Bearings Axle box cylindrical roller bearings are bearings that act between the wheels and the rest of the rail vehicle. Axle box cylindrical roller bearings have a similar structure to normal cylindrical roller bearings. Depending on the application the cages can be manufactured out of glass fiber reinforced polyamide (TN) or brass (M3). 推力圆柱滚子轴承 由于其设计, 推力圆柱滚子轴承占空间小并能承受较高轴向力和冲击负载 此类轴承一般适用于较低速度的情况 由于轴承内部形状的因素, 滚子和滚道之间会产生较高的滑动摩擦力, 可通过适当的润滑降低摩擦 得益于其可分离性, 推力圆柱滚子轴承也便于安装 Cylindrical Roller Thrust Bearings Due to their design, cylindrical roller thrust bearings use only little space and are able to take up high axial forces as well as impact loads. They are typically used at relatively low speeds. Due to the bearings internal geometry, high slippage forces are produced between raceway and rollers, which can be reduced by appropriate lubrication. Thanks to their separability, cylindrical roller thrust bearings are easy to install. 圆锥滚子轴承 圆锥滚子轴承主要用于需要高额定载荷且需同时承受轴向荷载和径向荷载的情况 此类轴承通常成对安装 (X 型或 O 型排列 ), 以防止轴承完全分离 圆锥滚子轴承具有一定的速度限制 Tapered Roller Bearings Tapered roller bearings are predominantly used in applications where a high load rating is required and where they primarily have to sustain combined radial and axial loads. These bearings are usually installed in pairs (X or O arrangement) to prevent a total discharge of the bearing. Tapered roller bearings are suitable for limited speeds only. 10

11 推力圆锥滚子轴承 推力圆锥滚子轴承能承受非常高的轴向力, 而且尽管轴向空间需求较小, 也能提供良好的抗冲击性能 圆锥滚子轴承非常坚固 Tapered Roller Thrust Bearings Tapered roller thrust bearings can absorb very high axial forces and offer despite their relatively small axial space requirements, an optimum shock resistance. Bearings with Tapered roller bearings are very stiff. 球面滚子轴承, 单列 该球面滚子轴承是具有可调节接触角的单列滚子轴承 此类轴承特别适用于需要高径向承载能力, 并能补偿偏斜的情况 此类轴承坚固的设计在径向冲击载荷的应用中得到了验证 但是此类球面滚子轴承的轴向承载能力非常低 这种轴承不可拆卸 Spherical Roller Bearing, Single Row The spherical roller bearing is a single row roller bearing with adjustable contact angle. This type is especially suited for applications which require high radial load capacity and compensation of misalignment. Their solid design has been proved in applications with radial shock load. The axial load capacity of spherical roller bearings, however, is rather low. These bearings cannot be disassembled. 11

12 球面滚子轴承, 双列 除了带有固定引导挡边或浮动挡边的双列球面滚子轴承,KRW 还生产无挡边的球面滚子轴承 由于其承载能力高, 球面滚子轴承适用于需承受极高荷载的情况 此外, 球面滚子轴承能承受双向轴向力, 具有出色的调心性能, 可消除轴偏斜或轴承座偏斜的影响 Spherical Roller Bearings, Double Row Besides spherical roller bearings, double row with predefined guiding lips or floating flanges KRW manufactures spherical roller bearings without flanges. Because of their high load carrying capacity, spherical roller bearings, double row, are ideally suited for applications where extremely high loads have to be accommodated. Moreover, spherical roller bearings, double row can sustain axial forces in both directions, offering an excellent self aligning capability and are impervious to shaft deflections as well as misalignment of the bearing seats. 推力球面滚子轴承 推力球面滚子轴承是单列轴承, 由于其内部结构, 可以调节角度补偿轴偏斜 坚固的轴圈和座圈以及钢制或铜制保持架, 保证了出色的承载能力 推力球面滚子轴承可承受径向应力, 并适用于高速情况 Spherical Roller Thrust Bearings Spherical roller thrust bearings are single row bearings which, due to their internal geometry, can adjust their angle to compensate shaft misalignments. Solid shaft washers and housing washers as well as steel or brass cages ensure an excellent load capacity. Spherical roller thrust bearings are able to take up radial forces and are suitable for higher speeds. 12

13 紧定套 紧定套用于将带锥孔 ( 锥度为 1:12 和 1 :30) 的圆柱 球面和双列球面滚子轴承固定在轴上 此外, 可以用紧定套调整每个轴承的径向游隙 这允许轴径具有较大公差 Clamping Sleeves Clamping sleeves are used to fix cylindrical, spherical and spherical roller bearings double row with tapered bore (taper 1:12 and 1:30) on shafts. In addition, the radial clearance of each bearing can be adjusted by using clamping sleeves. This allows larger tolerances of the shaft diameter. 退卸套 退卸套用于配合锥型孔 ( 锥度分别为 1:12 和 1:30) 的圆柱滚子轴承 单列和双列球面滚子轴承固定在圆柱轴上 滚动轴承靠在轴肩上, 用相应工具将退卸套压入锥型孔中 根据 DIN5416 标准, 退卸套为适用于轴径 480mm 以下的标准件 Withdrawal Sleeves Withdrawal sleeves are used to attach cylindrical roller, single and double row spherical roller bearings with tapered bore (taper 1 :12 or 1 : 30, respectively) on cylindrical shafts.
