调心滚子轴承

在容易发生错位或轴挠曲的应用中，需要处理非常重的径向和轴向载荷？使用球面滚子轴承来应对挑战，其高承载能力和适应错位的能力可帮助您降低维护成本并延长轴承使用寿命。这是当今行业中最广泛的轴承 - 既有开式轴承也有密封式轴承。产品系列包括专为许多应用而设计的球面滚子轴承，包括风力涡轮机主轴、连铸机、振动应用和高速应用，以及带固体油的轴承、剖分式轴承、滚子轴承单元，以及适用于最恶劣操作环境的三重防护解决方案。

Spherical roller bearings

Dealing with very heavy radial and axial loads in applications prone to misalignment or shaft deflections? Meet the challenge with spherical roller bearings, whose high load carrying capacity and ability to accommodate misalignment help you obtain low maintenance costs and long bearing service life. this is the widest in the industry today – both open and sealed. assortment includes spherical roller bearings designed for many applications, including wind turbine main shafts, continuous casters, vibratory applications and high-speed applications, as well as bearings with Solid Oil, split bearings, roller bearing units, and, for the harshest operating environments, three-barrier solution.

球面滚子轴承的品种是市场上最广泛的。标准品种包括：

CC、CA 和 E 设计轴承

密封轴承

特定用途轴承

球面滚子轴承，连铸机应用除外。几乎所有轴承都可选配锥形孔。根据轴承系列，锥形孔有：

锥度1:12（型号后缀 K）

锥度1:30（型号后缀 K30）

The assortment spherical roller bearings is the widest available on the market. The standard assortment includes:

CC, CA and E design bearings

sealed bearings

application specific bearings

Spherical roller bearings, except those for continuous caster applications. Almost all bearings are available with the option of a tapered bore. Depending on the bearing series, the tapered bore has:

a taper 1:12 (designation suffix K)

a taper 1:30 (designation suffix K30)

*CC 设计轴承

具有两个冲压窗式钢保持架、一个无法兰的内圈和一个以内圈为中心的浮动导向环

在产品表中以型号后缀C 或 CC 表示

在产品表中以型号后缀EC 或 ECC 表示（用于较大的轴承）并具有优化的内部设计以提高承载能力

*CA 设计轴承

具有机加工的双叉型黄铜保持架、两侧带有保持法兰的内圈和一个以内圈为中心的浮动导向环

内圈上的法兰用于在安装或维护期间旋转轴承时将滚子保持在适当位置，不用于引导滚子或承受任何轴向载荷。

在产品表中以型号后缀CA 表示

在产品表中以型号后缀ECA 表示，用于较大的轴承，并具有优化的内部设计，可提高承载能力

*E 设计轴承

具有两个冲压窗式钢保持架、一个无法兰内圈和一个浮动导环，该导环以内圈(d ≤ 65 毫米) 或保持架 (d > 65 毫米) 为中心

在产品表中以型号后缀E 表示

具有优化的内部设计，可提高承载能力

保持架

有关保持架适用性的信息，请参阅保持架。

环形槽和润滑孔

CC 和 CA 设计轴承在外圈上带有环形槽和三个润滑孔（型号后缀 W33）或在外圈上带有三个润滑孔（型号后缀 W20）。

E 设计轴承标准配置为环形槽和三个润滑孔。此特征未在轴承型号中标识（无型号后缀）。

外圈上的密封槽

也可密封的开式轴承可能在外圈侧面有凹槽。

*CC design bearings

have two stamped window-type steel cages, an inner ring without flanges and a floating guide ring centred on the inner ring

are indicated in the product table by the designation suffix C or CC

are indicated in the product table by the designation suffix EC or ECC for larger bearings and have an optimized internal design for increased load carrying capacity

*CA design bearings

have a machined double prong-type brass cage, an inner ring with a retaining flange on both sides and a floating guide ring centred on the inner ring

The flanges on the inner ring are designed to keep the rollers in place when swivelling the bearing during mounting or maintenance and are not designed to guide the rollers or accommodate any axial load.

are indicated in the product table by the designation suffix CA

are indicated in the product table by the designation suffix ECA for larger bearings and have an optimized internal design for increased load carrying capacity

*E design bearings

have two stamped window-type steel cages, an inner ring without flanges and a floating guide ring centred on the inner ring (d ≤ 65 mm) or on the cages (d > 65 mm)

are indicated in the product table by the designation suffix E

have an optimized internal design for increased load carrying capacity

Cages

For information about the suitability of cages, refer to Cages.

*Annular groove and lubrication holes

CC and CA design bearings are available with an annular groove and three lubrication holes in the outer ring (designation suffix W33) or three lubrication holes in the outer ring (designation suffix W20) .

E design bearings have an annular groove and three lubrication holes as standard. This feature is not identified in the bearing designation (no designation suffix).

Seal grooves in the outer ring

Open bearings that are also available sealed may have recesses in the outer ring side faces.
