Double row deep groove ball bearings types 双列深沟球轴承类型

深沟球轴承

深沟球轴承是最广泛使用的轴承类型，用途特别广泛。它们摩擦力小，经过优化，噪音小、振动小，可实现高转速。它们可承受两个方向的径向和轴向载荷，易于安装，并且比其他类型的轴承需要更少的维护。

Deep groove ball bearings

Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.

*双列深沟球轴承

当需要更高的承载能力时，这种双列设计是单列深沟球轴承的良好替代品。

*Double row deep groove ball bearings

This double row design is a good alternative to single row deep groove ball bearing when higher load carrying capacity is needed.

双列深沟球轴承非常适合单列轴承承载能力不足的轴承配置。对于相同的内孔和外径，双列轴承比62 和 63 系列的单列轴承略宽，但承载能力要高得多。

双列深沟球轴承仅提供开式轴承（无密封件或防尘罩）。

保持架

双列深沟球轴承配有两个卡扣式、球心玻璃纤维增强 PA66 保持架（型号后缀 TN9）。

在高温下使用时，某些润滑剂会对聚酰胺保持架产生不利影响。

Double row deep groove ball bearings are very suitable for bearing arrangements where the load carrying capacity of a single row bearing is inadequate. For the same bore and outside diameter, double row bearings are slightly wider than single row bearings in the 62 and 63 series, but have a considerably higher load carrying capacity.

Double row deep groove ball bearings are only available as open bearings (without seals or shields).

Cages

double row deep groove ball bearings are fitted with two snap-type, ball centred glass fibre reinforced PA66 cages (designation suffix TN9).

When used at high temperatures, some lubricants can have a detrimental effect on polyamide cages.
