Deep Groove Ball Bearings of the series 69

Special feature of this series: Main dimensions according to DIN 625-1. Thin section bearings of the 69 series have considerably smaller dimensions than deep groove ball bearings of the 60, 62, 63 and 64 series with their thincross section at the same inside diameter. Relatively high shaft- and axis diameters can thereby be installed at an also extremely confined installation space. They are extremely light and are suitable for comparatively high speeds.

Internal clearance: A standard internal clearance (CN) is suitable for the operation of the bearing in case of ordinary temperatures and for customary fits. An increased internal clearance (C3) is recommendable in case of high temperature gradients between the rings or in case of fixing the bearing through a press fit. | more

Seals: Rubber seals (RS/2RS) have the optimum sealing action with increased friction. Metal seals (Z/ZZ) are suitable for higher speeds, but they have a limited sealing action as they seal contactless. Open, seal-less bearings are suitable for extremely high speeds and - furthermore - they can be regreased more easily. However, they are more susceptible to soiling. | more

Special design of the ball bearing

Maximum permissible load capacity of the bearing based on the materials used and the geometric design.

Noise level of the bearing during operation.

Smooth-running bearings have low frictional resistance.

Resistance of the materials used in the bearing to water and other corrosive media.

Maximum permissible speed of the bearing.

Protection of the bearing from the ingress of foreign particles and liquids.

Highest ambient temperature at which the bearing can be used without restrictions

Lowest ambient temperature at which the bearing can be used without restrictions

Accuracy of main dimensions (inner diameter, outer diameter and width). P0 is the standard tolerance class, P6 and especially P5 are a bit more precise.

The bearing clearance is the amount by which the two rings of a non-installed roller bearing can be displaced in relation to one another. There are different internal clearance classes. CN is "normal internal clearance" and is the best choice for many applications. C3, C4, ... indicates increased clearance. C2, C1, ... stands for reduced clearance.

Type of sealing of the bearing to protect it from contamination.

Inner and outer ring material

Material of the rolling element (i.e. the balls or rollers)

Material of the cage (the cage holds the rolling elements in place)

Material from which the bearing seal is made.

Type of lubrication of the rolling bearing. Rolling bearings are usually either greased, oiled or dry.

Some materials used for rolling bearings are magnetic.
