NSK bearing 699ZZ

NSK bearing 699ZZ

Product structure Type and characteristics:

Single row deep groove ball bearings - dust cover ball bearings and sealing ring ball bearings, sealed with an appropriate amount of high-quality lubricating grease. Compare the characteristics of sealed ball bearings as shown in the following figure:

Product Categories:

(1) Full ball bearings, due to the design of filling ports on the inner and outer rings, can accommodate more balls than deep groove ball bearings. Due to the presence of a filling port, it is not suitable for applications with high axial loads. In addition, when using bearings, try to use the ball filling position of the outer ring as a non load ring as much as possible. The holder is a stamped holder.

(2) Magnetic motor ball bearings have slightly shallower inner ring grooves than deep groove ball bearings, and one side of the outer ring has a tapered hole that can be separated, making it easy to install the bearing.

Product Parameters:

Precautions for using deep groove ball bearings:

Deep groove ball bearings, when the axial load is too small during operation, can cause sliding between the ball and the raceway, leading to scratches. Especially large deep groove ball bearings with heavy ball and cage weights tend to have this tendency. It is expected that there may be situations where the bearings are too small during use.
