1600 series bearings

1600 series bearings

The letters on the deep groove ball bearing model are generally followed by ZZ or 2Z, RS or 2RS
It means the dust cover (ZZ) and the sealing cap (2RS) for the bearings. ZZ stands for steel plate dust cover, which is usually applied to: 1. the external environment is better; 2.suitable for high-speed operation occasions.
2RS means rubber sealing ring, the sealing property of contact is good, suitable for: 1. the external environment is relatively bad situation; 2. start the general situation of speed.

Feature

The Inch bearings are suitable for all kinds of inch sized industrial machines, small rotary machines and so on;
In order to obtain the low friction torque, high rigidity and good rotary precision of the bearing, the steel ball with small outer diameter is used.
The use of hollow shafts ensures lightweight and wiring space.
Recently, the demand for miniaturization, light weight and thin wall type of these bearing devices has increased.

Application

Micro motor testing instrument
Office apparatus, stepping motor
Medical equipment,robot
Optical imaging apparatus deceleration transmission device
Stepping motor, medical instrument, testing instrument
Optics – imaging instruments; rotary encoders
