The importance of bearing seals

Sealing parts are extremely important for bearings. If there is a problem in the sealing part, the pressure on the bearing sealing test is very high, especially for the pressure test without a rod cavity. As a result, this type of pressure test is usually carried out after carefully assembling the cylinder before entering the commissioning stage of the assembly machine. The bearing sealing test is based on the assembly and reliability assessment of the seal part and joint of the assembled cylinder, such as cylinder nozzle sealing and connection, cylinder piston up, static seal and sealing condition, etc.

The main products are inside diameter 2MM - 120MM sealed dustproof stopper groove ball series

Built-in precision ball institutions, when the torque exceeds the set value of the moment, so that the active and passive driving off, the reaction time :1-3 ms
Disengagement torque through the dial within a certain range for stepless adjustment, torque accuracy, responsive, safe and reliable;
Disengage momentary overload electrical signal output
24V DC control power transmission through the separation and pull, pull power, power separation
Shaft - Flange (Round) structure, customers can install their own pulleys, sprockets, gears and other components
Used dry, oil-free environment, the reaction time is sensitive, easy to achieve high clutch, switch
Single friction plate structure, can pull in high-speed rotation or separation
Easy installation type, the angular contact ball bearing is almost no preparation other accessories for easy installation directly
Built-in precision ball institutions, when the torque exceeds the set value, the drive side and load side fully disengaged
Response time: 3 ms, safe and reliable mechanical overload protection device
Adopt flexible coupling, both sides of the shaft hole (optional keyway, spline, expansion sets)
Overload disengagement torque adjustable. Momentary overload electrical output signal for alarm or automatic shutdown
