How to solve inflexible rotation problem of conveyor roller?

To ensure accuracy during conveyor roller manufacturing process 
Such as the inner hole precision of punch bearing housing should reach grade 3, dimensional tolerance,coaxial degree and ovality of the pipe body two ends must conform to the national standard,can not exceed the tolerance.
Sealing and lubrication
in addition to ensure the quality of manufacture, also require better lubrication materials, such as lithium base grease which can improve the bearing lubrication performance, this is very necessary to prolong the service life of roller.
Bearing seat adopts labyrinth seal structure of centripetal ball bearing supporting and plastic sealing ring, which can guarantee reasonable bearing stress of roller during operation,but also ensure good dust prevention effect, small resistance, and convenient installation and easy maintenance, it can effectively reduce the conveyor operation cost at the same time. 

Introduction of Motor IP Grade: The meaning of the second number

0: no special protection
1: drip-proof: vertical drop of water will not directly enter into the motor.
2:15 degrees angle drip proof: within a range of 15 degrees angle, water drop will not directly enter into the motor.
3: 60 degrees angle water spray proof: within a range of 60 degrees angle, water-spray will not directly enter into the motor.

4: water splash proof: splash water in any direction will not bring harmful effects to motor.
5: water spray proof: spray water in any direction will not bring harmful effects to motor.
6: water waves or strong water spray proof: furious waves or strong water spray will not bring harmful effects tomotor.
7: water immersion proof: motor immersed in the water under a stipulated pressure and time, the water inflow will not bring harmful effects.

Introduction of Motor IP Grade :The Meaning of First Number

Motor IP (INGRESS PROTECTION) grade system is drafted by IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION ).IP grade is composed of two numbers, the first number represents for anti-invasion grade of external objects and dust, the second the number shows that the sealing degree of anti- invasion of moisture and water, if the number is greater, the degree of protection will be higher.
0: no special protection
1: it can prevent external objects with solid diameter larger than 50 mm entering into the casing.
2: it can prevent external objects with solid diameter larger than12 mm entering into the casing.
3: it can prevent external objects with solid diameter larger than 2.5 mm entering into the casing.
4: it can prevent external objects with solid diameter larger than 1 mm entering into the casing.
5: protection against dust, it can prevent dust from entering to affect the normal operation of the product, and prevent dust contacting the inner casing or parts.
6: sealing against dust, it can completely prevent dust from entering into the casing and prevent the dust contacting the inner casing or parts.
