Product Description


about Cylindrical roller bearings
Cylindrical roller bearings are consists of outer ring, inner ring, rollers and cage. The ring has ribs on both sides. Normally the structure of bearing is that cage, rollers and one ring build up the assembly, and another ring is separable. In special cases, cylindrical roller bearings without retainers can be formed.
* Standards：GOST/ASTM/GB
* Inner diameter (ID)：20mm-1400mm
* Outer diameter (OD)：40mm-2000mm
* Weight：0.001kg-915kg
* Structures：outer ring, inner ring, rollers and cage.
* Applications：large and medium-sized motors, locomotive vehicle, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, and lifting and transportation machinery.


The clearance of SYL standard cylindrical roller bearings meets the requirements of GB/T4604 "radial clearance of rolling
bearings".


The tolerance of SYL standard cylindrical roller bearings meets the requirements of GB/T307.1 "Tolerance of rolling bearing
radial bearing" and other standards.


The dimensional tolerance grade of SYL cylindrical roller bearings is generally made according to P0 (normal grade) and clearance according to group 0 (basic group).


The outer dimensions of SYL cylindrical roller bearings conform to GB/T273.3 "Genera plan for the outer dimensions of rolling bearing radial bearing", GB/T283 "Dimensions of rolling bearing cylindrical roller bearings", GB/T285 "Dimensions of rolling bearing double row cylindrical roller bearings", JB/T5389.1 "Rolling bearing and four row cylindrical roller bearings for rolling mills" and other regulations.


Non-standard cylindrical roller bearing     customization
Non-standard cylindrical roller bearing customization is a main part of SYL categories. It can be customized according to the customer's working conditions or the place where the bearing works. Internally we can optimize and improve the design of the cylindrical roller bearing, which can improve the loading capacity and service life of bearing.


Our SYL enables non-standard cylindrical roller bearings to operate safely and smoothly with precision roller selection and bearing raceway production, to achieve optimum bearing performance.
