Parallel twin screw extrudes Tandem Bearings T4AR3075YB M4CT3075YB 30X75X112mm in stock
Tandem bearings T4AR3075YB M4CT3075YB consist of several axial cylindrical roller bearings arranged in line, A system of rings and washers matched to each other ensures that all stages of the tandem bearing are subjected to uniform load at all times irrespective of the ratio C/F. The rings and washers are made from hardened steel. Tandem bearings are predominantly fitted with standard axial cylindrical roller and bearing assemblies. The thrust cylindrical roller bearing T4AR3075YB M4CT3075YB with size 30*75*122mm, the inner diameter:30 mm, the outer diameter:75mm, the total height:122mm

Multi Stage cylindrical roller thrust bearings(Tandem bearings) has the characteristics of limited radial space, high axial forces, equal support of all the rows of rollers and long operating life, and is the ideal spindle of parallel screw extruder.
The tandem bearings provided by our institute has the following types: double rows, three rows, four rows, five rows, six rows and eight rows, we also provided bearings with shaft and sleeve barrel. Customers can have their own selections according to center distance of screws, space and load. We also accept the orders of other dimensions.
Application of tandem bearings
When using tandem bearings, the following recommendations should be adhered to:
1. Preload: 1% of the dynamic basic load rating. The dynamic basic load rating of each tandem bearing . Figures not listed will be provided by out institute on request.
2. Radial guidance: full complement cylindrical roller bearings or needle roller bearings can be used.
3. Eliminate tilting: the supporting parts must be machined to eliminate any tilting.
4. Mounting tolerances: recommended the following mounting tolerances: shaft f6 and housing bore F7.
5. Lubrication: tandem bearings must always be lubricated by oil circulation.
Tandem bearings offer an optimum solution wherever the following requirements apply:
■ small radial design envelope
■ high axial forces
■ long operating life
■ low frictional energy.
Tandem bearings have proven effective principally in gearboxes for single and twin screw extruders in the rubber and plastics industry.
Other possible applications include:
■ deep hole drilling equipment
■ friction welding machines.
We JINHANG Precision bearing are a professional
Precision bearing manufacturer in the world, established in 2005, specializing in slewing bearings, slewing drives,rotary table bearing,crossed roller bearing,cylindrical roller bearing,tapered roller bearing,spherical roller bearing,thrust roller bearing thrust ball bearing,tandem bearing,pinion and other special machine parts, with design, production, sales, marketing and service all over the world. For the high precision bearing,our precision grade can reach to P5 P4 P2 class.
Our team advantage:
We have 70 employees, with 10 experienced engineers and professional technicists. The most of Engineer from LYC and ZWZ brand factory, they had owned produce and design and after sales experienced to design the bearing.We can also design the drawing according to the bearing work condition to meet the customer requirement.
Equipped with advanced manufacturing CNC Machine and test instruments to insure the accurate tolerance , all bearings are of uniform marking and packing with superior quality, reasonable prices and perfect services. Meanwhile we can make the module to test the mounting hole.
All the bearing from the forging to assembly process,It will need to inspect step.For the bearing forging we will need to test the size and hardness and surface, for the lathe process and grinding process,first it will need to check by the worker ,and then the professional inspector will checking the size and accurate,The last step the monitor will inspect the size. It can insure zero defect.
