 Double-row cylindrical roller bearings are available in two types, NN and NNU, and two series, 30 and 49.The rollers in the NN type bearing are guided by the ribs of the inner ring. The rollers in the NNU type bearing are guided by the ribs of the outer ring.
Bearings are available with either a tapered bore type (which allows adjustment of radial internal clearance of bearing) or a standard cylindrical bore. The bearings come in two types, standard type and high-speed HS type. Standard cage is machined brass.

NNU40/500MAW33 main spindle cylindrical roller bearing specification as following:

Cylindrical roller bearing application as following:

Cylindrical roller bearings are used in a variety of applications. Examples include mining, petroleum production, power generation, power transmission, cement processing, aggregate crushing, and metal recycling. Some cylindrical roller bearings are used in briquetting machines, rubber mixing equipment, rolling mills, rotary dryers, or pulp and paper machinery. Others are used in construction equipment, crushers, electric motors, blowers and fans, gears and drives, plastics machinery, machine tools and traction motors and pumps.

Why choose JHB bearings
Who we are?
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.

Manufacturing ability:
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.
Quality control:
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.
Service:
It can calculate the load curve.
Can offer assembly drawing based on the bearing working condition
Can offer pre- sale ,sale and after sale service
