NNU4938MAW33 two row cylindrical roller bearing 190x260x69mm,brass cage for Hoists

Two-row cylindrical roller bearing  NNU4938MAW33 has additional radial load-carrying capability compared to single row cylindrical roller bearing.It designed to ISO Specified interchangeable dimensions. Sold as complete assembly.

The cylindrical roller bearings NNU4938MAW33 has outer rings with solid ribs and lubrications grooves and holes on outer rings, one solid brass cage

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 typebearing 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

Full-Complement (NCF)
The full-complement (NCF) single-row bearings include integral flanges on the inner and outer rings. These bearings also can manage axial loads in one direction and permit small axial
displacements.
TWO-ROW BEARINGS
Two-row, or double-row, cylindrical bearings offer added radial capacity over tradition one-row types. These bearing types are interchangeable so the dimensions and diameter under the rollers (NNU style) and diameter over the rollers (NN style) are held to an ISO/DIN standard. The standard cage design is a drilled pocket, finger-style retainer
FOUR-ROW BEARINGS
Four-row cylindrical bearings have an extremely high radial load capacity, but no thrust capacity. This bearing type is mostly used in roll neck and work roll applications in the metal rolling industry. Straight and tapered bore designs are available.

 

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
