Bearing Units

Pillow Block Bearings

Pillow blocks bearings(plummer block housing units) are consisted of pillow blocks bearings and bearing blocks. When put into use, it’s no necessary to design another bearing box, small dimension, simple structure, be able to mount directly on the user’s design position by bolts, convenience in usage. Bearing blocks are the integral structure, has big loading capacity, high stiffness, bearing and bearing blocks can be interchanged, means that one type bearing block can be matched with all types bearing and one type bearing can also be matched with all types bearing blocks. Pillow blocks bearing can work in the condition of two bearing blocks with different shafts, the max automatic adjustment angle can be 2degrees.

Product types, designs and variants of housing bearing units

Pillow block units

Seated (vertical) ball bearing units consist of a seated bearing mounted in a housing that can be bolted to a support surface. In our product range, you can find units to meet almost all requirements, including units that comply with ISO standards, North American standards or Japanese Industrial Standards (JIS)

Pillow block units

Flanged ball bearing units

The flanged ball bearing units consist of a housing-mounted housing with a housing bearing that can be bolted to the machine wall or frame. The main types are square flanged units, y bearing flanged units ,round flange bearing housing and oval flanged units.

Flanged ball bearing units

Hub unit bearing

Wheel bearing units enable the wheels to turn freely and smoothly, and also play a key role in vehicle safety. They contain precision bearings and sensors and increasingly include special coatings and greases for higher performance.
We offer a range of wheel hub unit for different vehicle types. For example, one design features double row angular contact ball bearings with matching ring and ball sets to provide the required axial clearance. A variation of this design incorporates a flange on the outer ring of the bearing, while another design has a flange on the rotating ring.

Ball transfer bearing units

Ball bearing transfer unit, also known as transfer balls, are the ideal solution for moving loads smoothly and precisely in a range of applications. Universal ball transfers can be surface mounted, recess mounted or spring loaded. The type of mounting varies depending on the application and enables small and large loads to be moved with ease. We can produce heavy duty ball transfer bearing
, miniature ball transfer bearings, nylon ball transfer units,roller ball transfer units(,roller ball transfer units) and many other types.

Ball screw support bearing units

Ball screw support units provide all the components needed to mount ball screws on machines: support units for light loads and small machines as well as ball screw support units for heavy loads and machine tool applications. Our ball screw support units offer fixed-side and support-side bearing assemblies to support the screw shaft. Ball screw support units include: angular contact thrust ball bearings, precision bearings, etc.

FAQ

Due to their internal design, ball bearings cannot usually be disassembled down to the component level; therefore, they cannot usually be refurbished.

Solid base shells are manufactured without cavities and fillers; they are stronger than hollow bases, and there are no traps for bacteria and fungi to grow. In the thermoplastic shell, the sturdy base will not break under steam or high-pressure washing. The hollow base saves material and weight to reduce costs. Some people use epoxy resin to backfill the hollow base to eliminate the trap of bacteria breeding, but this will not increase the strength, will cause the installation surface to be uneven, and water will seep between the shell and the filling material, causing cracking.

Use particularly thermally stable bearing rings, larger internal clearance (C4), specially selected lubricants that will not decompose at high temperatures, and zinc anodized flinger. There are two basic versions of our high temperature bearings. The suffix “C4HR5” represents the bearing that can withstand 400°F, and the suffix “C4HR23” represents the bearing that can withstand 450°F.

For critical applications such as pulp and paper processing, printing and packaging, material tearing can cause expensive downtime due to excessive torque and vibration.

The two biggest factors affecting the starting and running torque of the bearing are the seal design and lubricant selection. The shaft and bearing seat fit, component accuracy and surface finish, and retainer design also have some influence.

In higher speed applications, non-contact sealing devices are usually required to minimize operating torque and heat generation, so oil baffle rings and secondary sealing devices are usually required. Flowing oil lubrication systems are usually the best solution.

After proper installation, most seated bearings only need to be relubricated regularly with a small amount of grease and checked to ensure that they operate at low temperatures, quietness, and sufficient accuracy.

This depends on many factors, such as the application’s load conditions, operating speed, duty cycle, temperature, and operating environment. The technical information section of this website provides some basic information. Our engineers can help you determine more specific theoretical life calculations.

When noise and/or operating temperature increase or operating accuracy decreases, bearings should be replaced.

Lubricant of choice
Lubrication joint type or location
Sealing materials and design options
Dimensions, suitable for housing or insert
Fixing screw options
Paint the shell in any color

Too little or too much lubricant
Incorrect lubricant type
Poor bearing installation
Improper internal clearance
Excessive load and/or speed
Extreme temperature
Pollution
Movement between mounting surfaces

The noise emitted by the bearing may be caused by a combination of one or more factors, such as insufficient working clearance, excessive working clearance, changes in working clearance due to temperature, damage to the contact area, contamination, inappropriate lubricants or The raceway is damaged.

Lubricants have five basic functions for bearings:

Reduce friction
Reduce wear
Reduce temperature rise
Minimize corrosion
Seal contaminants

We do not recommend mixing grease. Mixing incompatible greases will cause the mixture to harden, preventing it from releasing any oil. Mixing incompatible greases can also soften the mixture, which releases all the oil. In either case, the mixture will not be able to properly lubricate the bearing. We strongly recommend using the same type of grease originally provided with the bearing.
