11 best mounted cartridge block bearings

Mounted cartridge block bearings are an essential component in various industrial and mechanical applications, providing support and enabling the smooth rotation of shafts. Here's what you need to know about mounted cartridge block bearings:

Design and Purpose:
- Mounted cartridge block bearings, often referred to as pillow block bearings, are designed to support a rotating shaft while allowing it to move linearly or pivot. They are commonly used to provide support and maintain the alignment of rotating equipment such as conveyor belts, fans, pumps, and other machinery.
Construction:
- These bearings consist of two main components: the bearing housing or cartridge block and the bearing insert (usually a ball or roller bearing). The housing is typically made of cast iron, stainless steel, or thermoplastic materials, and it houses the bearing insert.
Mounting Options:
- Mounted cartridge block bearings come in various designs to suit different applications. The most common mounting options include:
  - Set-screw: Bearings with set screws that tighten against the shaft to secure it in place.
  - Eccentric locking collar: Bearings with an eccentric collar that grips the shaft tightly when rotated, providing a secure fit.
  - Adapter sleeve: Bearings that use an adapter sleeve to fit different shaft sizes, allowing for easy installation and removal.
Sealing and Lubrication:
- Many mounted cartridge block bearings come equipped with seals or shields to protect the bearing and lubrication from contamination, moisture, and dust.Proper lubrication is crucial to reduce friction, heat, and wear in the bearing, extending its lifespan.
Alignment and Adjustment:
- Pillow block bearings are adjustable to ensure proper shaft alignment. This adjustability is essential for preventing premature wear and ensuring efficient operation. Misalignment can lead to increased friction and reduced bearing life.
Load Capacity:
- The load-carrying capacity of mounted cartridge block bearings varies depending on their size, design, and materials. It's essential to select a bearing that can handle the expected radial and axial loads in your application.
Maintenance:
- Regular maintenance is necessary to ensure the continued performance of mounted cartridge block bearings. This includes checking for wear, lubricating as needed, and addressing any issues with alignment or sealing.
Application Areas:
- Pillow block bearings are used in a wide range of industries, including manufacturing, agriculture, mining, and construction, where they are employed in conveyor systems, machinery, and various mechanical drives.
Environmental Considerations:
- When selecting mounted cartridge block bearings, consider the operating environment, including temperature, humidity, and exposure to chemicals or contaminants, to choose the appropriate materials and seals.

In summary, mounted cartridge block bearings, also known as pillow block bearings, are essential components in industrial and mechanical systems, providing support and alignment for rotating shafts. Selecting the right type and maintaining them properly is crucial for the efficient and reliable operation of machinery and equipment.

User questions & answers

Question:	What is The over all width of the mounting base please
Answer:	That would depend upon the diameter and length of the specific rods you ordered and upon the means by which they're mounted on your cart. If the rods are attached to the cart by their ends and to a single wheel in the middle, then you should expect some nasty destruction before all is over. If, on the other hand, you can keep all the strains in shear by situating your rod mounts immediately adjacent to the wheel(s), then you stand a far better chance of making it work. It would be a travesty to use rods like this for sucha purpose, though, unless you have a most excellent reason to use highly precise, extremely straight, and finely polished rods as axles. Hint: there are exceedingly few good reasons in this world to do that. Chances are very good that you would do a fine job with some nasty stick of galvanized round rod you found in the alley behind your own local hardware store.
Question:	are these for a 1" diameter shaft? will a 1" diameter rod fit in the hole
Answer:	You can thread them all day long with a lathe if you like, but first you have to remove the chrome (chemically or with abrasives) and anneal the section of the rod that you need to thread. Otherwise, you'll need to grind the threads with silicon carbide or diamond.
Question:	will this work as go kart axle bearings
Answer:	Thans for your question. We check it again, it is indeed our mistake. Its straightness number should be straightness be below 5μm/100mm. We have upated this data on our page.
Question:	What’s the measurement between the mounting holes
Answer:	On the picture is the product display. The actual delivery length is 400mm

User questions & answers

Question:	The dimensions shown here do not make sense. i.e. - 95mm is not 4 3/4" etc. which one is right? mm or inches
Answer:	I’m not at home to measure the block, but I’d say 4 3/4” is about correct for the overall width, not 95mm.
Question:	What is the max rpm
Answer:	There was no MDS or white paper delivered with the blocks, so I cannot confirm. My application was for a low rpm project. The steel bearing in the pillow block seems to be fairly decent quality, but likely not to exceed 5000 rpm

User questions & answers

Question:	Do you have an .pdf for installation? I noticed the bearing are not square to the housing. I assume that is intentional for a reason
Answer:	These pillarblock bearings have floating bearings, so if you mount them a little off square, they will still run true to the next bearing on the axle.

Cast Iron Pillow Block Mounted Bearings - 3/4" inch Inside Diameter w/Set Screw Lock 4psc of ucp204-12

DEEPDREAM

Based on 86 reviews Check latest price

Product description

The UCP204-12 pillow block mounted bearing with a 3/4" inside diameter, two bolt holes, and a set screw lock is designed for mounting onto bearing surfaces parallel to the shaft axis, such as conveyor belts.

This ready-to-mount unit has a cast iron housing, chrome steel bearings, and is designed for efficient operation at a wide range of speeds.

The bearing has a dynamic (radial) load rating of 12.8 kN and a static (axial) load rating of 6.65 kN.

This one-piece pillow block housing allows for a stationary outer ring and rotating inner ring.

The bearing is secured to the shaft with set screws to prevent slippage and the housing requires two 3/8” bolts (sold separately).

This mounted bearing is used in industrial manufacturing, food and beverage manufacturing, and in the textile industry.

Mounted bearings combine a bearing mounted inside a housing unit.

The bearing housing replaces the need for a casting or weldment to position the bearing securely for reliable operation, and its design determines the type of insert bearing.

Insert bearings use rolling elements (ball, cylindrical, spherical, barrel, needle, spindled, or tapered) to maintain the separation between moving parts to reduce rotational friction, and to support radial and axial loads.

Available in a variety of materials and mounting configurations, mounted bearings can be one- or two-piece, they can have an extended inner ring and locking device, and they can have seals and end caps that retain lubrication and protect the working parts of the bearing from environmental debris.

Mounted bearings support shafts in a variety of mounting configurations (flange block, hanger, pillow block, and take-up block), and are used in a range of applications from light duty shaft guidance on conveyors to road building equipment and crushers.
