About MOLINE BEARING

Moline Bearing is a manufacturer of mounted bearing units and related power-transmission components, with a product history that includes cast iron housed bearings for industrial applications. The brand's catalog covers flange-mount, pillow block, and take-up units, with a focus on spherical roller bearing designs that accommodate misalignment and shaft growth. These units are used in conveying, material handling, and process equipment where radial and axial loads must be supported under continuous operation. 3G Electric supplies Moline Bearing products globally, offering technical selection support and logistics coordination for maintenance, repair, and operations (MRO) and original equipment manufacturer (OEM) requirements.

The Moline Bearing line includes expansion pillow block spherical roller bearings, such as the SKU 836UJ2, which features a cast iron housing with four mounting holes and a 3/4 in mounting bolt size. This design allows for axial movement to compensate for thermal expansion in rotating shafts. Flange-mount spherical roller bearings are also available, including models with cylindrical bores ranging from 1-1/2 in to 3 in, cast iron not-split housings, and locking mechanisms such as concentric collars or set screws. These units are pre-lubricated with LC-2 lithium complex grease or lithium complex grease, depending on the model, and are designed for mounting bolt sizes from 7/16 in to 1/2 in. The bearings are suitable for applications requiring support of rotating shafts in industrial machinery, with maximum speeds up to 1,200 RPM for certain expansion pillow block units.

Technical buyers should note that Moline Bearing housed units are constructed with cast iron housings, which provide rigidity and load-bearing capacity. The spherical roller bearing design accommodates misalignment between the shaft and housing, reducing stress on components. Flange-mount units feature four mounting holes for secure attachment to structures, and the not-split housing design simplifies installation and replacement. The use of lithium complex grease supports operation across a range of temperatures and loads. 3G Electric maintains inventory of Moline Bearing products and can assist with cross-referencing part numbers, confirming bore sizes, and arranging shipments to international destinations. For plant engineers and maintenance managers, this means access to replacement bearings that match original specifications, helping to minimize downtime and maintain equipment reliability.

Common Applications

  • Bulk material handling conveyors — Moline Bearing expansion pillow block spherical roller bearings (e.g., SKU 836UJ2) accommodate shaft growth and misalignment in head and tail pulleys.
  • Industrial fans and blowers — Flange-mount spherical roller bearings (e.g., SKU 836U15) support rotating shafts where radial loads and moderate axial loads are present.
  • Mixers and agitators — Moline Bearing flange-mount units with concentric collars (e.g., SKU 836U21) provide secure shaft locking in mixing equipment.
  • Screw conveyors — Expansion pillow block bearings (e.g., SKU 836UJ2) allow for thermal expansion in screw conveyor shafts handling bulk solids.
  • Pumps and process equipment — Flange-mount spherical roller bearings (e.g., SKU 836TD1) support pump shafts in chemical and petrochemical plants.
  • Packaging machinery — Moline Bearing flange-mount units (e.g., SKU 836TW0) are used in conveyor and drive systems where reliable shaft support is required.

Frequently asked questions

Common questions about MOLINE BEARING from 3G Electric.

What is the difference between Moline Bearing expansion pillow block and flange-mount spherical roller bearings?

Moline Bearing expansion pillow block spherical roller bearings, such as SKU 836UJ2, are designed to accommodate shaft growth and misalignment in pillow block configurations. They feature a cast iron housing with four mounting holes and allow axial movement. Flange-mount spherical roller bearings, such as SKU 836U15, are mounted to a surface perpendicular to the shaft and use a concentric collar or set screws for shaft locking. Both types use spherical roller bearings to handle radial and axial loads, but the mounting orientation and expansion capability differ. Selection depends on the application's space constraints and whether thermal expansion compensation is required.

What bore sizes are available in Moline Bearing flange-mount spherical roller bearings?

Moline Bearing flange-mount spherical roller bearings are available in cylindrical bore sizes including 1-1/2 in, 2 in, 2-3/16 in, 2-7/16 in, 2-3/4 in, and 3 in. These units feature cast iron not-split housings and are pre-lubricated with LC-2 lithium complex grease or lithium complex grease. Mounting bolt sizes range from 7/16 in to 1/2 in, depending on the model. The bearings are designed for four-bolt flange mounting and use either concentric collars or set screws for shaft locking. For specific bore and mounting requirements, consult the product specifications or contact 3G Electric for assistance.

What lubricant is used in Moline Bearing mounted units?

Moline Bearing mounted units are pre-lubricated with LC-2 lithium complex grease or lithium complex grease. For example, SKU 836U15, 836U21, 836TD1, 836TW0, 836TT6, and 836TR7 use LC-2 lithium complex grease, while SKU 60JP63 uses lithium complex grease. These greases are suitable for industrial applications and provide lubrication across a range of operating temperatures and loads. The pre-lubrication simplifies installation and reduces maintenance requirements. When replacing or relubricating, use a compatible lithium complex grease to maintain performance and avoid grease incompatibility issues.

What is the maximum speed for Moline Bearing expansion pillow block spherical roller bearings?

The Moline Bearing expansion pillow block spherical roller bearing, SKU 836UJ2, has a maximum speed of 1,200 RPM. This rating applies to the specific unit with a 3-15/16 in bore and cast iron housing. Maximum speed can vary depending on the bearing size, load, and operating conditions. For other Moline Bearing models, refer to the product specifications or consult 3G Electric for application-specific guidance. Operating within the rated speed helps ensure bearing life and reliability.

Are Moline Bearing housed units available with split or not-split housings?

Moline Bearing flange-mount spherical roller bearings in the supplied product list feature not-split cast iron housings. For example, SKU 836U15, 836U21, 836TD1, 836TW0, 836TT6, and 836TR7 all have not-split housings. Not-split housings provide a rigid structure and are typically used where the shaft can be inserted through the bore during assembly. Split housings, which allow installation around an existing shaft, may be available in other Moline Bearing series. For specific housing configurations, verify the part number and specifications or contact 3G Electric for assistance.

How does 3G Electric support Moline Bearing product selection and procurement?

3G Electric supplies Moline Bearing products globally and provides technical support for selection and procurement. This includes assistance with cross-referencing part numbers, confirming bore sizes, mounting configurations, and lubricant specifications. 3G Electric can also coordinate logistics for international shipments, helping maintenance and procurement teams obtain replacement bearings that match original equipment requirements. For application-specific questions, such as load capacity or speed limits, 3G Electric can provide product data and facilitate communication with the manufacturer. The goal is to streamline the procurement process for industrial bearings and related components.
