MOLINE BEARING
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.
