Why sell to us
Engineering and Application of Pillow Block Bearings
Pillow block bearings, also known as plummer blocks, are fundamental components in industrial power transmission, designed to provide essential support for rotating shafts while handling significant radial and thrust loads. Unlike unmounted bearings, these units consist of a mounting block (housing) and an insert bearing, allowing for straightforward installation on flat surfaces parallel to the shaft axis. The housings are typically cast iron, ductile iron, or cast steel, engineered to withstand heavy vibration and shock loads common in bulk material handling, aggregate processing, and heavy manufacturing environments. The insert bearings themselves are often self-aligning, compensating for initial shaft misalignment and reducing stress on the equipment during operation. This self-aligning capability is crucial in long conveyor runs or large air handling systems where perfect shaft alignment is practically impossible to maintain over time.
The internal geometry of the insert bearing dictates the unit's load capacity and speed rating, with options ranging from standard deep groove ball bearings for lighter loads and higher speeds to spherical roller bearings for extreme radial loads and severe misalignment. Sealing technology is another critical aspect of pillow block design, as these units frequently operate in highly contaminated environments. Advanced labyrinth seals, triple-lip contact seals, and heavy-duty flingers are employed to keep abrasive dust, moisture, and chemical contaminants away from the rolling elements while retaining the lubricating grease. Understanding the specific housing materials, insert types, and sealing arrangements is essential for evaluating the true industrial value of these mounted units. We recognize the engineering that goes into premium pillow block bearings from manufacturers like Dodge, SKF, Rexnord, and Sealmaster, ensuring our offers reflect their actual utility rather than just the raw material weight of the cast iron housings.
What we buy
Identifying and Valuing Surplus Mounted Units
When evaluating surplus pillow block bearings for purchase, we conduct a thorough assessment of the unit's specifications, condition, and manufacturer markings. The primary identifiers are typically cast directly into the housing or stamped on the nameplate, indicating the housing style, shaft size, and insert bearing type. For example, a Dodge Type E or a Rexnord SAF series plummer block carries specific dimensional and load-carrying characteristics that dictate its market value. We look closely at the bore size, whether it utilizes a setscrew locking mechanism, an eccentric locking collar, or a tapered adapter sleeve, as these features determine the unit's compatibility with various shafting standards. The condition of the housing is also critical; we inspect for any signs of hairline fractures, corrosion on the mounting feet, or damage to the grease fitting ports that could compromise the unit's structural integrity during heavy-duty operation.
Beyond the external housing, the condition of the insert bearing and its protective packaging plays a significant role in our valuation process. We prefer units that remain in their original factory boxes with intact VCI (Volatile Corrosion Inhibitor) paper or plastic wrapping, as this ensures the factory preservative grease has not degraded and the raceways remain free from atmospheric moisture. However, we also evaluate loose, unused units that have been stored properly on storeroom shelves. We carefully inspect the exposed seals for any signs of dry rot or brittleness, and we check the locking collars or adapter sleeves for completeness. Even if the outer cardboard packaging shows significant shelf wear or water damage from years of storage, the internal mounted unit often retains its full functional value. By accurately identifying the specific series, locking mechanism, and seal type, we provide offers that accurately reflect the component's true worth in the secondary industrial market.
How it works
How to Sell Your Excess Pillow Block Bearings
The process of selling your surplus pillow block bearings to us is designed to be highly efficient and completely transparent for maintenance planners and storeroom managers. To initiate a quote, simply compile a list of your excess mounted units, including the manufacturer, part numbers, shaft sizes, and quantities available. Clear photographs of the bearings, particularly showing the nameplates, housing castings, and the condition of the original packaging, greatly assist our evaluation team in providing an accurate and aggressive offer. We understand that MRO storerooms often have a mix of different brands and sizes, from small fractional-inch ball bearing units to massive spherical roller plummer blocks. Our team is equipped to evaluate entire lots, ensuring you receive a comprehensive offer for your complete surplus inventory without the need to separate items or deal with multiple buyers.
Once you accept our offer, we handle all the logistical details to ensure a smooth transaction and prompt removal of the surplus inventory from your facility. We provide payment upfront before any material leaves your dock, ensuring your company faces zero financial risk. Because pillow block bearings, especially large cast iron or steel units, can be exceptionally heavy, proper packaging is essential for safe transport. We require the units to be securely banded to sturdy pallets and shrink-wrapped to prevent shifting during transit. We arrange and pay for all freight costs, scheduling a dedicated LTL carrier or full truckload service depending on the volume of your surplus. There is no minimum lot size required; whether you have a single pallet of leftover project spares or an entire storeroom of obsolete mounted units, we are prepared to purchase your inventory and clear your valuable shelf space.

Common questions
Questions sellers ask
Do you buy pillow block bearings without their original boxes?
Yes, we purchase unused pillow block bearings even if the original factory packaging is missing or damaged. As long as the housing, insert bearing, and locking mechanisms are unused and free from corrosion, they hold significant value.
How do you value heavy cast iron plummer blocks compared to scrap?
We value plummer blocks based on their functional utility, brand, and series, not their raw material weight. A premium Dodge or SKF unit is worth substantially more as a usable industrial component than as scrap cast iron.
What information do you need to quote our surplus mounted units?
Please provide the manufacturer, complete part numbers from the housing or nameplate, shaft size, and quantity. Photos of the units and their current storage condition help us provide the most accurate offer.
Do you purchase both ball bearing and roller bearing pillow blocks?
Yes, we buy all types of unused mounted units, including standard duty ball bearing inserts, heavy-duty spherical roller bearings, and tapered roller bearing pillow blocks used in extreme load applications.
Who pays for the freight when shipping heavy pallets of bearings?
We arrange and pay for all freight costs associated with transporting your surplus bearings. We will schedule the appropriate LTL or truckload carrier to pick up the securely palletized units directly from your facility.
