Upgrade to stainless steel split housings

Our heavy-duty INOX 316 split bearing housings are specifically engineered for the effortless replacement of standard cast iron plummer block units. Designed as a direct drop-in solution, they allow you to upgrade your existing cast iron assemblies to corrosion-resistant stainless steel without modifications, eliminating the need for costly component changes and minimizing machine downtime.

Seamless integration with global bearing brands

All standard accessories, seals, and bearings from the industry’s leading global tier-1 brands will fit our stainless steel 316 split plummer blocks seamlessly. This universal compatibility ensures that your existing premium internal components can be reused or replaced with standard global market parts without any fitment issues.

Efficient Installation: Perfect for Pre-Assembled Shafts

Our innovative stainless steel split plummer block design is engineered to significantly simplify maintenance, allowing for the effortless mounting and dismounting of pre-assembled shafts. The premium EBL series consists of heavy-duty split plummer block bearing housings divided into a precision-matched cap and base. To ensure a seamless installation, each unit features two standard cast attachment bolt holes in the base, mirroring standard industrial layouts for a direct, hassle-free setup.

Maximum flexibility: A modular concept for diverse applications

Our engineered stainless steel split pillow block units are built on a versatile modular design concept, offering unparalleled flexibility for your machinery setups. This modular architecture allows for a wider choice of high-performance bearings and advanced sealing solutions, effortlessly accommodating a broad range of bearing/shaft combinations and specialized lubrication methods tailored to your exact operational needs.

High quality seals

An important advantage of Extreme Stainless steel, SPLIT plummer block bearing housings is that they can be fitted with different type of seals.

High quality seals for split plummer blocks are typically made of materials that are designed to resist wear and tear, while providing an effective barrier against dust, dirt, and other contaminants.  Double-lip seals are made of polyurethane, a wear-resistant material which has good elastic properties. The seals are split so that they are easy to fit.

Extreme Bearing offers a wide range of sealing options including oil seals, labyrinth seals or heavy-duty face to face seals. Case end covers are also available. See also our housing seal page.

Structural Integrity: The solid stainless steel 316 split plummer block bearing unit

The advanced engineering behind the Extreme Bearing stainless steel 316 split plummer block bearing unit makes it significantly more robust than conventional split housings on the market. Featuring a fully solid AISI 316 stainless steel base and reinforced, heavy-duty material surrounding the attachment bolt holes, each split plummer block bearing unit is built to withstand extreme mechanical loads. This solid-base design eliminates the hollow cavities found in weaker alternatives, preventing housing distortion and ensuring maximum structural integrity for your stainless steel 316 bearing assemblies in harsh industrial environments.

Advanced Thermal management: excellent heat dissipation

Beyond structural strength, the solid base of our stainless steel 316 split plummer block bearing unit provides an exceptional operational advantage by maximizing the direct contact area between the housing base and the machinery support surface. This large, flush contact zone ensures excellent heat dissipation, pulling thermal energy away from the core of the split plummer block bearing unit. By effectively reducing internal operating temperatures, this advanced thermal management significantly extends the service life of your high-performance bearings, premium seals, and specialized lubricants within the stainless steel 316 housing.

Food-Grade Hygiene: High-visibility blue end-caps and cover seals

To strictly comply with the rigorous safety and hygiene requirements of the food and beverage industry, our stainless steel 316 split plummer block bearing unit can be equipped with high-visibility blue plastic end caps and cover seals. The striking blue color is internationally standardized for food production areas because it is optically detectable, ensuring that any accidental material contamination can be instantly identified.

To guarantee maximum protection, each blue end cap is integrated with a heavy-duty rubber seal. This combination creates a secure barrier that prevents high-pressure washdown water, moisture, and fine food particles from penetrating the internal assembly, ensuring the highest level of food safety and bearing longevity.

Sterile and hygienic solutions: mirror-polished stainless steel 316 split plummer block bearing units

For high-end applications with the most stringent hygiene standards, we offer custom mirror-like polished plummer blocks. This ultra-smooth, high-gloss finish can be applied upon request to our entire product range, ensuring that every stainless steel 316 split plummer block bearing unit meets your exact sanitary specifications.

Why choose a polished stainless steel 316 split plummer block bearing unit?

• Eliminates Contamination Risks: The ultra-smooth surface of the polished stainless steel 316 housing eliminates microscopic crevices, preventing bacteria, mold, and fine process debris from adhering to the assembly.

• Optimized for Cleanrooms: This finish makes our stainless steel 316 split plummer block bearing unit the perfect choice for pharmaceutical, biotech, and premium food-grade environments where sterile conditions are mandatory.

• Superior Washdown Efficiency: Liquid and chemical cleaning agents glide off the polished surface effortlessly during clean-in-place (CIP) processes, preventing water pooling and ensuring flawless sanitation across all your stainless steel 316 bearing units.

Common Industry Synonyms

• Stainless steel split bearing plummer block units: Frequently used in European engineering specifications to denote heavy-duty, two-part rolling-element bearing assemblies.

• AISI 316 SPLIT pillow block units: The preferred terminology in North American markets, where “pillow block” is commonly used interchangeably with plummer block.

• INOX split cushion block: A term heavily used in French, German, and Italian industrial sectors (INOX being short for inoxydable), often referred to as a “cushion block” in specific mechanical drive applications.

• Nirosta split saddle bearing: A common regional term in Central Europe derived from the classic German stainless steel designation (Nichtrostender Stahl), combined with the “saddle” design of a split housing cap.

• Cromargan split bearing block: A materials-specific term used by specialists referencing high-grade chromium-nickel stainless steel alloy compositions.

Engineering Note: Regardless of whether your technical drawings specify an INOX cushion block, an AISI 316 split pillow block, or a standard stainless steel 316 split plummer block bearing unit, the structural dimensions, heavy-duty solid base, and standard mounting configurations remain completely identical. All versions deliver the exact same premium corrosion resistance and drop-in interchangeability.
