The SEALMASTER ERPB line covers mounted pillow block units built to carry rotating shafts in industrial machinery. They suit applications where the load acts mainly in the radial direction and where a sturdy unit that is simple to install and align is preferred. MR Industrial Accessories LLC supplies this series to customers throughout the United States and Latin America. If you are unsure which model fits your equipment, send the part number or the shaft dimensions by WhatsApp or email and our team will help you choose.

Reading the code: ERPB identifies a family of pillow block housings supplied with the bearing already incorporated. The digits that come after the letters set the size and the housing configuration, so ERPB-112-2, ERPB-115-2 and ERPB-200-2 each correspond to a different shaft size and capacity. The -2 ending typically marks a construction variant inside the series, for instance the sealing arrangement or the housing shape. Because the code carries this much information, confirming each part number against the manufacturer's dimension table is the safest route; you can also send us the exact model and we will review it with you.

Where they are used: these units appear in food processing plants, material handling systems, mills, bottling lines, conveyors and agricultural equipment, among other operations. The pillow block format lets you bolt the housing to a metal structure or a concrete base, which makes shaft alignment easier and lets the unit absorb radial loads. As a mounted assembly, it also cuts assembly work, since there is no need to fit a separate housing around a conventional bearing.

Choosing the right unit: start with the shaft diameter, then look at the radial load and the conditions around the equipment. ERPB housings can be supplied with seals that keep dust and moisture out, so check which sealing type matches your environment. Correct alignment during mounting matters, because misalignment adds stress to the unit. Lubrication and proper tightening of the set screws also play a large part in how long the housing lasts. On equipment that vibrates, additional fasteners are worth considering.

Interchange and replacement: ERPB housings can be swapped for equivalent products from other brands as long as the key dimensions line up, namely shaft diameter, the distance between the mounting holes and the height to center. Check those dimensions before you pull a unit out of service. Our team can point you to the option that fits your application without any modification to the existing structure; just send the original housing part number and we will indicate the right match.
