Description

The BOWER EPB series pillow block housing is a cast iron unit that holds a bearing with its shaft running parallel to the mounting surface. It bolts down to a horizontal base and secures the bearing through an eccentric locking collar. This makes it a stable, serviceable choice for drive equipment in plant environments.
Reading the EPB code is straightforward. The letters stand for the housing type; the first digit tells you how many mounting bolts it uses; the remaining digits give the housing size. So EPB2-107 is a two-bolt housing sized for a 1 7/16" shaft, and EPB4-215 is a four-bolt version for a 2 15/16" shaft. That structure lets you match mounting and shaft diameter quickly.
You will find these housings on belt conveyors, bucket elevators, mixers, mills, and other process equipment in food, cement, mining, and material handling. Their flat base mounts easily on steel or concrete. In dusty or damp settings, the right seal choice matters as much as the housing itself.
Selection comes down to shaft diameter, radial load, and load direction. During installation, align the housing with the shaft and set the eccentric collar to suit rotation direction. Use the lubricant specified for the housed bearing, and pick sealing based on contamination level. A level base and correctly torqued bolts help prevent vibration and early wear.
Type E pillow block housings interchange across brands when the mounting standard and key dimensions match. For a replacement, compare bolt spacing, shaft center height, and housing diameter. If you have another brand's part number, our team can point you to the equivalent so the swap is direct.

Frequently asked questions
- What does the designation EPB2-107 mean?
- EPB identifies a type E pillow block housing. The 2 means two mounting bolts, and 107 is the housing size for a 1 7/16 inch shaft. Other part numbers in the series follow the same pattern.
- How do I choose between a two-bolt or four-bolt housing?
- It depends on the load and the space available. Four-bolt housings give more stability under high loads or vibration. Two-bolt housings are easier to mount in tight spots. Always check hole spacing and center height.
- What bearing does the EPB housing take?
- The EPB housing accepts bearings with an eccentric locking collar, as used in the Type E line. To identify the exact bearing, send us the housing part number or shaft dimensions and we will quote the complete assembly.
