The SKF PFD Y-bearing pillow block is a ready-to-mount unit that combines an insert bearing with a housing, available in cast iron or sheet steel. It supports transmission shafts where simple, self-aligning mounting is needed. MR Industrial Accessories LLC supplies this line from Miami, Florida, serving customers across the United States and in several Latin American countries, with technical help to select the right part number.
The PFD code covers SKF Y-bearings in the square flanged version. The digits that follow indicate the shaft diameter in millimeters: PFD 47, PFD 52, PFD 62 and PFD 72 are examples. A larger number means a larger shaft and, generally, a higher load capacity. The housing has fastening holes at the four corners, which allows quick installation on flat surfaces.
These units are used in many industries, from conveyor lines in food plants and cold storage to milling equipment, mixers, belts and agricultural machinery. The self-aligning design absorbs small shaft misalignments and simplifies mounting on welded or bolted structures. They are common where economical support, simple maintenance and the option to relubricate are important.
When choosing a pillow block, consider the shaft diameter, the load type (radial, axial or combined) and the working environment. Check the insert seal: lip or double lip versions suit dusty or damp conditions. Lubrication can be permanent or relubricable; for high temperatures or speeds, choose the version with a grease fitting. During mounting, align the holes and tighten the fastening screws evenly to avoid deforming the housing.
SKF Y-bearing pillow blocks can be interchanged with other brands that follow the same dimensional standard. Equivalent series usually share shaft diameters and hole spacing, but always check the housing dimensions and fastening type before replacing. MR Industrial Accessories LLC supplies the SKF brand within its pillow block range; to confirm interchangeability, compare the critical dimensions of the original unit with the replacement.

Frequently asked questions
- How do I identify the Y-bearing pillow block I need?
- Measure the shaft diameter and find the matching PFD part number. The numbers after PFD indicate that diameter in millimeters. If you are unsure, send a photo or the part number marked on the housing by WhatsApp and we will help you confirm it.
- Are SKF pillow blocks interchangeable with other brands?
- Often yes, provided they share the same dimensional standard. Check the shaft diameter, hole spacing and fastening type. To be certain, compare the dimensions of the original pillow block with the replacement or consult us with the measurements on hand.
- What lubrication do these pillow blocks require?
- It depends on the insert: some are lubricated for life, while others can be relubricated through a grease fitting. In dirty or humid environments, the version with a grease fitting and reinforced seals is preferable. Follow the manufacturer's instructions for grease type and frequency.
