Description
SKF PHF SF-40MM belongs to taper bushings and components, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for PHF SF-40MM and any equivalents.
The SKF PHF SF taper bushing is a fastening component designed to secure pulleys, gears, couplings and other transmission elements onto cylindrical shafts. Its tapered design creates a firm, centered connection when bolted against the mounted element, transmitting torque through friction. This makes it a practical choice for assembling and disassembling power transmissions in industrial settings. MR Industrial Accessories supplies it as part of its power transmission product line.
The part number PHF SF-…MM follows a clear pattern. PHF denotes the SKF taper bushing family for axial mounting. SF refers to the fastening variant that uses front screws. The …MM suffix indicates the shaft diameter in millimeters for which the bushing is machined. For instance, PHF SF-40MM fits a 40 mm shaft, PHF SF-42MM fits a 42 mm shaft, and the same logic applies to PHF SF-48MM, PHF SF-55MM, PHF SF-60MM and PHF SF-65MM. This coding lets you pick the right bushing based on shaft size without needing extra adapters.
These bushings appear in many industrial settings: mounting V-belt pulleys, chain sprockets, flexible and rigid couplings, and impellers in conveying equipment. They are common in food processing, cement, mining, paper and water treatment plants. In production lines, conveyor belts, mixers and centrifugal pumps, they provide a removable, high-strength joint between the shaft and the transmission element.
When selecting a taper bushing, consider the shaft diameter, the torque to be transmitted and the hub dimensions of the element to be mounted. To install, insert the bushing into the hub, align the holes and tighten the screws progressively in a cross pattern to ensure even centering. Clean the tapered surfaces, check for burrs and apply the manufacturer's recommended tightening torque. Lubricating the thread and aligning the assembly correctly help prevent vibration and extend service life.
For equivalences and interchangeability, SKF PHF SF taper bushings can replace similar fastening systems from other brands if the taper dimensions, shaft diameter and the number and location of holes match. Always verify tolerances and the tightening torque specified for each application. To ensure a safe replacement, compare the dimensions of the original bushing with the new one, and consult a specialist if you have doubts about compatibility.
If you need an SKF PHF SF taper bushing for your equipment, MR Industrial Accessories can help you choose the correct size. Send the full product code, such as PHF SF-40MM or PHF SF-55MM, via WhatsApp or email and we will quote you promptly. Our team can also suggest equivalents and assist with selection.

Frequently asked questions
- What does the designation PHF SF-…MM mean?
- PHF indicates an SKF taper bushing, SF the fastening variant with front screws, and …MM the shaft diameter in millimeters. For example, PHF SF-40MM is for a 40 mm shaft.
- How is an SKF PHF SF taper bushing mounted?
- Insert the bushing into the hub of the element to be fastened, align the holes and tighten the screws progressively in a cross pattern. Clean the surfaces and respect the recommended torque.
- Can I replace a bushing from another brand with this SKF one?
- Yes, as long as the taper dimensions, shaft diameter and hole locations match. Verify tolerances and tightening torque, and consult us if you have doubts.
