SKF FPXB series special bearings are units designed for applications where standard bearings do not perform: combined loads, moderate speeds and demanding service conditions. They are used in material handling equipment, cranes and slewing systems that require robust mounting and reliable sealing. At MR Accesorios Industriales we carry them as part of our SKF bearing line, with the technical backing of more than 80 years in the industry.

The FPXB series designation consists of a fixed prefix and a three-digit number that identifies the size. For example, FPXB 200 and FPXB 404 correspond to different sizes within the same family. The number does not indicate the diameter directly, but refers to a dimension table specific to the series. Any suffixes that may appear after the number refer to design variants: type of seal, internal clearance or surface treatment. To interpret a complete code, the best approach is to consult the manufacturer's dimension table or send us the code at MR and we will verify it.

These bearings are used in applications with rotating motion under combined axial and radial loads. They are commonly found in crane jibs, slewing tables, lifting equipment and solar panel orientation systems. They also appear in machinery for the food, cement and port industries, where the environment is aggressive and effective sealing is required. In Argentina, they are seen in road equipment, port cranes and production lines that need precise positioning.

To select an FPXB bearing, take into account the load it will support, the rotation speed and the environmental conditions. Sealing is key: if there is dust, water or particles, a variant with additional protection is advisable. Internal clearance must be suitable to avoid thermal overloads. During mounting, ensure correct alignment between the shaft and the housing, and proper lubrication according to the duty cycle. Poor alignment shortens service life even if the bearing is top quality.

As for equivalents, SKF special bearings can be replaced by products from other brands that follow the same dimensions and tolerances. There is no universal interchangeability: each manufacturer has its own codes and suffixes. What matters is comparing the complete designation, not just the number. If you need to replace an existing bearing, send us the code engraved on the product and the main dimensions; that way we can identify the best available option.
