SKF SY 45 WF Bearing Housing - 45 mm Bore Unit

Technical Specifications & Construction

The bearing housing model SKF SY 45 WF features a 45 mm bore diameter insert bearing mounted within a cast-iron housing (bearing unit). Common specifications include dynamic load rating approx. 33.2 kN and limiting speed ~4 300 rpm. Additional key data: overall bearing width ~56.3 mm, centre-to-centre bolt distance ~143.5 mm. This robust design endows the unit with high stiffness, stable mounting and suitability for integration in bearing housings or mounted bearing units.

Industrial Applications & Advantages

This unit is tailored for industrial applications requiring reliable bearing support such as conveyor systems, mechanical drives, gearboxes, bearing housings and heavy-duty machinery. By incorporating the phrases “bearing unit”, “bearing housing”, “industrial applications”, “high durability”, “support for ball bearings”, we align with procurement-oriented search queries. The ready-to-mount configuration reduces installation time and simplifies MRO operations in B2B supply chains.

Main Description:

The SKF SY 45 WF bearing housing is a professional-grade mounted bearing unit designed for high-durability industrial installations. With a 45 mm bore diameter, it accommodates shafts of that size and forms part of an “obudowa łożyskowa” (bearing housing) or “jednostka łożyskowa” (bearing unit) that simplifies mounting in factory equipment. The cast-iron housing provides structural stability and resistance to deformation under load, while the insert bearing within ensures reliable rotation and long service life. Key design features like the eccentric locking collar and sealed insert bearing (often specified for this series) enable easy installation and maintenance. In industrial applications where minimal downtime and robust performance are essential—such as packaging lines, production conveyors, machine shops—this bearing housing delivers both performance and value. The use of terminology such as “łożysko kulkowe” (in reference to the ball bearing insert), “wysoka trwałość”, “obudowa łożyskowa” and “aplikacje przemysłowe” helps align with search demands from Polish-language engineers and buyers, as well as supporting international indexing via English phrases. The product supports a dynamic load rating of around 33.2 kN, making it suitable for moderate to heavy radial loads, and its limiting speed of approximately 4300 rpm offers adequate performance for many driven systems. Its dimensions (bolt-hole spacing, housing width, centre height) allow for integration into standard mounting frameworks without major redesign. For B2B purchasers looking to stock bearing units, this model offers a solution that addresses both the mechanical requirements and the logistical needs of quick turnarounds, availability and compatibility in “obudowa łożyskowa” systems.
